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