Programming Volume Control (WAV trigger)

Hi all,

The project seems simple enough: use a WAV trigger to play audio, and use 2 triggers to control audio of 2 tracks.

I want to use trigger 1 to start playing 3 different tracks - all synchronized at all times (an important detail).

I want to use trigger 2 to mute track 3 but hear track 2.

I want to use trigger 3 to mute track 2 but hear track 3.

Again, all without stopping and starting the track during switches; I want trigger 2 and 3 to only function as volume control using a single pole double throw relay connected to a push to talk button (scripted demo of walkie-talkie).

I can’t seem to figure out how I can accomplish this… even after spending hours searching. It seems this is a unique programming problem - and I’m not much of a programmer lol.

Maybe someone with more programming IQ has an idea on how I can do this - or if not, suggest a viable alternative (alternate programming? another audio controller connected via FTDI?)… it’s probably relatively simple for someone with more know-how… but I just don’t even know where to begin tbh!

I’d greatly appreciate help!

Which board do you plan to use?
