/**
|
|
* The <i>Reverb</i> is yet another subjective frame, with which you can adjust
|
|
* echoes of different kinds. 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). There
|
|
* may only be one RVRB frame in each tag.
