Detailed Description

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;

Todo

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

Member Function Documentation

Init()

void daisysp::PitchShifter::Init ( float sr )

inline

Initialize pitch shifter

Process()

float daisysp::PitchShifter::Process ( float & in )

inline

process pitch shifter

SetDelSize()

void daisysp::PitchShifter::SetDelSize ( uint32_t size )

inline

sets delay size changing the timbre of the pitchshifting

SetFun()

void daisysp::PitchShifter::SetFun ( float f )

inline

sets an amount of internal random modulation, kind of sounds like tape-flutter

SetTransposition()

void daisysp::PitchShifter::SetTransposition ( const float & transpose )

inline

sets transposition in semitones
