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.
Human voices, your own performance
Voxdub is built for people who dub with their own voice. The final dub is your performance as a voice actor, in the spirit of #TouchePasMaVF. You record your lines following the rythmo band, with built-in noise reduction for a clean result.
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 video up to 120 fps, everything you need to slot into an existing production pipeline without friction.
A 7-day trial to get started
Voxdub offers a 7-day trial, no commitment. The Pro plan is €12.99/mo or €99/yr for unlimited projects, subtitle translation, studio mode and 4K export. You test everything before you pay.

When Synchora is still relevant
Synchora has real strengths. It is a desktop application for Windows, macOS and Linux, and your projects stay in local files. Synchora has a free plan with no time limit. It adds French spelling and grammar checks, fee sheets (Pro plan) and series management. If these points matter most to you, Synchora is a good fit.
