Chunk cutting

Split audio into equal chunks

Create predictable audio pieces when you already know the interval or the number of files you need. Split by minutes, seconds, milliseconds, or by total segment count.

Choose the chunking method

Upload a long recording and use Split into equal chunks in the editor. Choose a fixed duration or the exact number of parts you want.

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.
