Overlap Separator

Overlapping audio
transcription separator.

Refine & export

Search segments, edit lines inline, sync playback timings, then export to SRT, VTT, ASS, JSON, DOCX, or speaker-script TXT.

Overlapping audio FAQs

How does the tool handle heavy crosstalk?+

It assigns the dominant speaker per slice and flags overlap regions so an editor can decide whether to keep, drop, or merge.

Will overlap markers appear in exports?+

Yes — JSON exports include overlap flags. Subtitle exports default to the dominant speaker per cue.

Does the separator work on conference call audio?+

Yes. The 'three people talking at once' scenario is exactly what it's tuned for.

Can I fine-tune overlap behaviour?+

Yes — the Studio lets you split overlap regions into separate cues or keep them as a single attributed line.
