how to enhance the sound quality while recording the sound? I want to enhance the sound quality while recording the sound on the android device, Is there and external device which is used for this. If yes then tell me for this I'll be thankful to you.
You can use any ordinary microphone that uses unbalanced connectors with suitable adaptors like this 3,5mm one. However, the resulting quality will depend on the DACs of the device and the application used, an external mic can only do so much.
