I have a arduino uno and a MP3 shield.
And both working fine, i have made a little code that when i pressed a button, a mp3 file is playing.
But i want to make a Audio signal IN and audio OUT to and from my Ardion Uno, a schield or maybe a IC or something, that when i pressed the button, the audio from the cdplayer, mixer or what ever MUTE and the mp3 file is playing and when the file has stop playing, the audio signal wil be unmute.
So music is playing to audio IN and comes out to Audio Out, when pressed button, audio signal wil be MUTE, file is planing, when file is stop, the music wil be back.
Now its not the program code what i search but a methode, IC, shield or something where i can put in my audio signal and my audio out, that can made a mute, like a relais (i know relais is not the way to break the audio signal but than a better way) but controlled by Ardunio.
Anyone a idea how or example from little shield or IC?
