![]() ![]() ![]() See also further reading for more details. The Vocoder module transforms the DFT spectral data according to the original algorithm, which is actually the instantaneous frequency estimation technique. ![]() The StftPitchShift module provides a full-featured audio processing chain to perform the pitch shifting of a single audio track, based on the built in STFT implementation.Įxclusively in the C++ environment the additional StftPitchShiftCore module can be used to embed this pitch shifting implementation in an existing real-time STFT pipeline. See more details in the build section.įeel free to check out some demos at stftPitchShiftDemo and the stftPitchShiftPlugin as well. In addition to the basic pitch shifting algorithm, it also features spectral poly pitch shifting and cepstral formant preservation extensions.īoth sources contain a ready-to-use command line tool as well as a library for custom needs. Both contain several function blocks of the same name (but different file extension, of course). This repository features two analogical algorithm implementations, C++ and Python. StftPitchShift is a Short-Time Fourier Transform ( STFT) based pitch and timbre shifting algorithm implementation, originally inspired by the Stephan M. ![]()
