loop_crossfade
Loop cross fade.
This can be used to add a crossfade to a loop where the looped sample does not have the crossfade "baked into" its audio data.
Practical Considerations
This opcode is uinimplemented in most SFZ players, but it is avaialble in OpenMPT and sfizz. sfizz currently uses a sinusoidal formula as default.
\[ amp = (1-cos(pi*x))/2 \]
OpenMPT's crossfade implementation currently applies a fade halfway between a constant volume fade and constant power fade.
\[ amp = pow(x, 0.75) \]
