PVInfo return mag and freq data from a CSound pv

#mag, freq = PVInfo.ar(pvbuffer, binNum, filePointer, mul, add )

#mag, freq = PVInfo.kr(pvbuffer, binNum, filePointer, mul, add )

Here is a short prose explanation of what the UGen does, and any other relevant points.

pvbuffer - explanation of pvbuffer. Default value is nil.

binNum - explanation of binNum. Default value is 0.

filePointer - explanation of filePointer. Default value is 0.

mul - explanation of mul. Default value is 1.

add - explanation of add. Default value is 0.
