===== jack plays it all =====

//jplay2// is a command-line audio player, gluing

  * [[http://jackaudio.org|JACK]]
  * [[http://www.mega-nerd.com/SRC/|libsamplerate]]
  * [[sf>liblo]] (OSC control)

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
