Visecas

Introduction

Visecas is a graphical user interface for Ecasound (http://eca.cx/ecasound), a software package written by Kai Vehmanen (k@eca.cx) which is designed for multitrack audio processing. It starts Ecasound as a child process and communicates via a pipe using Ecasound's InterActive Mode (IAM) commands.

If you don't know anything about Ecasound please visit Ecasound's examples page and read it's user guide.

Visecas has been designed with GNOME's Human Interface Guidelines in mind.

Download

Please visit Visecas' sourceforge project page to download the latest release. Make sure that the dependencies are fulfilled (see below).

CVS

Sourceforge currently is a little bit confused regarding statistics.
Although they seem to think the project's cvs repository is untouched Visecas' module is in there.
If you are interested in cutting edge bugfixes and features you can check it out in the usual sourceforge way:

cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/visecas login
cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/visecas co visecas

You can also browse the repository.

• Single Document Interface (one toplevel window per chainsetup).
• Ecasound's status (engine status, chainsetup validity, position, etc.) is displayed.
• Chains can be added, removed, renamed, muted and bypassed.
• Audio objects can be added, removed and attached to chains.
