It's urgent. I use MediaRecorder to record audio and it will release a .3gpp file. Then I use MediaPlayer to play the audio which is just recorded. The quality is poor. It is played at half speed. if I record 10s, it will be played 20s. I don't have a device so all the operation is did in the emulator. Why could that happened? It seems that others don't have the problem. How to deal with it.Thank you very much.
try to use other format, like this: MediaRecorder recorder = new MediaRecorder(); recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
