Detailed Description

class daisysp::PitchShifter;

Todo:

• move hash_xs32 and myrand to [dsp.h] and give appropriate names

time-domain pitchshifter

Author: shensley

Based on "Pitch Shifting" from ucsd.edu

t = 1 - ((s *f) / R)

where: s is the size of the delay f is the frequency of the lfo r is the sample_rate

solving for t = 12.0 f = (12 - 1) * 48000 / SHIFT_BUFFER_SIZE;
