I am working on a project dealing with bluetooth audio. The audio signal is good, however, when the bluetooth module senses that the music is paused, the bluetooth module will go into a standby mode. When this happens, there is a pop that happens. The pop also happens when you press play again, and the bluetooth module wakes up. Is there a way to filter this spike? or I was trying to figure out a way to have a delay (if music has been playing for about 2 seconds, then allow the audio to play otherwise don't) before audio is passed through. Any suggestions would be greatly appreciated. My initial solution was to put an inductor at the output after my op amp which the audio from the bluetooth module is being amplified.
