ecamegapedal - real-time effect processor


ecamegapedal [options] [<input> <output>]


Ecamegapedal is a real-time effect processor software with a graphical user interface for controlling the effect parameters. It is meant to be used as a virtual guitar-fx or studio effect box. In addition to real-time operation, Ecamegapedal also supports reading from and writing to audio files. All audio object and effect plugin types provided by the Ecasound libraries are supported. This includes ALSA, JACK, OSS, aRts, over 20 file formats, over 30 effect types, LADSPA plugins and multi-operator effect presets. Ecamegapedal's implementation is based on Ecasound and Qt libraries.


First argument, <input>, sets the device or file, from which Ecamegapedal will read audio data. The syntax is identical to the one used by Ecasound (see ecasound(1)). Some examples:

Read from RIFF WAVE audio file 'foo.wav'.
Record from ALSA soundcard 'default'.
Record from OSS soundcard '/dev/dsp'.
Connect to a JACK server and register a JACK input port for Ecamegapedal.
Read from MP3 audio file 'foo.mp3'.
And so on, see ecasound(1) and the online documentation at for more info about object types.

The second argument, <output>, sets the output device or file to which Ecamegapedal should write audio data. Syntax is the same as for <input>.

Note! These instructions also apply when modifying the input and output objects using from the user-interface.

One design goal has been that Ecamegapedal can be used without a mouse. In practise this means that shortcuts work everywhere, and all pushbuttons and other controls have a textual description.

Ecamegapedal makes use of both accelerator keys and shortcut keys. These are defined as follows:

An accelerator key is an alphanumeric key that can be pressed together with a Meta-key, usually Alt, to select an item which is visible on the screen. If an item has an accelerator key, this is shown by underlining that character.

A shortcut key is a combination of Ctrl and another key. When pressed together they start an action from any of the menus. In the menu, the shortcut is printed after each item so that the user can learn about the shortcuts by using the application.

In Ecamegapedal, transport controls (start, stop) play can be accessed using shortcuts (ie. ctrl-t, ctrl-s, .. instead of alt-t, alt-s).


~/.ecasound/ecasoundrc User-specific setting that control ecasound operation. These settings also affect ecamegapedal sessions. See ecasoundrc(5) for more information.
