# Can the music be built to fit my episode automatically?

The length, yes. When you generate a background bed, the Match chip in the Length row sets the track to your episode’s duration, instead of you guessing a length and hoping it fits.

**Where:** Generate page → Length → Match.

A fast way to a finished episode: clean up the speech first, then generate the bed at Match length — it comes back sized to the result.
