Collection of audio utilities for decoding/encoding files and streams.

  • Not based on ffmpeg/libav/libavcodec/libavformat and alike
  • Channel-based audio consumption/filter chain
  • Raw sample analyzer channels
  • AnalyzerChannel channels / mergers / splitters / trimmers
  • Audio resampler
  • Audio downmixing to stereo/mono
  • Multi-codec decoder and encoder
  • Multi-format packetizers
