Goal and scope
Turn long podcasts, lectures, and recordings into precise clips, silence-based sections, chapters, and ordered delivery segments.
Use this guide to turn the stated scope into a reviewable result. Keep the source, intermediate outputs, and decisions together so the next person can understand what was checked and why.
Prepare evidence and make decisions
Prepare the original recording and note its duration.
Decide whether the output needs exact timestamps, natural pauses, chapters, or a fixed delivery length.
Decision: Which splitting path fits?. Use audio-split-at-timestamps for known edit points, audio-split-by-silence for natural pauses, and audio-label-split or audio-chapter-split when markers already exist. Choose audio-split-by-duration only when equal-length parts matter most.
Complete the workflow
1. Choose the cut map
Mark known points and decide whether pauses, labels, chapters, or equal durations provide the reliable structure. Use audio-split-at-timestamps, audio-split-by-silence, audio-split-by-duration.
2. Make precise trims
Remove unwanted material, extract a highlight, or trim the opening and closing while preserving the segment plan. Use audio-extract-segment, audio-remove-segment, audio-trim-from-start, audio-trim-to-end, audio-trim.
3. Create structured segments
Use chapter metadata or an Audacity-style label file when the recording already has editorial markers. Use audio-add-chapters, audio-chapter-split, audio-label-split.
4. Assemble delivery
Check short head and tail previews, then place or stitch clips into the requested order and spacing. Use audio-head, audio-tail, audio-sequence-builder, audio-stitcher.
Verify the result before handoff
- Each excerpt starts and ends at its planned boundary.
- Segments are clearly identified and ordered for delivery.
- The final boundaries and sequence can be checked against the source timeline.
Common questions
- When should I split by silence? Use it when pauses reliably separate speech and exact edit points are unavailable; review the thresholds because music and room tone can create unwanted boundaries.
- What is the difference between chapters and labels? Chapters are embedded navigation metadata, while labels are an external marker plan. Choose the splitter that matches the structure you already have.
- How do I make equal delivery parts? Use duration splitting when every part must meet a fixed length, then review boundaries and assemble the files if needed.
