About

audacity-bridge is a command-line interface for Audacity with the mod-script-pipe module installed and enabled. Unlike the mod-script-pipe module, which only creates two communication pipes at Audacity startup, the audacity-bridge script also handles starting up and shutting down Audacity, which makes it useful for incorporating Audacity into batch scripts and make recipes.

The aupexport script converts AUdacity Project (AUP) files to any audio file format understood by Audacity; it also showcases the use of the audacity-bridge script.

Known Issues

1. Although the audacity-bridge script operates without user intervention, it isn't headless – i.e. a running X server is still required on unices.
2. The mod-script-pipe interface is blind and therefore brittle. Suppose a modal dialogue pops up, when Audacity starts up (f.ex. an orphaned files warning). This dialogue prevents the project file from being loaded, but the audacity-bridge client has limited means of detecting this.
3. While the Audacity splash screen is displayed, incoming messages are silently gobbled. This is handled by adding a fixed sleep at the beginning of the script, but this solution is brittle.
4. Upon receiving the Exit MenuCommand, Audacity crashes at Linux. The audacity-bridge script handles this internally, so no action is required on the part of the user.
