Pitch Shifting using the Fourier Transform – Source Code
Explains how to do pitch shifting using the short-term Fourier transform. smbPitchShift.cpp contains the DSP code, there is also an example project that illustrates how to call smbPitchShift() using the miniAIFF library calls… [read more] NOTE: This code has nothing to do with our ZTX time stretching and pitch shifting!


miniAIFF Library
Implements a simple interface to read and write AIFF audio files. This library is a prerequisite for most of the example programs found on this site. Complete reference is also available, please use the below link. The library comes with demo projects for Microsoft Visual C, Xcode and a gcc Makefile… [read more]
