Recording from mic - what are the new methods?

24 Oct 2017, 00:06

I spent the better of the past day trying to find ways to record up to a 2 minute clip and save it. The methods outlined here are all out of date for windows 8 or 10 https://autohotkey.com/board/topic/4955 ... even-work/

What would be a good way to do this? I currently use my iphone to record notes and thoughts, I can do much more if I have a control that lets me record quickly and then do actions with the recording that I can build including using speech commands to send it to a folder and so on. Main thing now is to even find if anything exists that works with windows 10 to do this task.

Here is a mci.ahk ,why are you not using the windows voice recorder?
Here is a link to recording using bass.dll you only have to set the correct device ,i do not have a microphone so cannot test it.

Title: MCI Library v1.1

Group: Overview

    This library gives the AutoHotkey developer access to the the Media Control
    Interface (MCI) which provides standard commands for playing/controlling
    multimedia devices.

    (end)

MCI Installation:

    To see a list of MCI devices that have been registered for the computer, go
    to the following registry locations...

    (start code)
    Windows NT4/2000/XP/2003/Vista/7/etc.:

      16-bit:
        HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\MCI

      32-bit:
        HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\MCI32


    Windows 95/98/ME:

        HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\MediaResources\MCI
    (end)

    To see a list of registered file extensions and the MCI device that has been
    assigned to each extension, go the following locations...

        (start code)
        For Windows NT4/2000/XP/2003/Vista/7/etc., this information is stored in
        the following registry location:

            HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\MCI Extensions

        For Windows 95/98/ME, this information is stored in the %windir%\win.ini
        file in the "MCI Extensions" section.
        (end)

Performance:

    AutoHotkey automatically loads winmm.dll into memory.  There is no need or
    advantage to preload this library in order to use the MCI library.

Debugging:

    *OutputDebug* statements in the core of some of the functions that only
    execute on condition are permanent and are provided to help the developer
    find and eliminate errors.

;
; Parameters:
;
;   p_lpszDeviceID - Device name or alias.
;
; Returns:
;
;   The return code from the <MCI_SendString> function which is 0 if the command
;   completed successfully.
;
; Remarks:

;
;   Identifies the current track.
;
; Parameters:
;
;   p_lpszDeviceID - Device name or alias.
;

;-----------------------------
;
; Function: MCI_DeviceType
;
; Description:
;
;   Identifies the device type name.
;
; Parameters:
;
;   p_lpszDeviceID - Device name or alias.
;
; Returns:
;
;   A device type name, which can be one of the following...
;
;       (start code)
;       cdaudio
;       dat
;       digitalvideo

    {
    MCI_SendString("capability " . p_lpszDeviceID . " device type",l_lpszReturnString)
    Return l_lpszReturnString
    }


;-----------------------------
;
; Function: MCI_Open
;
; Description:
;
;   Opens an MCI device and loads the specified file.
;
; Parameters:
;
;   p_MediaFile - A multimedia file.
;
;   p_Alias - Alias. A name such as media1. [Optional] If blank (the default),
;       an alias will automatically be generated.
;
;   p_Flags - Flags that determine how the device is opened. [Optional]
;
;   Flag Notes:
;   Some commonly used flags include...
;
;       (start code)
;       type {device_type}
;       sharable
;       (end)
;
;   If more than one flag is used, separate each flag/value with a space.
;   For example:
;
;       (start code)
;       type MPEGVideo sharable
;       (end)
;
;   Additional notes...
;
;     - The "wait" flag is automatically added to the end of the command string.
;       This flag directs the device to complete the "open" request before
;       returning.
;
;     - Use the "shareable" flag with care.  Per msdn, the "shareable" flag
;       "initializes the device or file as shareable. Subsequent attempts to
;       open the device or file fail unless you specify "shareable" in both the
;       original and subsequent open commands.  MCI returns an invalid device
;       error if the device is already open and not shareable.  The MCISEQ
;       sequencer and MCIWAVE devices do not support shared files."
;
;     - By default, the MCI device that is opened is determined by the file's
;       extension.  The "type" flag can be used to  1) override the default
;       device that is registered for the file extension or to  2) open a media
;       file with a file extension that is not registered as a MCI file
;       extension.  See the <Notes> section for more information.
;
;     - For a complete list of flags and descriptions for the "open" command
;       string, see the "MCI Reference Guide" in the <Links> section.
;
; Returns:
;
;   The multimedia handle (alias) or 0 (FALSE) to indicate failure.  Failure
;   will occur with any of the following conditions:
;
;    -  The media file does not exist.
;
;    -  The media file's extension is not a regisitered MCI extension.  Note:
;       This test is only performed if the "type" flag is not specified.
;
;    -  Non-zero return code from the <MCI_SendString> function.
;
; Remarks:
;
;   -   Use the <MCI_OpenCDAudio> function to open a CDAudio device.
;
;   -   After the device has been successfully opened, the time format is set to
;       milliseconds which it will remain in effect until it is manually set to
;       another value or until the device is closed.

