jplay2

jack plays it all

jplay2 is a command-line audio player, gluing

it plays a single file (no playlist), but with ffmpeg & libsndfile it plays every file one throws at it (even DVD-vobs or timemachine-w64 ;-) ). Once started, it's only possible to interact with jplay2 via OSC or jack-transport.

Audio decoder:

  • libsndfile
  • ffmpeg
  • libquicktime

Features:

  • optional jack-transport
    • stop OR scrub audio (loop N frames) when jack-transport is paused
  • variable or fixed speed, resampling
  • cache decoded (and/or resampled) audio
    • LRU cache, read/decode ahead, resample JIT
