is there any way or any voice recorder app that works in the background for IOS 15?

In IOS 14.0.8 the solution was to use simultaneously with (MIC on in-game) a voice recorder application in the background! On IOS 15.0.2 this method stopped working! In IOS 15.0.2 does not allow 2 MIC’s working at the same time! You activate the MIC and IOS understands it as a call and changes the audio of all APPS to MONO! In games, for example: COD Mobile, PUBG and Free Fire the sound is mono and not Stereo! unplayable!
