Reverb left/right is the delay between every + * bounce in milliseconds. 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. + * + * 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).
