Audacity is a powerful sound editor. In the course of using it, I have needed to split long speeches into tracks so that they are CD-friendly. Several existing plugins allow for this but there is no minimum length on the tracks.

Suppose that the speaker interacts with someone from the audience for a couple of minutes. Most silence-finding plugins would result in several dozen tracks during this relatively short exchange. In order to rectify the situation, we need the ability to define a minimum track length to go along with all of the other options.

I took some code from JMA (based on Alex S. Brown's work) and rewrote it to do what I needed. Along the way, I also implemented the recommendations from a follow-up post by stevethefiddle, which means that this plugin requires at least Audacity 1.3.

Save the Tracker.ny file to your Audacity plug-ins folder and restart Audacity. My edition appears under the "Analyze" menu as "Split into Tracks..."

Also available is the original script without my modifications, for anybody who is interested.
