I am working with an Arduino and am trying to get it to respond to sound when it is played on my computer. I'm communicating with it over a serial port.
I need to know if there are any audio/sound monitoring tools that will work from the command line so I could write a shell script to do everything. Something similar to
airmon-ng for wireless (Although not exactly like this as this monitors external stats. I'm looking for something that can do this internally).
I'm not sure if such a tool exists because I couldn't seem to find the right combination of keywords to find it on google. This is for an audio-out listener. I think similar tools exist for line-in.
