# Isolate Dialogue from Film Audio

Film audio is a complex mix of dialogue, music, sound effects, and ambient sound. In post-production, editors sometimes need to isolate the dialogue track -- for foreign language dubbing, accessibility subtitling, ADR reference, or to rebalance the mix. When the original multitrack session is unavailable, this was historically impossible.

AI audio isolation can extract dialogue from a final film mix with impressive accuracy. The technology distinguishes speech from music and effects even in action-heavy scenes, producing a clean dialogue track that can be used for translation, subtitling, or remix purposes.

This is valuable for localization teams working with finished films, content creators repurposing video dialogue, accessibility teams creating audio descriptions, and editors who need to adjust dialogue levels in a mixed-down file. When you only have the final mix, AI separation gives you back the individual components.
