# 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) * dtas-splitfx - split audio and apply effects to all tracks 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 arbitrary 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 * dtas-tl - command-line helpers for tracklist functionality in dtas-player All scripts have some documentation in the Documentation/ directory or manpages distributed with the gem. Documentation is also available on https://80x24.org/dtas/$COMMAND.txt in plain-text form. 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: * mpd (Music Player Daemon) bridge for partial dtas-player control * MPRIS/MPRIS 2.0 bridge for partial dtas-player control * whatever command-line tools come to mind... * better error handling, many bugfixes, etc... * better documentation ## Source code git clone https://80x24.org/dtas.git Please use git-format-patch(1) and git-send-email(1) distributed with the git(7) suite for generating and sending patches.
