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.
INPUT/OUTPUT SYNTAX
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:
"foo.wav"
Read from RIFF WAVE audio file 'foo.wav'.
"alsa,default"
Record from ALSA soundcard 'default'.
"/dev/dsp"
Record from OSS soundcard '/dev/dsp'.
"jack"
Connect to a JACK server and register a JACK input port for
Ecamegapedal.
"foo.mp3"
Read from MP3 audio file 'foo.mp3'.
"..."
And so on, see ecasound(1) and the online documentation
at http://www.eca.cx/ecasound
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.
OPTIONS
"--help"
Show a small usage help screen.
"--version"
Print the version info.
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).
FILES
~/.ecasound/ecasoundrc
User-specific setting that control ecasound operation.
These settings also affect ecamegapedal sessions. See
ecasoundrc(5) for more information.
