I'm using Audiomulch along with some VSTs to simulate VHF communication in Real Time. I would like to add a sound of a PTT (Push-to-talk) button when it's released and i would like it to be played automatically when it detects someone cease speaking (condition 1 sec silence). Is there a VST or other way that could be accomplished? Many thanks in advance
Can't you create the following kind of construction in Audiomulch?
while(thereIsInputSignal): If volume has been below x level for 1 sec: then play ptt.wav.
If not, then creating such VST wouldn't be too difficult (for someone who's done VSTs before) although an easier path could be to create a patch in Pure Data and then load it as VST using Camomile.
If it's not for real-time use, then you could merely process the entire sound file "offline" so that you generate another sound file with "ptt.wav" played in the spots where you recognized 1 sec or more of silence.
A manual solution would of course be to load the ptt.wav into a sampler and then listen through the track and record yourself playing that sound back whenever you think it should play.
