I need to re开发者_JS百科cord sound by using mobile's own microphone... How to do it?
It's explained here
Audio capture from the device is a bit more complicated than audio/video playback, but still fairly simple:
- Create a new instance of android.media.MediaRecorder using new
- Set the audio source using MediaRecorder.setAudioSource(). You will probably want to use MediaRecorder.AudioSource.MIC
- Set output file format using MediaRecorder.setOutputFormat()
- Set output file name using MediaRecorder.setOutputFile()
- Set the audio encoder using MediaRecorder.setAudioEncoder()
- Call MediaRecorder.prepare() on the MediaRecorder instance.
- To start audio capture, call MediaRecorder.start().
- To stop audio capture, call MediaRecorder.stop().
- When you are done with the MediaRecorder instance, call MediaRecorder.release() on it. Calling MediaRecorder.release() is always recommended to free the resource immediately.
Example:
To start recording:
        MediaRecorder audioRecorder = new MediaRecorder();
        audioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
        audioRecorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
        audioRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
        audioRecorder.setOutputFile(AUDIO_FILE_PATH);
        try {
            audioRecorder.prepare();
        } catch (IllegalStateException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        audioRecorder.start();
To stop recording:
        audioRecorder.stop();
        audioRecorder.release();
