Quick answers

Frequently asked questions

How do I choose the part of an audio clip to keep?

Set start and end times within the loaded clip, process it, then preview and export the cut as a new file.

Does trimming change the original recording?

No. Matrix processes a local copy and downloads a new result. Keep the original if you may need the removed section later.