;-----------------------------
;
; Function: MCI_Notify
;
; Description:
;
;   (Internal function.  Do not call directly)
;
;   This function has 2 responsibilties...
;
;    1) If called by the <MCI_Play> function, wParam contains the name of the
;       developer-defined function.  This value is assigned to the s_Callback
;       static variable for future use.
;
;    2) When called as a result of MM_MCINOTIFY message, this function will call
;       the developer-defined function (name stored in the s_Callback static
;       variable) sending the MM_MCINOTIFY status flag as the first parameter.
;
; Parameters:
;
;   wParam - Function name or a MM_MCINOTIFY flag.
;
;   MM_MCINOTIFY flag values are as follows...
;
;       (start code)
;       MCI_NOTIFY_SUCCESSFUL:=0x1
;           The conditions initiating the callback function have been met.
;
;       MCI_NOTIFY_SUPERSEDED:=0x2
;           The device received another command with the "notify" flag set and
;           the current conditions for initiating the callback function have
;           been superseded.
;
;       MCI_NOTIFY_ABORTED:=0x4
;           The device received a command that prevented the current conditions
;           for initiating the callback function from being met. If a new
;           command interrupts the current command and  it also requests
;           notification, the device sends this message only and not
;           MCI_NOTIFY_SUPERSEDED.
;
;       MCI_NOTIFY_FAILURE:=0x8
;           A device error occurred while the device was executing the command.
;       (end)
;
;   lParam - lDevID.  This is the identifier of the device initiating the
;       callback function.  This information is only useful if operating more

;   Pauses playback or recording.
;
; Parameters:
;
;   p_lpszDeviceID - Device name or alias.
;
; Returns:
;
;   The return code from the <MCI_SendString> function which is 0 if the command
;   completed successfully.

;
; Function: MCI_Play
;
; Description:
;
;       Starts playing a device.
;
; Parameters:
;
;   p_lpszDeviceID - Device name or alias.
;
;   p_Flags - Flags that determine how the device is played. [Optional] If
;       blank, no flags are used.
;
;       Flag Notes:
;
;       Some commonly used flags include...
;
;           (start code)
;           from {position}
;           to {position}
;           (end)
;
;       If more than one flag is used, separate each flag/value with a space.
;       For example:
;
;           (start code)
;           from 10144 to 95455
;           (end)
;
;       Additional notes...
;
;        -  With the exception of very short sound files (<300 ms), the "wait"
;           flag is not recommended.  The entire application will be
;           non-responsive while the media is being played.
;
;        - Do not add the "notify" flag unless you plan to have your script trap
;           the MM_MCINOTIFY message outside of this function.  The "notify"
;           flag is automatically added if the p_Callback parameter contains a
;           value.
;
;        -  For a complete list of flags and descriptions for the "play" command
;           string, see the "MCI Reference Guide" in the <Links> section.
;
;   p_Callback - Function name that is called when the MM_MCINOTIFY message is
;       sent. [Optional] If defined, the "notify" flag is automatically added.
;
;       Important:  The syntax of this parameter and the associated function is
;       critical.  If not defined correctly, the script may crash.
;
;       The function must have at least one parameter.  For example...
;
;           (start code)
;           MyNotifyFunction(NotifyFlag)
;           (end)
;
;       Additional parameters are allowed but they must be optional (contain a
;       default value).  For example:
;
;           (start code)
;           MyNotifyFunction(NotifyFlag,FirstCall=False,Parm3="ABC")
;           (end)
;
;       When a notify message is sent, the approriate MM_MCINOTIFY flag is sent
;       to the developer-defined function as the first parameter.  See the
;       <MCI_Notify> function for a description and a list of MM_MCINOTIFY flag
;       values.
;
;   p_hWndCallback - Handle to a callback window if the p_Callback parameter
;       contains a value and/or if the "notify" flag is defined. [Optional]  If
;       undefined but needed, the handle to default Autohotkey window is used.
;
; Returns:
;
;   The return code from the <MCI_SendString> function which is 0 if the command
;   completed successfully.

