Kirika

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

Codecs supported

Codec Containers Decoder Analyzer Encoder Notes
FLAC FLAC, Ogg ✅ ✅ ✅ Adjustable encoding compression level and block size.
TTA TTA ✅ ✅ ✅ Only 16bit encoding
MP3 MP3 ✅ - ✅ Adjustable encoding bitrate and mode. Decoding via minimp3, encoding via LAME.
Opus Ogg ✅ - ✅ Adjustable encoding bitrate.
Vorbis Ogg ✅ - ❌
AAC ADTS ❌ - ✅ Adjustable encoding bitrate and mode (LC, HEv2).

Container packetizers supported

Container Packetizer Keep Mode Sample Number
FLAC ✅ ✅ ✅
TTA ❌ - -
MP3 ✅ ✅ ✅
Ogg ✅ ✅ ✅*
ADTS ✅ ✅ ✅

*Sample number (absolute granule position) of Ogg depends on underlying codec implementing it.
