00:00Hello everyone and welcome back.
00:05Today we're building a full localization pipeline.
00:10First, let's talk about why timing matters so much.
00:15If your voiceover runs long, the whole edit falls apart.
00:20So we lock every segment to the source timeline.

FINAL DURATION
10:24every track, to the frame

A recording is imported, transcribed, translated into Arabic, Spanish and French, voiced, and exported as three audio tracks all matching the original length.

    Export to your editor

    MP3 or WAV, every track locked to the original length. Drop and go.

Your computer
does the work.

No uploads, no queue, no per-minute bill. Auvio runs the whole pipeline locally, which means it's fast, private, and works with the wifi off. Nothing leaves your Mac.

Built for the edit, not the demo.

  • Fit to Timing

    One click shortens the translation, nudges the speed and trims the pauses until the segment lands on the source timeline.

  • Duration lock

    Turn it on and every exported track is exactly as long as your original. No re-syncing in the edit.

  • Multi-track review

    Stack every language against the original on one shared playhead and hear the difference immediately.

  • Real transcript editing

    Split, merge, retime and rewrite. Keyboard-driven, with undo that behaves like a pro app.

  • Works offline

    On a plane, in a studio basement, on hotel wifi. The pipeline never needs a connection.

  • Your media never moves

    Source files stay on the device you imported them on. Nothing is uploaded, ever.

Questions we get a lot.

Does this need an internet connection?
Only to download the app and the language models you choose. After that Auvio never needs a connection again — transcription, translation, voice generation, timing and export all run on your own machine.
Do I need an account?
No. There is nothing to sign in to and no server holding your work. Projects, models, voices and settings live on your Mac.
What do you collect?
Nothing. No audio, no video, no transcripts, no exports, no analytics. Your media never leaves the device it was imported on.
Is this voice cloning?
No. Auvio uses generated voices you pick from a library. It does not clone anyone, and it does not need a sample of your voice.
Do I have to re-render my video?
No. Auvio outputs audio tracks matched to your original timeline, so you drop them onto the timeline you already cut in Premiere, Final Cut, Resolve or CapCut.
Is it really one payment?
Yes. $49 once, updates included. There is no subscription to cancel and nothing that expires.
Which Macs does it run on?
macOS 13 or later on Apple Silicon. The models run on Metal, so an Intel Mac is not supported.

Every language.
Same timeline.

One payment. No account, no watermark, no metering.
