pvcompand~ pvcompand~ either expands or compresses the differences between the amplitudes of the spectral frames. pvcompand~ either expands or compresses the differences between the amplitudes of the spectral frames. The threshold is interpreted as dB and useful ranges are from about -60 to +60. Positive values increase the "peakiness" of the sound and negative values tend to whiten the spectrum.	from the library : FFTease Format : External Environment : msp / PD freeware Max 3.x / 4.x http://www.sarc.qub.ac.uk/~elyon/LyonSoftware/MaxMSP/FFTease/
