|-d:debuglevel||Set libecasound debug level. See ecasound(1).|
|-f||Flush the playlist contents. See also options -l, -p and -q.|
|-h||Print usage information and exit.|
|-k:number||Skip number of files.|
|-l||List the current playlist contents to stdout. See also options -f, -p and -q.|
|-o:output_device||Use output_device instead of the default output device (as specified in ~/.ecasound/ecasoundrc). Syntax is same as used by -o ecasound option (see ecasound(1) man page). This option overrides the ECAPLAY_OUTPUT_DEVICE environment variable (more info below).|
|-p||Play tracks in the playlist (in looped mode). See also options -f, -l and -q.|
|-q||Queue new tracks to the playlist. All filenames given on the command-line will be added to the the playlist. It is possible to queue new tracks while another instance of ecaplay is using the playlist. See also options -f, -l and -p.|
|Ecasignalview is meant for monitoring signal amplitude and peak statistics. It accepts the following options:|
|input||The first option not starting with a - is interpreted as an input string. This can be a device or a filename. All formats supported by libecasound are accepted. Defaults to /dev/dsp.|
|output||Similarly to input, second option not starting with a - is interpreted as output. Defaults to null.|
|-b:buffersize||Buffersize in sample frames. Defaults to 128.|
|-c||Enable cumulative mode. Counters are not reseted after refresh. *deprecated*|
|-d||Enable debug mode.|
|-f:format_string||Specify default audio format. See ecasound(1) for details.|
|-r:rate_msec||Specify screen refresh rate in milliseconds.|
|-I||Use linear scale for showing audio sample amplitude.|
|-L||Use logarithmic scale for showing audio sample amplitude.|
|-G, -B, -M*, -r, -z||Ecasound options use to modify the engine behaviour, see ecasound(1) manpage for details.|
|When ecasignalview is running, the following keyboard commands can be used to control the operation (requires system support for UNIX terminal interface control):|
|spacebar||Reset statistics (max-peak, avg-amplitude and clipped samples count).|
|q or Q or Esc||Quit ecasignalview.|
|It is also possible to reset the max-peak and clipped-samples counters by sending a SIGHUP signal to the process (i.e. from another console: killall -v -HUP ecasignalview).|
ECASOUND Path to the ecasound executable. Used by many ecatools.
ECAPLAY_OUTPUT_DEVICE Device ecaplay should use for audio output. Same syntax as for ecaplay/ecasound -o option.
~/.ecasound/ecasoundrc The default ecasound resource file. See ecasoundrc(5) for details.
~/.ecasound/ecaplay_queue File used to store the ecaplay playlist (one track per line with full path).
