Record audio that is being played from device to headphone jack

2018-06-11 14:24:06

I'm looking for a way to combine audio recorded from the device microphone with the sound that the device is playing.

Now you might say that it's an easy task, the microphone can record both BUT that's not the case because the audio that the device is playing is played to the headphone jack instead of the speakers.

Is there any way to do this?

I don't understand what you want. if you are talking about recording input source there are various source android OS provide to you such as MIC, DOWNLINK/Headphone speaker CAMCORDER etc...

Source Sode From android developer site

private void startRecording() {
        mRecorder = new MediaRecorder();
        mRecorder.setAudioSource(MediaRecorder.AudioSource.VOICE_DOWNLINK);
        mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
        mRecorder.setOutputFile(mFileName);
        mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);

        try {
            mRecorder.prepare();
        } catch (IOException e) {
            Log.e(LOG_TAG, "prepare() failed");
        }

        mRecorder.start();
    }
