<h2> Multimedia software</h2>
<h2>22.03.2009</h2>
<p>
<h2>NAME</h2>ecasoundrc - ecasound rcfile
<p>
<h2>SYNOPSIS</h2>
{prefix}/share/ecasound/ecasoundrc (for instance '/usr/local/share/ecasound/ecasoundrc')
$HOME/.ecasound/ecasoundrc
<p>
<h2>DESCRIPTION</h2>
<p>
<strong>ecasoundrc</strong> 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 <strong>-R</strong> option).
<p>
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).
<p>
<h2>VARIABLES</h2>
<p>
<dl>
<p>
<p><dt><strong>midi-device</strong><dd>
MIDI-device. If the device name is given in <em>rawmidi,/dev/midi*</em>
format, OSS/Linux or OSS/Lite drivers are used.
Device <em>rawmidi,/dev/snd/midiCxDy</em> 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 <em>rawmidi,/dev/midi</em>.
<p>
<p><dt><strong>default-output</strong><dd>
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 <em>autodetect</em>.
<p>
<p><dt><strong>default-audio-format</strong><dd>
Default values for sample format, channel count, sampling rate
and channel interleaving. Syntax is the same as used by
ecasound's <em>-f</em> option (see ecasound (1)).
Defaults to <em>s16_le,2,44100,i</em>.
<p>
<p><dt><strong>default-to-precise-sample-rates</strong><dd>
Whether to ignore sample rate differences (and possibly avoid
resampling). Currently only affects OSS-devices. Defaults to <em>false</em>.
<p>
<p><dt><strong>default-mix-mode</strong><dd>
If <em>default-mix-mode</em> is <em>sum</em>, engine will mix multiple channels into
one output channel by summing all input channels. In mode <em>avg</em>,
mixing is done by taking the average of all input channels. The
<em>avg</em> mode is safe from clipping, while <em>sum</em> is closer
to the way analog mixers work. Defaults to <em>avg</em>.
<p>
<p><dt><strong>bmode-defaults-nonrt</strong><dd>
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
<em>1024,false,50,false,100000,true</em>.
<p>
<p><dt><strong>bmode-defaults-rt</strong><dd>
See 'bmode-defaults-nonrt'. Defaults to
<em>1024,true,50,true,100000,true</em>.
<p>
<p><dt><strong>bmode-defaults-rtlowlatency</strong><dd>
See 'bmode-defaults-nonrt'. Defaults to
<em>256,true,50,true,100000,false</em>.
<p>
<p><dt><strong>resource-directory</strong><dd>
Directory for global ecasound configuration files.
Defaults to <em>{prefix-dir}/share/ecasound</em>.
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'.
<p>
<p><dt><strong>resource-file-genosc-envelopes</strong><dd>
Configuration file for generic oscillators. Is located in the
resource directory. Defaults to <em>generic_oscillators</em>.
<p>
<p><dt><strong>resource-file-effect-presets</strong><dd>
Configuration file for effect presets. Is located in the
resource directory. Defaults to <em>effect_presets</em>.
<p>
<p><dt><strong>ladspa-plugin-directory</strong><dd>
Directory containing LADSPA effect plugins. Defaults to <em>{prefix-dir}/lib/ladspa</em>.
If environment variable <em>LADSPA_PATH</em> exists, directories
specified in it are automatically searched for plugins.
Note! To match the syntax of the <em>LADSPA_PATH</em> environment
variable, 'ladspa-plugin-directory' can contain multiple
directories, separated by ':' characters.
<p>
<p><dt><strong>ext-cmd-text-editor</strong><dd>
If <em>ext-cmd-text-editor-use-getenv</em> is <em>false</em> or "EDITOR"
is null, value of this field is used.
<p>
<p><dt><strong>ext-cmd-text-editor-use-getenv</strong><dd>
Should ecasound try to query environment variable "EDITOR".
Defaults to <em>true</em>.
<p>
<p><dt><strong>ext-cmd-mp3-input</strong><dd>
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, <em>mpg123</em> is launched.
<p>
<p><dt><strong>ext-cmd-mp3-output</strong><dd>
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 <em>lame</em>. 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.
<p>
<p><dt><strong>ext-cmd-ogg-input</strong><dd>
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).
<p>
<p><dt><strong>ext-cmd-ogg-output</strong><dd>
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).
<p>
<p><dt><strong>ext-cmd-mikmod</strong><dd>
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
<em>mikmod</em>.
<p>
<p><dt><strong>ext-cmd-timidity</strong><dd>
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 <em>timidity</em>.
<p>
<p><dt><strong>ext-cmd-flac-input</strong><dd>
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).
<p>
<p><dt><strong>ext-cmd-flac-output</strong><dd>
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).
<p>
<p><dt><strong>ext-cmd-aac-input</strong><dd>
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 <em>faad</em>.
<p>
<p><dt><strong>ext-cmd-aac-output</strong><dd>
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
<em>faac</em>.
