What Voxdub does differently

Everything runs online, no installation

Voxdub works right in your browser (Chrome, Firefox, Safari, Edge) — no installation, no studio setup. A desktop version (macOS and Windows) is available too. You create an account, import your video, and start working. For an adapter working from home or a voice actor who wants to practise without heavy gear, that's a real difference.

Recording is built in

Record voice directly in the app, with real-time noise reduction and monitoring, then export to BWF — the standard format for dubbing studios. You go from writing the rythmo band to recording the voice without switching tools.

Built for the whole dubbing chain

Video import, automatic loop detection and segmentation, writing and timing the text, rythmo calligraphy marks, recording, then export: adapters, audiovisual translators and voice actors all work on the same platform, from the first import to final delivery.

Exports in industry-standard formats

Voxdub exports to BWF, DETX, SRT, ASS, plus HD and 4K 60 fps video — everything you need to slot into an existing production pipeline without friction.

A 7-day free trial to get started

Voxdub offers a 7-day free trial, no commitment. The Pro plan is €12.99/mo or €99/yr for unlimited projects, subtitle translation, the AI voice mockup, studio mode and 4K export. You test everything before you pay.

Which tool for which profile?

Independent adapter / dubbing writer

Voxdub — write and time your rythmo bands online, from anywhere, without a studio licence.

Voice actor who wants to practise or record at home

Voxdub — built-in recording with noise reduction, no studio gear needed.

Studio with a workflow already built on Synchronos

Synchronos may still be relevant — test Voxdub alongside it on one project before migrating.

When Synchronos is still relevant

Let's be honest: if you already have a studio workflow fully built around Synchronos and its specifics, migrating has a cost. The smart move is to test an alternative on a real project before deciding — which is exactly why Voxdub offers a 7-day free trial.
