How to use this audio tool

Cut a time range out of a supported audio file without uploading it.

How the audio logic works

  • Choose an audio file.
  • Enter start and end times in seconds.
  • FFmpeg creates a trimmed output file.

Formula

Output duration is approximately end time minus start time.

Example

Trim a 30-second clip from a longer recording.

Using the audio result

Use the output as a practical starting point, then review it before using it in an important workflow.

Assumptions and limitations

  • Frame-accurate results vary by codec.
  • For V1, keep files small for best browser reliability.