;           insert
;           overwrite
;           (end)
;
;       If more than one flag is used, separate each flag/value with a space.
;       For example:
;
;           (start code)
;           overwrite from 18122 to 26427
;           (end)
;
;
;       Additional notes...
;
;        -  The "wait" flag is not recommended.  The entire application will be
;           non-responsive until recording is stopped with a Stop or Pause
;           command.
;
;        -  For a complete list of flags and descriptions for the "record"

;   Converts the specified number of milliseconds to hh:mm:ss format.
;
; Parameters:
;
;   p_ms - Number of milliseconds.
;
;   p_MinimumSize - Minimum size.  [Optional] The default is 4.  This is the
;       minimum size in characters (not significant digits) that is returned.
;       Unless you want a ":" character to show as the leading character, don't
;       set this value to 3 or 6.
;
; Returns:
;
;   The amount of time in hh:mm:ss format with leading zero and ":" characters
;   suppressed unless the length is less than p_MinimumSize. Note:  If the
;   number of hours is greater than 99, the size of hour ("hh") will increase as
;   needed.
;
; Usage Notes:
;
;   To use this function to create separate variables for the number of hours,
;   minutes, and seconds, set the p_MinimumSize parameter to 8 and use simple
;   *SubStr* commands to create these variables.  For example:
;
;       (start code)
;       x:=MCI_ToHHMMSS(NumberOfMilliseconds,8)
;       HH:=SubStr(x,1,2)
;       MM:=SubStr(x,4,2)
;       SS:=SubStr(x,6,2)
;       (end)
;
;   To remove leading zeros from these variables, simply add 0 to the extracted
;   value.  For example:
;
;       (start code)
;       MM:=SubStr(x,4,2)+0
;       (end)

;   If a non-zero value is returned from the call to the mciSendString API
;   function, a call to the mciGetErrorString API function is made to convert
;   the error number into a developer-friendly error message.  All of this
;   information is sent to the debugger in an easy-to-read format.

Title: MCI Library v1.1

Group: Overview

    This library gives the AutoHotkey developer access to the the Media Control
    Interface (MCI) which provides standard commands for playing/controlling
    multimedia devices.

    MCIWAVE     waveaudio       Audio device that plays digitized waveform files
    (end)

MCI Installation:

    To see a list of MCI devices that have been registered for the computer, go
    to the following registry locations...

    (start code)
    Windows NT4/2000/XP/2003/Vista/7/etc.:

      16-bit:
        HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\MCI

      32-bit:
        HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\MCI32


    Windows 95/98/ME:

        HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\MediaResources\MCI
    (end)

    To see a list of registered file extensions and the MCI device that has been
    assigned to each extension, go the following locations...

        (start code)
        For Windows NT4/2000/XP/2003/Vista/7/etc., this information is stored in
        the following registry location:

            HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\MCI Extensions

        For Windows 95/98/ME, this information is stored in the %windir%\win.ini
        file in the "MCI Extensions" section.
        (end)

Performance:

    AutoHotkey automatically loads winmm.dll into memory.  There is no need or
    advantage to preload this library in order to use the MCI library.

Debugging:

    *OutputDebug* statements in the core of some of the functions that only
    execute on condition are permanent and are provided to help the developer
    find and eliminate errors.

