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 0.3.0:

dtas 0.4.0 - dtas-splitfx, tracklist in -player

There is a new dtas-splitfx command intended for splitting up
single-track recordings into multiple tracks and applying
effects/comments to each of them.  It was made for splitting recordings
of vinyl records and live concert recordings.  dtas-splitfx is
independent of dtas-player (but shares some code/conventions).

The dtas-player also gains tracklist support (based on the MPRIS 2.0
spec).  This is another step toward having an MPRIS 2.0-compliant
interface.  There is a "dtas-tl" command helper for using/testing
tracklist functionality.  This helper may be folded into a higher-level
client soon, so it is not recommended as a a stable interface.

There are also some minor bugfixes in dtas-player.
