PVSynth resyntesize data with a bank of sine tones from a CSound PV analysis file

PVSynth.ar(pvbuffer, numBins, binStart, binSkip, filePointer, freqMul, freqAdd, mul, add )

This currently only works with .pv files. .pvx and CSound 5 files will be implemented soon.

DANGER! The values stored inside the pv file for magnitudes are NOT scaled to a linear amplitude system. See PVFile (and the example below) for suggestions on how to scale these values so you don't destroy things.

pvbuffer - The buffer containing pv data (stored with PVFile)

numBins - The number of bins to resynthesize. Default is 0.

binStart - The bin number to start on. Default value is 0.

binSkip - The number of bins to skip. Default value is 1.

filePointer - A pointer into the soundfile. 0.0 is the beginning, 1.0 is the end. Default value is 0.

freqMul - Freq value scaler. Default value is 1.0.

freqAdd - Freq value offset. Default value is 0.0.
