alisufian27

I have tried many options while record audio and i have not done all the options anyone here who help me to get the best quality of voice during recording.

mediaRecorder = new MediaRecorder();
mediaRecorder.SetAudioSource(AudioSource.Mic);
mediaRecorder.SetOutputFormat(OutputFormat.Mpeg4);
mediaRecorder.SetAudioEncoder(AudioEncoder.Aac);

You can use AudioSource.VoiceRecognition to replace the AudioSource.Mic, Because the AudioSource.Mic will record EVERYTHING. Soft taps on the table or keyboard, rustling of a plastic bag, someone coughing in the background, etc.Using AudioSource.VoiceRecognition will pass the audio data into the phone's noise cancellation filters before handing it over to you.

You can Capture all audio data to a byte array when recording and write all audio data to a temporary PCM file, save this somewhere like this link http://www.evklein.com/blog/Recording