;-----------------------------
;
; Function: MCI_DeviceType
;
; Description:
;
;   Identifies the device type name.
;
; Parameters:
;
;   p_lpszDeviceID - Device name or alias.
;
; Returns:
;
;   A device type name, which can be one of the following...
;
;       (start code)
;       cdaudio
;       dat
;       digitalvideo

    Return l_lpszReturnString
    }


;-----------------------------
;
; Function: MCI_Open
;
; Description:
;
;   Opens an MCI device and loads the specified file.
;
; Parameters:
;
;   p_MediaFile - A multimedia file.
;
;   p_Alias - Alias. A name such as media1. [Optional] If blank (the default),
;       an alias will automatically be generated.
;
;   p_Flags - Flags that determine how the device is opened. [Optional]
;
;   Flag Notes:
;   Some commonly used flags include...
;
;       (start code)
;       type {device_type}
;       sharable
;       (end)
;
;   If more than one flag is used, separate each flag/value with a space.
;   For example:
;
;       (start code)
;       type MPEGVideo sharable
;       (end)
;
;   Additional notes...
;
;     - The "wait" flag is automatically added to the end of the command string.
;       This flag directs the device to complete the "open" request before
;       returning.
;
;     - Use the "shareable" flag with care.  Per msdn, the "shareable" flag
;       "initializes the device or file as shareable. Subsequent attempts to
;       open the device or file fail unless you specify "shareable" in both the
;       original and subsequent open commands.  MCI returns an invalid device
;       error if the device is already open and not shareable.  The MCISEQ
;       sequencer and MCIWAVE devices do not support shared files."
;
;     - By default, the MCI device that is opened is determined by the file's
;       extension.  The "type" flag can be used to  1) override the default
;       device that is registered for the file extension or to  2) open a media
;       file with a file extension that is not registered as a MCI file
;       extension.  See the <Notes> section for more information.
;
;     - For a complete list of flags and descriptions for the "open" command
;       string, see the "MCI Reference Guide" in the <Links> section.
;
; Returns:
;
;   The multimedia handle (alias) or 0 (FALSE) to indicate failure.  Failure
;   will occur with any of the following conditions:
;
;    -  The media file does not exist.
;
;    -  The media file's extension is not a regisitered MCI extension.  Note:
;       This test is only performed if the "type" flag is not specified.
;
;    -  Non-zero return code from the <MCI_SendString> function.
;
; Remarks:
;
;   -   Use the <MCI_OpenCDAudio> function to open a CDAudio device.
;
;   -   After the device has been successfully opened, the time format is set to
;       milliseconds which it will remain in effect until it is manually set to
;       another value or until the device is closed.

;
; Function: MCI_Notify
;
; Description:
;
;   (Internal function.  Do not call directly)
;
;   This function has 2 responsibilties...
;
;    1) If called by the <MCI_Play> function, wParam contains the name of the
;       developer-defined function.  This value is assigned to the s_Callback
;       static variable for future use.
;
;    2) When called as a result of MM_MCINOTIFY message, this function will call
;       the developer-defined function (name stored in the s_Callback static
;       variable) sending the MM_MCINOTIFY status flag as the first parameter.
;
; Parameters:
;
;   wParam - Function name or a MM_MCINOTIFY flag.
;
;   MM_MCINOTIFY flag values are as follows...
;
;       (start code)
;       MCI_NOTIFY_SUCCESSFUL:=0x1
;           The conditions initiating the callback function have been met.
;
;       MCI_NOTIFY_SUPERSEDED:=0x2
;           The device received another command with the "notify" flag set and
;           the current conditions for initiating the callback function have
;           been superseded.
;
;       MCI_NOTIFY_ABORTED:=0x4
;           The device received a command that prevented the current conditions
;           for initiating the callback function from being met. If a new
;           command interrupts the current command and  it also requests
;           notification, the device sends this message only and not
;           MCI_NOTIFY_SUPERSEDED.
;
;       MCI_NOTIFY_FAILURE:=0x8
;           A device error occurred while the device was executing the command.
;       (end)
;
;   lParam - lDevID.  This is the identifier of the device initiating the
;       callback function.  This information is only useful if operating more
;       than one MCI device at a time.
;
; Returns:
;
;   Per msdn, returns 0 to indicate a successful call.
;
; Remarks:
;
;   This function does not complete until the call to the developer-defined
;   function has completed.  If a MM_MCINOTIFY message is issued while this
;   function is running, the message will be treated as unmonitored.
;
;------------------------------------------------------------------------------
MCI_Notify(wParam,lParam,msg,hWnd)
    {
;;;;;    Critical
        ;-- This will cause MM_MCINOTIFY messages to be buffered rather than
        ;   discared if this function is still running when another MM_MCINOTIFY
        ;   message is sent.

