NAME

ecasoundrc - ecasound rcfile

SYNOPSIS

{prefix}/share/ecasound/ecasoundrc (for instance '/usr/local/share/ecasound/ecasoundrc') $HOME/.ecasound/ecasoundrc

DESCRIPTION

ecasoundrc is the main configuration file for ecasound. Any user-specific modification should be done to $HOME/.ecasound/ecasoundrc, not to the global resource file. Ecasound also allows one to disable the normal policy and only read from a specific resource file (see ecasound (1) and documentation for the -R option).

The format is quite simple. One line consists of a configuration variable and its value. Variable and value are separated with either '=' or ' '. Lines beginning with a "#" are ignored (comment lines).

VARIABLES

midi-device
MIDI-device. If the device name is given in rawmidi,/dev/midi* format, OSS/Linux or OSS/Lite drivers are used. Device rawmidi,/dev/snd/midiCxDy opens an ALSA raw-MIDI device with card number 'x' and device number 'y'. See ecasound (1) man page (the '-Md option) for more info. Defaults to rawmidi,/dev/midi.

default-output
Output device to use by default. If a chainsetup with zero outputs, but with one or more inputs, is connected, a default output is added and all the chains are connected to it. If the special-case value 'autodetect' is specified, ecasound will try to auto-detect a suitable device (JACK -> ALSA -> OSS -> rtnull). Defaults to autodetect.

default-audio-format
Default values for sample format, channel count, sampling rate and channel interleaving. Syntax is the same as used by ecasound's -f option (see ecasound (1)). Defaults to s16_le,2,44100,i.

default-to-precise-sample-rates
Whether to ignore sample rate differences (and possibly avoid resampling). Currently only affects OSS-devices. Defaults to false.

default-mix-mode
If default-mix-mode is sum, engine will mix multiple channels into one output channel by summing all input channels. In mode avg, mixing is done by taking the average of all input channels. The avg mode is safe from clipping, while sum is closer to the way analog mixers work. Defaults to avg.

bmode-defaults-nonrt
Selects the default parameters to use with buffering mode 'nonrt' (other modes are 'rt' and 'rtlowlatency). Parameters are given as a comma-separated tuple of values: 1) buffersize (number,-b), 2) raised priority (true/false,-r), 3) sched_priority (number,-r:X), 4) double buffering (true/false,-z:db), 5) db-bufsize (number,-z:db,X), and 6) max intbuf (true/false,-z:intbuf). Defaults to 1024,false,50,false,100000,true.

bmode-defaults-rt
See 'bmode-defaults-nonrt'. Defaults to 1024,true,50,true,100000,true.

bmode-defaults-rtlowlatency
See 'bmode-defaults-nonrt'. Defaults to 256,true,50,true,100000,false.

resource-directory
Directory for global ecasound configuration files. Defaults to {prefix-dir}/share/ecasound. Note! User-specific resource files can be be stored to '$(HOME)/.ecasound/'. For instance you can add your own presets definitions to '$(HOME)/.ecasound/effect_presets'.

resource-file-genosc-envelopes
Configuration file for generic oscillators. Is located in the resource directory. Defaults to generic_oscillators.

resource-file-effect-presets
Configuration file for effect presets. Is located in the resource directory. Defaults to effect_presets.

ladspa-plugin-directory
Directory containing LADSPA effect plugins. Defaults to {prefix-dir}/lib/ladspa. If environment variable LADSPA_PATH exists, directories specified in it are automatically searched for plugins. Note! To match the syntax of the LADSPA_PATH environment variable, 'ladspa-plugin-directory' can contain multiple directories, separated by ':' characters.

ext-cmd-text-editor
If ext-cmd-text-editor-use-getenv is false or "EDITOR" is null, value of this field is used.

ext-cmd-text-editor-use-getenv
Should ecasound try to query environment variable "EDITOR". Defaults to true.

