Minor documentation updates for the AudioTrack class.

 *

 * <p>An AudioTrack instance can operate under two modes: static or streaming.<br>

 * In Streaming mode, the application writes a continuous stream of data to the AudioTrack, using

 * one of the write() methods. These are blocking and return when the data has been transferred

 * from the Java layer to the native layer and queued for playback. The streaming mode

 *  is most useful when playing blocks of audio data that for instance are:

 * one of the {@code write()} methods. These are blocking and return when the data has been

 * transferred from the Java layer to the native layer and queued for playback. The streaming

 * mode is most useful when playing blocks of audio data that for instance are:

 *

 * <ul>

 *   <li>too big to fit in memory because of the duration of the sound to play,</li>

 *   <li>too big to fit in memory because of the characteristics of the audio data

 *         (high sampling rate, bits per sample ...)</li>

 *   <li>received or generated while previously queued audio is playing.</li>

 * </ul>

 *

 * The static mode is to be chosen when dealing with short sounds that fit in memory and

 * that need to be played with the smallest latency possible. AudioTrack instances in static mode

 * can play the sound without the need to transfer the audio data from Java to native layer

 * each time the sound is to be played. The static mode will therefore be preferred for UI and

 * game sounds that are played often, and with the smallest overhead possible.

 * <p>Upon creation, an AudioTrack object initializes its associated audio buffer.

 * The size of this buffer, specified during the construction, determines how long an AudioTrack
