PV_BinScramble scramble bins


PV_BinScramble(buffer,  wipe,  width,  trig)


Randomizes the order of the bins.

The trigger will select a new random ordering.

buffer - fft buffer.

wipe - scrambles more bins as wipe moves from zero to one.

width - a value from zero to one, indicating the maximum randomized distance of a bin from its

original location in the spectrum.

trig - a trigger selects a new random ordering.
