bqfft

A small library wrapping various FFT implementations for some common audio processing use cases. Note this is not a general FFT interface, as it handles only power-of-two FFT sizes and real inputs.

Requires the bqvec library.

This code originated as part of the Rubber Band Library written by the same authors (see https://bitbucket.org/breakfastquay/rubberband/). It has been pulled out into a separate library and relicensed under a more permissive licence.

C++ standard required: C++98 (does not use C++11 or newer features)

  • To compile on Linux: Edit Makefile to select implementation, then make test. Do read the notes in the Makefile, and don't attempt to use the default implementation, which is very slow
  • To compile on macOS: make -f build/Makefile.osx test