;
; Description:
;
;   Identifies the number of tracks on the media.
;
; Parameters:
;
;   p_lpszDeviceID - Device name or alias.
;
; Returns:
;
;   The number of tracks on the media.
;
; Remarks:
;
;   msdn: The MCISEQ and MCIWAVE devices return 1, as do most VCR devices.  The
;   MCIPIONR device does not support this flag.

;
; Function: MCI_Pause
;
; Description:
;
;   Pauses playback or recording.
;
; Parameters:
;
;   p_lpszDeviceID - Device name or alias.
;
; Returns:
;
;   The return code from the <MCI_SendString> function which is 0 if the command
;   completed successfully.
;
; Remarks:
;
;   msdn: With the MCICDA, MCISEQ, and MCIPIONR drivers, the pause command works
;   the same as the stop command.
;
;   Observation: For MCISEQ devices, pause works OK for me.
;
;------------------------------------------------------------------------------
MCI_Pause(p_lpszDeviceID)
    {
    Return MCI_SendString("pause " . p_lpszDeviceID . " wait")
    }


;-----------------------------
;
; Function: MCI_Play
;
; Description:
;
;       Starts playing a device.
;
; Parameters:
;
;   p_lpszDeviceID - Device name or alias.
;
;   p_Flags - Flags that determine how the device is played. [Optional] If
;       blank, no flags are used.
;
;       Flag Notes:
;
;       Some commonly used flags include...
;
;           (start code)
;           from {position}
;           to {position}
;           (end)
;
;       If more than one flag is used, separate each flag/value with a space.
;       For example:
;
;           (start code)
;           from 10144 to 95455
;           (end)
;
;       Additional notes...
;
;        -  With the exception of very short sound files (<300 ms), the "wait"
;           flag is not recommended.  The entire application will be
;           non-responsive while the media is being played.
;
;        - Do not add the "notify" flag unless you plan to have your script trap
;           the MM_MCINOTIFY message outside of this function.  The "notify"
;           flag is automatically added if the p_Callback parameter contains a
;           value.
;
;        -  For a complete list of flags and descriptions for the "play" command
;           string, see the "MCI Reference Guide" in the <Links> section.
;
;   p_Callback - Function name that is called when the MM_MCINOTIFY message is
;       sent. [Optional] If defined, the "notify" flag is automatically added.
;
;       Important:  The syntax of this parameter and the associated function is
;       critical.  If not defined correctly, the script may crash.
;
;       The function must have at least one parameter.  For example...
;
;           (start code)
;           MyNotifyFunction(NotifyFlag)
;           (end)
;
;       Additional parameters are allowed but they must be optional (contain a
;       default value).  For example:
;
;           (start code)
;           MyNotifyFunction(NotifyFlag,FirstCall=False,Parm3="ABC")
;           (end)
;
;       When a notify message is sent, the approriate MM_MCINOTIFY flag is sent
;       to the developer-defined function as the first parameter.  See the
;       <MCI_Notify> function for a description and a list of MM_MCINOTIFY flag
;       values.
;
;   p_hWndCallback - Handle to a callback window if the p_Callback parameter
;       contains a value and/or if the "notify" flag is defined. [Optional]  If
;       undefined but needed, the handle to default Autohotkey window is used.
;
; Returns:
;
;   The return code from the <MCI_SendString> function which is 0 if the command
;   completed successfully.

;           insert
;           overwrite
;           (end)
;
;       If more than one flag is used, separate each flag/value with a space.

