Accessing the audio device directly

In addition to the Music and Sound interfaces Libgdx also provides two more low-level audio interfaces that enable direct access to the audio device. They can be used for recording and playback of raw samples of audio data. Those samples are stored as a PCM-encoded audio signal.

Note

Exploring the AudioDevice interface

The AudioDevice interface allows you to send PCM-encoded audio samples directly to the audio device. For this to work, a new audio device can be requested using Libgdx's Gdx.audio module and called by its newAudioDevice() method as follows:

  AudioDevice audioDevice =
      Gdx.audio.newAudioDevice(44100, false);
