android-mediarecorder

I am using the MediaRecorder for audio recording in android. I receive very poor audio quality when I record. I checked iPhone recording, and it is very good, but in android I receive horrible sound. For sound recording I use: recorder = new MediaRecorder(); recorder.setAudioSource(MediaRecorder.AudioSource.MIC); recorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT); recorder.setAudioEncoder(MediaRecorder.AudioSource.DEFAULT); recorder.setOutputFile(path); recorder.prepare(); recorder.start(); How do I improve Audio Recording quality? Try this one - recorder = new MediaRecorder();

This is a pretty difficult problem to solve generally using android assuming that you are attempting to add the text to the actual video file, and not simply displaying a TextView over a VideoView .