;           (end)
;
;
;       Additional notes...
;
;        -  The "wait" flag is not recommended.  The entire application will be
;           non-responsive until recording is stopped with a Stop or Pause
;           command.
;
;        -  For a complete list of flags and descriptions for the "record"

; Description:
;
;   Converts the specified number of milliseconds to hh:mm:ss format.
;
; Parameters:
;
;   p_ms - Number of milliseconds.
;
;   p_MinimumSize - Minimum size.  [Optional] The default is 4.  This is the
;       minimum size in characters (not significant digits) that is returned.
;       Unless you want a ":" character to show as the leading character, don't
;       set this value to 3 or 6.
;
; Returns:
;
;   The amount of time in hh:mm:ss format with leading zero and ":" characters
;   suppressed unless the length is less than p_MinimumSize. Note:  If the
;   number of hours is greater than 99, the size of hour ("hh") will increase as
;   needed.
;
; Usage Notes:
;
;   To use this function to create separate variables for the number of hours,
;   minutes, and seconds, set the p_MinimumSize parameter to 8 and use simple
;   *SubStr* commands to create these variables.  For example:
;
;       (start code)
;       x:=MCI_ToHHMMSS(NumberOfMilliseconds,8)
;       HH:=SubStr(x,1,2)
;       MM:=SubStr(x,4,2)
;       SS:=SubStr(x,6,2)
;       (end)
;
;   To remove leading zeros from these variables, simply add 0 to the extracted
;   value.  For example:
;
;       (start code)
;       MM:=SubStr(x,4,2)+0
;       (end)

; Function: MCI_ToMilliseconds
;
; Description:
;
;   Converts the specified hour, minute and second into a valid milliseconds
;   timestamp.
;
; Parameters:
;
;   Hour, Min, Sec - Position to convert to milliseconds
;
; Returns:

;-----------------------------
;
; Function: MCI_SendString
;
; Description:
;
;   This is the primary function that controls MCI operations.  With the
;   exception of formatting functions, all of the functions in this library call
;   this function.
;
; Parameters:
;
;   p_lpszCommand - MCI command string.
;
;   r_lpszReturnString - Variable name that receives return information.
;       [Optional]
;
;   p_hwndCallback - Handle to a callback window if the "notify" flag was
;       specified in the command string.  [Optional] The default is 0 (No
;       callback window).
;
; Returns:
;
;   Two values are returned.
;
;    1) The function returns 0 if successful or an error number otherwise.
;
;    2) If the MCI command string was a request for information, the variable
;       named in the r_lpszReturnString parameter will contain the requested
;       information.
;
; Debugging:
;
;   If a non-zero value is returned from the call to the mciSendString API
;   function, a call to the mciGetErrorString API function is made to convert
;   the error number into a developer-friendly error message.  All of this
;   information is sent to the debugger in an easy-to-read format.

If you are still interested, I've added a link to the MCI v1.1 project in the Collection of lost AHK Scripts & Libraries thread. The project includes the library and several example scripts. You can find the post here.

WOW thank you, is there any ready script that would record but only voice and make a file. What I mean is, if I start to record a 5 minute clip it will pause when it detects no sound?

Thanks

To answer your question: No, there is no ready script (at least for me) that can do this. However, it "sounds" (sorry, had to pun it up) doable.

Just a few thoughts...

The solution would probably require multiple threads. One thread to do the main stuff -- start, stop, pause, resume, save, etc. -- and another thread to check the microphone levels. The threads would communicate with each other through global variables. The primary thread would pause recording when the microphone level goes quiet for a pre-determined amount of time (Ex: 3 seconds) and would resume recording when the microphone became active again. There might be a short gap in the recording if the user abruptly resumed speaking.

These are just my thoughts. I have no earthly idea whether this will work or not but like I said, it sounds doable.

