% dtas-env(7) dtas user manual % # NAME dtas-env - environment variables used through DTAS # DESCRIPTION As dtas uses Bourne shell and exposes it to users, dtas should have a cohesive set of common environment variables across its audio production and playback environments. This attempts to document them. Most of these environments are set and managed by dtas itself, but users editing commands (e.g. via dtas-sourcedit(1) should be aware of them. # ENVIRONMENT ECAFMT - an snippet of command-line switches for ecasound describing audio format parameters (such as word length, channels, sample rate), see dtas-player_protocol(7) for more info. (e.g. "-fs32_le,2,44100") INFILE - the primary input file for playback or processing. (e.g. "/path/to/ex.flac") RGFX - the sox effect used for applying ReplayGain compensation. Only used during playback in dtas-player. (e.g. "gain -6.0"). Removing this prevents ReplayGain from working and may damage playback equipment with loudly mastered music. SOXFMT - an snippet of command-line switches for sox describing audio format parameters (such as word length, channels, sample rate), see dtas-player_protocol(7) for more info. (e.g. "-ts32 -c2 -r44100") TRIMFX - the sox effect used for seeking during playback with dtas-player and track offsets for dtas-splitfx. (e.g. "trim 36000s") Additionally, dtas-splitfx(1) documents more environment variables which are not used elsewhere. # ENVIRONMENT FOR OTHER EXECUTABLES By virtue of running other programs, dtas indirectly uses many commonly-accepted environment variables such as EDITOR / VISUAL for selecting a text editor, and SOX_OPTS, AUDIODEV, AUDIODRIVER for sox(1) and play(1) commands and LADSPA_PATH for anything using LADSPA plugins (including sox). The TMPDIR environment variable controls where temporary files are placed for most programs. # CONTACT All feedback welcome via plain-text mail to: \ Mailing list archives available at and \ No subscription is necessary to post to the mailing list. # COPYRIGHT Copyright 2015-2016 all contributors .\ License: GPL-3.0+
