Plan the parts
Listen for natural stopping points and note the start and end of each part. For spoken material, avoid cutting a sentence or an answer across files. A simple naming scheme such as 01 Introduction and 02 Main topic keeps the parts in order.
Export one range at a time
- Add the long recording in Cut MP3 and open Trim clip.
- Set the range for your first part, preview both edges, and choose Apply trim.
- Choose a descriptive output name and click Export Cut.
- Return to Trim clip, set the next range, and export it with a different name. Repeat for the remaining parts.
Keep the divisions intentional
This is a manual range-and-export workflow. It does not automatically create a set of separate chapter files from one click.
Keep each finished part long enough to make sense on its own. If two adjacent parts should meet without a gap, use the same timestamp for the end of one and the start of the next.
Check the complete set
- Play the ending of each part and the opening of the following one.
- Confirm that the filenames sort into the intended sequence.
- Keep the long original until you have checked every exported part.