Thanks! In python I tested a script like that see deenu's code on this page https://stackoverflow.com/questions/892 ... n/43304429
so im sure its doable in ahk too

Using the code from: https://autohotkey.com/boards/viewtopic.php?t=34352

You can add level monitoring and when it falls below a certain level just halt the writing to the wav file in the RecordFunction.( add a condition to file.rawwrite(buffer+0,length) )

monitoring the recording level with tooltip :

Code: Select all

level:
  LevelDWord := DllCall("BASS\BASS_ChannelGetLevel", UInt,hrecord)
  leftlevel := LevelDWord & 0xffff
  Rightlevel := (LevelDWord>>16) & 0xffff

  tooltip % Floor(leftlevel*0.04) "     " Floor(Rightlevel*0.04)
Return

Here is the testcode i used ( sorry very messy .....),it works on winXp ( i have a webcam with microphone there) but i cannot test it on win10 as you can see no devices are found which is correct :)

Re: Recording from mic - what are the new methods?

Dear noname,

Is there a stable way to set up an EQ for this script? I've added the one you once made for that Chilltrax ♥ bass-player if i remember well.
I'm glad you enjoyed Chilltrax by the way ☺ Yes that was me.

So I removed the writing to file (not needed for me atm) and made it monitor just the buffer so you can see audio input visually but it tends to crash very regularly..
Like it doesn't stay alive for longer than a few seconds. I'm sure I'm not doing it like you're supposed to as the mad scientist approach tends to blow up sometimes (a lot)!

Anyhow, any help would be greatly appreciated. Especially since I've been struggeling with this for quite some time now as you might remember. (EQ Monitor)

Happy New Year everyone! May 2018 treat you and your loved ones well.

Thought I would post this other way to show an audio meter for reference. Code was taken from this post https://autohotkey.com/boards/viewtopic.php?t=19078

Code: Select all

#SingleInstance, Force
#include VA.ahk
MeterLength = 20
audiomic := VA_GetDevice("capture")
audioMeter := VA_GetAudioMeter(audiomic)

VA_IAudioMeterInformation_GetMeteringChannelCount(audioMeter, channelCount)

; "The peak value for each channel is recorded over one device
;  period and made available during the subsequent device period."
VA_GetDevicePeriod("capture", devicePeriod)

Loop
{
    ; Get the peak value across all channels.
    VA_IAudioMeterInformation_GetPeakValue(audioMeter, peakValue)    
    meter := MakeMeter(peakValue, MeterLength)

        meter .= "`n" MakeMeter(NumGet(peakValues, A_Index*4-4, "float"), MeterLength)

    ToolTip, %meter%
    Sleep, %deviceperiod%
}

MakeMeter(fraction, size)
{
    global MeterLength
    Loop % fraction*size
        meter .= "|"
    Loop % (1-fraction)*size
        meter .= "."
    meter .= "  " fraction
    return meter
}
The following is a concept I tried for a deaf gamer who needed a visual indicator of when sound played. Can be adapted to run other task such as stopping a recording.
Uses tidbit's Window Effects (WE_) WinShake function which I put in instead of including the whole lib.

Code: Select all

#SingleInstance, Force
#include, VA.ahk
MeterLength = 30

audioMeter := VA_GetAudioMeter()

VA_IAudioMeterInformation_GetMeteringChannelCount(audioMeter, channelCount)

; "The peak value for each channel is recorded over one device
;  period and made available during the subsequent device period."
VA_GetDevicePeriod("capture", devicePeriod)

Loop
{
    ; Get the peak value across all channels.
    VA_IAudioMeterInformation_GetPeakValue(audioMeter, peakValue)    
    meter := MakeMeter(peakValue, MeterLength)
    
    ; Get the peak values of all channels.
    VarSetCapacity(peakValues, channelCount*4)
    VA_IAudioMeterInformation_GetChannelsPeakValues(audioMeter, channelCount, &peakValues)
    Loop %channelCount%
        meter .= "`n" MakeMeter(NumGet(peakValues, A_Index*4-4, "float"), MeterLength)

    ToolTip, %meter%
	if (peakValue > 0.06) 
	{
		gosub, shake
	}
    Sleep, %devicePeriod%
}

