Frequently asked questions

Can I select cut points while listening?
Yes. Move the audio playhead and use the start or end button to capture its exact position.
Does cutting reduce audio quality?
The selected section is encoded at the bitrate you choose. Use the source bitrate or a high setting when quality matters.
Is my MP3 kept permanently?
No. Uploads and generated clips expire automatically after the administrator-set retention period.
