It is dual-licensed under GPLv2+ and a commercial license.

Among its features:

  • Discrete Fourier Transform (aka DFT), Fast Fourier Transform (aka FFT) and related algorithms, such as convolution and correlation.
  • High quality Sample Rate Conversion.
  • Biquad filters and filter design.
  • IIR filter design.
  • FIR filters and design.
  • EBU R 128 Loudness.
  • Window functions.
  • Tensor and matrix operations.
  • Goertzel, Stereo mixing, DC removal, A-, B- and C- weighting.
  • Mathematical and statistical functions.
  • Audio file reading/writing.
  • Pseudorandom number generator.
