I'm trying to get the active levels of my microphone, however, there seems to be something wrong with VA_IAudioMeterInformation_GetPeakValue(audioMeter, peakValue) as it always returns null

Here is my code

[Lexikos]

VA_GetAudioMeter expects a device_desc, the same as VA_GetDevice's first parameter. When you pass it a pointer value, it is misinterpreted as a numeric index. In retrospect, a pointer value is extremely unlikely to ever be in the range of a valid index, so VA_GetDevice (which is used internally by functions such as VA_GetAudioMeter) could simply return the value it is given as-is. However, in this case you have no need for the device pointer anyway.

Instead pass the device name directly to VA_GetAudioMeter, or pass "capture" to use your default recording device.

Also, the "playback" in VA_GetDevicePeriod("playback",...) should be changed to whatever device_desc is passed to VA_GetAudioMeter.


Edit: I've updated VA.zip so that VA_GetDevice(device_pointer) will return device_pointer. I also fixed a "pointer leak" in VA_GetAudioMeter.

Ahh, that works perfectly. Thank you

Sorry for the double post, but I noticed something odd. The levels are only displayed if another program starts up the capture drivers. For example, if I load up Audacity and hit record, or open up recording devices (which has a meter next to ever device) only then does this script show the meters.

If I close out all programs that, upon exit, disable the record drivers, the meters for this script go back down to 0.

I'm no expert at calling the proper drivers so how exactly do I load up my main capture device driver?

Ahh gotcha Lexikos, didn't really read that. Thanks for the script nontheless. Works like a charm for output devices. I'll try to find a way to load the input device and will post my solution when (and if) I find it.

Hi,
First of all thanks for the script, it makes the move to windows 7 seem a bit less painful. :p

I'm having a small problem though. I use hotkeys to control the volume on line in coming from my ps3. It works great except for when I lower the volume down to 0 and then press twice on the volume down key. The sound level goes up to 89 and it'll get ear shatteringly loud. The same thing doesn't happen if I try to increase the volume over 100, not that it'd matter much if it did. :>

Here's my code, hope you can help me.

Thanks for the bug report. I've fixed a divide-by-zero error in VA_SetVolume which seemed to be the cause. Please download and try again.

Seems to work flawlessly now. Thanks for the quick response!

Is it possible with application specific sound control in windows 7 with this script?

Lets say if you only want to mute the sound in a specific program, but let others stay the same volume.

From the device pointer (IMMDevice Interface), you need to create and initialize an audio client (IAudioClient Interface). It can be tricky to call the interface functions correctly, so I've written a complete example:

Can this library be used to set app-specific volume levels visible in the Win7 audio mixer? My mp3/TV/video players produce uneven audio levels. When a particular player starts, I'd like to set the relevant application volume to, say, 50% of current master volume. I can do this manually in the mixer and it works. However, every now and then I may inadvertently hit an app-specific volume hotkey, and the app will reset its volume level to 100%. Then I have to adjust the level manually again. I want to automate this.
