dtas - 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 future.

Primary executables available are:

dtas-player - gapless music player (or pipeline/process manager :P)
dtas-cueedit - embedded cuesheet editor (FLAC-only for now)

The centerpiece is dtas-player, a gapless music player designed to aid in writing scripts for sox/ecasound use. Unlike monolithic music players, dtas-player is close to a *nix shell in functionality, allowing for the execution of arbitrary commands as sources, filters, and sinks for audio. dtas-player supports:

any DSP effects offered by SoX, ecasound, LADSPA, LV2, etc..
multiple outputs for playback (including dumping audio to files or piping to arbitrary commands)
ReplayGain (including fallback gain and peak normalization)

dtas-player is a *nix pipeline and process manager. It may be used spawn and pipe to abitrary Unix commands, not just audio-related commands. It can interactively restart/replace the source (audio decoder) component of a pipeline while keeping the sink (playback endpoint) running.

Users of dtas-player will also be interested in the following scripts:

dtas-ctl - “raw” command-line scripting interface for dtas-player
dtas-enq - enqueue files/commands for dtas-player
dtas-msinkctl - enable/disable multiple sinks with one command
dtas-console - rudimentary curses interface for dtas-player
dtas-sinkedit - edit sinks (playback targets) for dtas-player
dtas-sourceedit - edit source (decoder process parameters) for dtas-player
dtas-xdelay - alternative sink for dtas-player

All scripts have some documentation in the Documentation/ directory or manpages distributed with the gem. dtas exposes no public APIs outside of command-line and YAML text. dtas is aimed at users familiar with the *nix command-line and editing text files. Familiarity with the Ruby programming language is absolutely NOT required.

Coming:

MPRIS/MPRIS 2.0 bridge for partial dtas-player control
tracklist support in dtas-player (maybe?)
whatever command-line tools come to mind…
native ffmpeg/avconv/gst support in dtas-player
better error handling, many bugfixes, etc…
better documentation
