Frequently Asked Questions

Can I fade in or out at cut points?
The web cutter exports clean hard cuts for speed. Add crossfades and fades in Seer Audio when you need polished transitions.
Does trimming re-encode my audio?
When format stays the same, SeerKits may stream-copy segments to avoid generation loss. Format changes apply a high-quality encode.
Is there a length limit on the source file?
Free web cuts support files up to 100 MB. Long-form podcast editing is better suited to Seer Audio on desktop.
