Before: one long file
When silence detection is not the right fit
Use chunks when the output needs to be regular
Auto-cut is useful when the recording contains natural pauses. Chunk cutting is for jobs where regular structure matters more: transcription batches, ambience beds, long interviews, training audio, sample-library source captures, and collaborator handoffs.
You can split by duration, such as every 5 or 10 minutes, or by count, such as 12 equal files from one source recording. AudioMultiCut creates the segments first, so you can still inspect and adjust before exporting.
By time
Make 30-second, 5-minute, 10-minute, or precise millisecond chunks for review and processing.
By count
Ask for exactly 8, 12, 24, or 200 equal parts when the downstream system expects a fixed number of files.
From an edited template
Adjust one segment and use it as a forward template when the useful start point is not exactly at zero.
Examples that fit chunk cutting
Chunk cutting is deliberately mechanical. That is the point. It is best when you want uniform files and will do creative mapping, transcription, tagging, or review after the split.
