* @return An array of audio encodings (e.g. {@link AudioFormat#ENCODING_PCM_16BIT},
* {@link AudioFormat#ENCODING_PCM_FLOAT}) supported by the audio device.
* <code>ENCODING_PCM_FLOAT</code> indicates the device supports more
* than 16 bits of integer precision. Specifying <code>ENCODING_PCM_FLOAT</code>
* with {@link AudioTrack} or {@link AudioRecord} can preserve at least 24 bits of
