How to record audio file in Android

Question

I am working in android. How can I record an audio file through microphone, and how can I save the recorded file in the emulator?

Answer 1

I had tried to record the WAV file in android. But somehow, it is only recording the. WAV file in stereo only and you should use the audio recorder with the following parameter

recorder = new AudioRecord(MediaRecorder.AudioSource.MIC,
                        RECORDER_SAMPLERATE, AudioFormat.CHANNEL_IN_MONO,RECORDER_AUDIO_ENCODING, bufferSize);

        recorder.startRecording();

and from the recorder, you need to write all the data into one file and also you need to give header information

then just do

recorder.stopRecording();

but I have just one problem in this is even if I give AudioFormat.CHANNEL_IN_MONO..it still record in stereo format. Hope my answer helps you.
