how to make karaoke recording by recording voice (microphone) and music together but get each single in order to have a produced recording of single voice and other of single music and other of the both
OR TO HAVE THE ABILITY TO ADJUST VOLUME OF THE BOTH TO BE SUITABLE BEFORE PRODUCTION

cause when i clicked on mix i observed that every track must be same in the recording settings

and when i apply any track in the mix tab each gives echo while playing any sound and the laptop doesn't give it (even after applying stereo mix), and this happens when whether microphone or stereo mix starting playing sound

with much thanks
