DESCRIPTION:
spectral freezing using Victor Lazzarini's pvsfreeze, that freezes the amplitude and frequency time functions of a pv stream according to a control-rate trigger.
CONTROLLERS:
ON/OFF - bypass
off/on - freezing switch for amplitudes AND frequencies
overlap - The distance in samples (“hop size”) between overlapping analysis frames
size - The FFT size in samples
mix - mix direct signal with effect
