Key to play sound while pressed

[Elaphe666]

I know how to play a sound with a hotkey, but is it posible to have a beep sound and keep it sounding as long as you hold that key down, just like the way a car horn works? I think I could make a long wav and make the hotkey detect when the key is relased and at that point interrupt the sound play... Any idea?

To the best of my knowledge, there is no way for AutoHotkey to create an infinitely long sound - the sound length will be limited to the length of the WAV file you create. However, it is certainly possible to play the sound repeatedly while a key is held down (IE: like an alarm - beep beep beep beep). This should work for any length WAV file (or even a simple system beep)...

Code: Select all

F12:: 	; Replace this with the key of your choice.
SoundToPlay := "*-1"  	; *-1 is the SoundPlay code for the system beep.   You can change this to any other SoundPlay code or to a WAV file path & name.
While GetKeyState(A_ThisHotKey, "P")
{
	If SoundPlaying
		Continue
	Else
		SetTimer, PlayTheSound, -1
}
SoundPlay, DoesNotExist.avi  	; This aborts any currently playing sound file.
Return
 
PlayTheSound:
SoundPlaying := True
SoundPlay, %SoundToPlay%, Wait
If InStr(SoundToPlay, "*")  	; This gives a little time for the system sounds to play, since they ignore the Wait switch.
	Sleep 500
SoundPlaying := False
Return

Hello @Shadowpheonix
can I use only to notify on cntl key when pressed?
I tried, but it just work on combination with ! or ^ or +, but they alone it does not work.
e.g; ^d:: is ok but ^:: alone does't work and give the sound!, it considered that as the letter '^' instead of cntl

(because I had a problem in cntl that it does randomly press by its own, i.e; stuck, and I want to check when it does that)
thanks

^ is a special symbol in AutoHotkey which represents the Ctrl key when used in combination with another key. If you want a hotkey that triggers when Ctrl is pressed by itself, you need to use Ctrl::.
