  • IIR filter design
    • Butterworth
    • Chebyshev type I and II
    • Bessel
    • Lowpass, highpass, bandpass and bandstop filters
    • Conversion of arbitrary filter from Z,P,K to SOS format (suitable for biquad function and filter)
  • Discrete Cosine Transform type II (and its inverse, also called DCT type III)
  • cmake uninstall target (thank to @acxz)
  • C API: DFT, real DFT, DCT, FIR and IIR filters and convolution, memory allocation
    • Built for SSE2, SSE4.1, AVX, AVX2, AVX512, x86 and x86_64, architecture is selected at runtime
    • Can be used with any compiler and any language with ability to call C functions
    • Prebuilt windows binaries
  • C++17
    • Inline variables
    • Fold expressions
    • Structured binding
  • New vector based types: color, rectangle, point, size, border, geometric vector, 2D matrix
  • Color space conversion (sRGB, XYZ, Lab, LCH)
  • MP3 file reading (using third party dr_lib library, see source code for details)
  • Various optimizations and fixes (thank to @bmanga, @ncorgan, @rotkreis, @mujjingun for fixes and bug reports)

Release notes

  • MSVC support is limited to MSVC2017 due to ICE in MSVC2019. Once fixed, support will be added
  • DFT is limited to Clang due to ICE in MSVC and broken AVX optimization in GCC 8 and 9. Once fixed, support will be added
