Native audio: sound made with the picture
Native audio means a video model generates sound, voices and effects in the same pass as the picture, instead of adding them afterwards. From 3 source pages, read 2026-09-25; no maker pays to be listed.
PixVerse says its V6 model makes 1080p video with native audio. Story.com generates voices with the visuals from an uploaded screenplay, and Vidu names 16-second audio-visual generation.
Sound made with the picture tends to line up with it: a door closes when the sound says so.
It is harder to control. A voice generated inside a clip may not match the same character's voice in the next clip, which matters over a series.
Tools that keep a voice per character, or clone one, give more control at the cost of a separate step.
For dialogue-heavy episodes, check whether native audio can be switched off so a fixed voice can be used.
PixVerse also offers a separate lip-sync tool for voice and sound, which suits lines recorded or generated elsewhere; the two routes can be mixed within one episode, native sound for crowd scenes and a fixed voice for the lead.
Sound effects and ambience are where native audio helps most: footsteps, rain and doors that line up with the picture without a separate pass.

2From a series pipeline
The series side of “Native audio” looks like this in SceneMixer's own guides:
A SceneMixer segment comes out with its sound already in it: each line spoken in that character’s voice, the speaker’s lips moving with the words, and the ambience of the place — rain, traffic, a clock.

Voices are matched from a library of sampled preset voices, or supplied by you as an upload of your own audio.