ext-cmd-mp3-input
Command for starting mp3 input. Ecasound expects to read signed, 16bit, little-endian stereo audio samples from its standard input. Ecsound will query other audio format parameters by parsing the mp3 file header. Before execution, %f is replaced with path to the input mp3. If exists, "%o" is replaced with he start offset in mp3 frames. Double-quotes and backslash-espacing can be used to include white-space to individual parameters. By default, mpg123 is launched.

ext-cmd-mp3-output
Command for starting mp3 output. Ecasound will write stereo, signed, 16bit, little-endian samples to standard output. Sample rate is configurable. Before execution, %f is replaced with path to the output mp3, %S with sample rate in kHz, and %B with encoding bitrate in kbps. Double-quotes and backslash-espacing can be used to include white-space to individual parameters. By default Ecasound will try to launch lame. As a special exception (added to Ecasound 2.7.0), if the output program is "lame" and options include "--big-endian", Ecasound will detect this and output big-endian samples.

ext-cmd-ogg-input
Command for starting Ogg Vorbis input. Ecasound expects that audio samples are written to standard output. It should be noted that Ecasound is not able to query the audio format parameters from ogg files, so these need to be set manually by the user. Before execution, %f is replaced with path to the input ogg. Double-quotes and backslash-espacing can be used to include white-space to individual parameters. By default Ecasound will try to launch (ogg123).

ext-cmd-ogg-output
Command for starting Ogg Vorbis output. Ecasound will write samples in little-endian format to standard output. Other audio parameters are configurable. Before execution, %f is replaced with path to the output ogg, %c, %s and %b with matching audio format parameters, and %B with encoding bitrate in kbps. Double-quotes and backslash-espacing can be used to include white-space to individual parameters. By default Ecasound will try to launch (oggenc).

ext-cmd-mikmod
Command for starting mikmod input. Ecasound expects that signed, 16bit, stereo audio samples are written to standard output. Before execution, %f is replaced with file path, and %s with selected sample rate. Double-quotes and backslash-espacing can be used to include white-space to individual parameters. By default Ecasound will try to launch mikmod.

ext-cmd-timidity
Command for starting timidity++ input. Ecasound expects that signed, 16bit, stereo audio samples are written to standard output. Before execution, %f is replaced with file path, and %s with sample rate. Double-quotes and backslash-espacing can be used to include white-space to individual parameters. By default Ecasound will try to launch timidity.

ext-cmd-flac-input
Command for starting FLAC input. Ecasound expects that audio samples are written to standard output. It should be noted that Ecasound is not able to query the audio format parameters from FLAC files, so these need to be set manually by the user. Before execution, %f is replaced with path to the input FLAC file. Double-quotes and backslash-espacing can be used to include white-space to individual parameters. By default Ecasound will try to launch (flac).

ext-cmd-flac-output
Command for starting FLAC output. Ecasound will write samples to standard output. All audio parameters are configurable. Before execution, %f is replaced with path to the output flac, %c, %b and %s with matching audio format parameters, %I with either 'signed' or 'unsigned', and %E with either 'little' or 'big'. Double-quotes and backslash-espacing can be used to include white-space to individual parameters. By default Ecasound will try to launch (flac).

ext-cmd-aac-input
Command for starting AAC input. Ecasound expects that signed, 16bit, stereo, big-endian audio samplesare written to standard output. It should be noted that Ecasound is not able to query the input sample rate, so this needs to be set manually by the user. Before execution, %f is replaced with path to the input AAC file. Note! FAAC must be compiled with MP4 support. Double-quotes and backslash-espacing can be used to include white-space to individual parameters. By default Ecasound will try to laucnh faad.

ext-cmd-aac-output
Command for starting AAC output. Ecasound will write big-endian audio samples to standard output. All other audio parameters are configurable. Before execution, %f is replaced with path to the output AAC file, %c, %b and %s with matching audio format parameters. Note! FAAC must be compiled with MP4 support. Double-quotes and backslash-espacing can be used to include white-space to individual parameters. By default Ecasound will try to launch faac.
