Chapters are the difference between "a 74-minute file" and "a navigable episode." They feed three things at once: in-app chapter navigation, the timestamp list in your show notes, and the supply of short clips that actually market the show. One cutting session produces all three.
Where chapters actually belong
Cut at topic boundaries, not time intervals. Nobody wants "Chapter 4 (30:00–40:00)"; they want "Chapter 4 — The pricing mistake." Practical boundary markers in a typical episode:
- The end of the cold open / start of the intro music
- Each major question or topic shift in an interview
- Ad breaks (cut on both sides — you'll thank yourself when re-inserting or removing ads later)
- The start of the outro/CTA
A 60–80 minute conversation usually yields 6–10 chapters. More than that fragments the listening experience; fewer means chapters too long to navigate.
The cutting session
- Drop the episode file on the audio splitter — an exported MP3 or your original WAV both work.
- Skim the waveform: intro music, laughter, and ad reads all have recognizable shapes, and long pauses (often topic transitions) show as flat gaps. Cut at silences can rough in markers at those pauses; then adjust by adding the markers detection missed.
- Click to place a marker at each chapter boundary. Use each segment's Play button to confirm the cut lands in the breath before the new topic, not mid-sentence.
- Note the segment table: every track row shows its start → end timestamps. This table is your show-notes chapter list — copy the start times next to your chapter titles and you're done with timestamps.
- Export the ZIP: one clean WAV per chapter, numbered in order.
What to do with the pieces
Show notes & apps. Paste the timestamp list into your episode description (00:00 Intro / 06:42 Origin story / 21:15 The pricing mistake…). YouTube converts these into tappable chapter markers automatically; podcast apps display them from the notes.
Social clips. The best 60–90 seconds of each chapter is a candidate clip. Because each chapter is its own file, finding that moment means scrubbing a 7-minute file, not a 74-minute one. Pair with a waveform video or feed it into your video clipping workflow if you record on camera.
Repackaging. Chapters are editorial atoms: compile "every listener question from season 2" or cut a tight 25-minute edit for a feed swap — trivial when the source is already segmented.
Format note
Chapters export as 16-bit WAV — lossless from your source, ideal as editing material. Encode to MP3 only at the final publishing step, once, so your clips never stack compression generations. (Details: WAV vs MP3.)
Unpublished episodes stay private by architecture: the splitter never uploads them anywhere.