MakeMeter(fraction, size)
{
    global MeterLength
    Loop % fraction*size
        meter .= "|"
    Loop % (1-fraction)*size
        meter .= "."
    meter .= "  " fraction
    return meter
}

shake:
WE_WinShake("PVP.net Client", 10, 8, 2)
return

WE_WinShake(WE_window="", WE_shakes=20, WE_xrattle=2, WE_yrattle=3)
    {
    WinGetPos, WE_mywinx,WE_mywiny , , , %WE_window%
    Loop, %WE_shakes%
        {
        Random, WE_rattlex,  WE_mywinx-WE_xrattle,  WE_mywinx+WE_xrattle
        Random, WE_rattley,  WE_mywiny-WE_yrattle,  WE_mywiny+WE_yrattle
        WinMove, %WE_window%,, %WE_rattlex%, %WE_rattley%
        }

Re: Recording from mic - what are the new methods?

01 Jan 2018, 16:29

Hi Tygerbyte

Thanks for the swift reply. I actually came from VA before I went to Bass.dll for it's capability of getting a somewhat detailed view on the audio frequencies.

The second script works fine indeed for audio level detection. (the first one fails here)

Yet for me it is quite important to be able to visualize the frequencies separatly and VA is not able to do that from what I know.
AudioLevel.dll from Rainmeter can do it too - like bass.dll - but I have no idea on how to get that to work in AHK.
I clearly lack experience when it comes to working with Dynamic Link Libraries and Calls to those I guess.

Still I'm sure your visual indicator script will come in handy somewhere so thanks for sharing that and great initiative for helping that person out this way.

Cheers

Thanks. I might have a solution for the microphone issue 8-)
You can choose the Stereo Mix recording device where all sound output passes through. Just play some music or so.

I've made a compact version using your player and the recording demo you linked. Check it out :
(warning: it crashes often. AHK exit code 3221225477 and 3221226356 or BASS error 5 BASS_ERROR_HANDLE invalid handle, see below)
Spoiler
I've tried many other ways using my VA "EQ" scripts that I converted to Bass but all tend to be unstable when i use the recordingbuffer.
Hope we can figure this one out but with this compact script it should be easier at least, and you know this script already :beer:
I'm betting it will provide a solution for my other experiments as well since the culprit is likely to be the same.

About the error codes :

- The bass invalid handle error just pops up now and then and then goes away. Likely due to one or both of the following.
- The 3221226356 STATUS_HEAP_CORRUPTION error points to writing to unallocated or uninitialized memory causing undefined and unpredicatable behaviour.
- The 3221225477 STATUS_ACCESS_VIOLATION error may point to the handle being lost due to the dll being unloaded after a call, if not loaded as library first.

It could also be due to the good old UInt/UPtr, Int/Ptr and VarSetCapacity mix-ups I suppose :facepalm:
Some info I found from Lexikos regarding those https://autohotkey.com/boards/viewtopic.php?t=13204

Thanks, that worked to test it and as you found out after a few seconds it crashed.I borrowed a mic and monitored playing mp3.
Maybe not the most "professional" solution but if channelgetdata returns -1 ........ignore it.....and wait for a better one ?

Best of luck.

Re: Recording from mic - what are the new methods?

Thanks for the assisstance. No more crashes finally!
Yes, I think that will do nicely. The channeldata is not a big issue.

If you wouldn't mind I'd love to know how this works logically:
t :=110-NumGet(buf,4*(A_Index-1),"Float")*3000
As I don't quite grasp it. Like why 110 and 3000 ?
I noticed those changed so I figured I'd ask.

Like why 110 and 3000 ?
It is just to scale it and get it fitted into the window dimensions.The window height is 120 ,if the output of "NumGet(buf,4*(A_Index-1),"Float")*3000" is 0 then the yposition is 110-0=110 or the baseline is 10 above bottom (120-110) .If the output is higher the value gets smaller so ypos goes up in the window.

The 3000 is just try and error to get a value that is around 100 when i kick my mic ...............

Greetings and i have to thank you i just learned a few things in win10 and gave me ideas :D

Really glad to hear that gave you some ideas. And thanks for the info again ;) Makes sense now.
Feel free to share your experiments with us, I think I can speak for everyone saying we're always looking forward to see them.
