       Ecatools are simple command line utils that do various audio processing
       tasks. Most of them support batch processing. They all use ecasound  to
       do the actual audio processing work.


       A  tool  for converting a set of files to a common target format.  This
       target format is given as the first command line argument, and its syn-
       tax is .ext.


       A simple command-line tool for fixing DC-offset.


       See the separate ecalength(1) man page.


       Ecamonitor is a util program that can be used to monitor an active eca-
       sound session. Ecamonitor is able to show information about the current
       chainsetup  such as list of inputs, outputs, current position, effects,
       the engine status and numerous other things.

       By default ecamonitor will try to connect to IP4  address  "localhost",
       to  port  "2868".   A  different address can be specified when starting
       ecamonitor, for example "ecamonitor"  or  "ecamonitor".

       To  enable  inbound  connections,  ecasound  has to be started with the
       --daemon option. Ecamonitor is implemented in Python using  the  NetECI

       ified in ~/.ecasoundrc. Note! You can abort  ecaplay  at  any  time  by
       pressing  Ctrl-C. If you are playing multiple files, this will stop the
       current file and begin playing the next one. If you want to abort play-
       ing  immediately  instead  of  skipping  to the next file, press Ctrl-C
       twice in short succession (around one second).

              Set libecasound debug level. See ecasound(1).

       -h     Print usage information and exit.

              Skip “number“ of files.

              Use “output_device“ instead of the  default  output  device  (as
              specified in ~/.ecasoundrc.


       Ecasignalview is meant for monitoring signal amplitude and peak statis-
       tics. It accepts the following options:

       input  The first option not starting with a “-“ is interpreted as input
              string.  This  can  be  a device or a filename. All formats sup-
              ported 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“.

              Buffersize in sample frames. Defaults to 128.

       -c     Enable  cumulative mode. Counters are not reseted after refresh.

       -d     Enable debug mode.

              Specify default audio format. See ecasound(1) for details.

              Specify screen refresh rate in milliseconds.

       ~/.ecasound/ecasoundrc The default ecasound  resource  file.  See  eca-
       soundrc(5) for details.
