/**
 * <h3>4.13.   Reverb</h3>
 * <p/>
 * <p>   Yet another subjective frame, with which you can adjust echoes of<br>    different kinds.
 * Reverb left/right is the delay between every bounce<br>    in ms. Reverb bounces left/right is the number
 * of bounces that should<br>    be made. $FF equals an infinite number of bounces. Feedback is the<br>
 *    amount of volume that should be returned to the next echo bounce. $00<br>
 * <p/>
 *    is 0%, $FF is 100%. If this value were $7F, there would be 50% volume<br>    reduction on the
 * first bounce, 50% of that on the second and so on.<br>    Left to left means the sound from the left bounce
 * to be played in the<br>    left speaker, while left to right means sound from the left bounce to<br>
 *    be played in the right speaker.</p>
 * <p/>
 * <p>   'Premix left to right' is the amount of left sound to be mixed in the<br>    right before
 * any reverb is applied, where $00 id 0% and $FF is 100%.<br>    'Premix right to left' does the same thing,
 * but right to left.<br>    Setting both premix to $FF would result in a mono output (if the<br>   
 * reverb is applied symmetric). There may only be one "RVRB"
 * <p/>
 * frame in<br>    each tag.</p>
