How splitting works
- Points on the waveform: Add a split point at the playhead, then drag it or move it with the arrow keys. Each point divides the recording, so three points make four parts.
- Every part is checked: Each part is encoded and checked before it is offered. Parts are at least 0.1 second long, and a split makes up to 99 of them.
- One by one or all together: Download a single part, or all of them in one ZIP file. The original recording stays as it is.
Frequently asked questions
Are the parts exactly back to back?
Yes: each part ends at the sample where the next one starts. An MP3 part adds the few milliseconds of encoder delay every MP3 has; WAV adds none.
How are the parts named?
After the recording, numbered in order: interview-part-01.mp3, interview-part-02.mp3 and so on.
Can I split a video?
Its sound, yes: drop the video and extract its audio first, keep working with the recording, then split it.
