Wavecutter

Wavecutter detects silence and transcribes your audio to automatically create chapters at the right points. Adjust the silence threshold to get the splits exactly where you want them, or create equal-length chapters manually.

• Supports mp4, mp3, and m4b files
• Automatically finds silence in audio files and splits at those points
• Transcribes the segments to get missing chapters, or get titles based on the audio
• Manually create equal-length chapters
• Custom chapter titles, manually split individual chapters
• Select and merge chapters together
• Preview any chapter before exporting
• Export as M4A or MP3, individually or as a ZIP
• Handles iCloud Drive downloads

Works well for podcasts, audiobooks, lectures, recordings — anything long that needs splitting up.
