Dtas 0.6.0 - duct tape audio suite for *nix

Free Software command-line tools for audio playback, mastering, and
whatever else related to audio. dtas follows the worse-is-better
philosophy and acts as duct tape to combine existing command-line tools
for flexibility and ease-of-development. dtas is currently implemented
in Ruby (and some embedded shell), but may use other languages in the

Changes since 0.5.0 - player tracklist fixes/improvements

  • dtas-player - many fixes to tracklist handling
    Also minor syscall reduction and a fix for non-Linux-splice users.

  • the “dtas-tl reto” subcommand also works somewhat sanely, now.

There’s also a bunch of work-in-progress code that’s definitely not
ready for prime time and will change a lot. I’m just making this
release because the work-in-progress stuff is completely orthogonal
to the mostly-working stuff, and dtas has users other than myself

dtas is going in several different directions related to audio, not just
playback. My immediate focus will probably be on audio editing and
hopefully 0.7.0 will have more of that[1]. Of course, critical fixes to
components people actually use will take priority (but I think
dtas-player is solid, by now.

  • dtas-partstats - initial partitioning wrapper to the sox stats effect
    See commit 4f1a73ed584f0f74d6b32241f02ae871f3415f4a for details.
    This works, but could use some documentation…

There’s also some stuff which is completely not wired up outside
of internal unit tests, but will hopefully be ready in 0.7.0
