AI Audio Tools
AI Video Dubbing Generator
Dubbing a locked edit has one hard requirement: the line has to land when the picture says it lands. Most AI voice tools generate audio at whatever pace they choose, leaving you to stretch, trim, or re-cut around it.
SeedAudio lets you pin a line to a time window. Write the start and end for each line and the model fits its pacing and pauses into that window, so the voice track drops onto an already-locked sequence. Multiple characters, background music, and sound effects all come out of the same pass.

How it works
- 1
Write your lines in the script editor, one row per line of dialogue.
- 2
Set a start (and optionally an end) time on each line to match your edit.
- 3
Generate — the delivery is paced to hit those windows, mixed with any music and effects you described.
Lines pinned to timecodes
Give a line a time window and the model paces it to fit, rather than deciding the rhythm for you. In our testing a line targeted at 7.0s landed at 7.2s.
Every character in one pass
Dub a whole scene at once — each character keeps a distinct, consistent voice across the clip, so you are not stitching separate exports together.
Score and foley included
Describe the music bed and the sound effects alongside the dialogue and they are generated and balanced together, not layered afterwards.
FAQ
- How accurate is the timing?
- In our own measurements a line targeted at a given second lands within roughly a second of it, and often much closer. Treat it as tight pacing rather than frame-accurate sync: check the result against your edit before locking.
- Can I dub more than one character in the same clip?
- Yes. Add a character per voice in the script editor and write their lines; they are all generated together in one pass with distinct voices.
- How long can one dub be?
- A single generation runs up to about two minutes. Longer scripts are split into linked segments automatically, with each segment referencing the previous one so the voice stays consistent.
- Do I need to upload my video?
- No. You work from your timecodes — write the start times your edit needs and generate the audio track to drop back in.
