MacDub 0.4.1

Live translation (beta)

A new section under Dubbing: talk with people in another language through Google Meet, Zoom or any call app.

• What you say reaches them translated, in the voice you choose — your own Personal Voice included — through a virtual microphone.
• What they say reaches your headphones in your language, with the original turned down.
• About 1.8 s from the end of a sentence to its translated voice (measured on an M1): two SpeechAnalyzers run at once with fast results, and each sentence is closed at a 0.5 s pause.
• Chat-style view: a "…" bubble while someone speaks, and for every sentence its transcription · audio · total times.
• Pick the microphone, the languages (those on your Mac first, 👤 where your Personal Voice speaks), and a voice for each side.
• The virtual microphone is BlackHole (free, open source): MacDub installs it with one click, Homebrew included if needed.

Needs macOS 26 or later and headphones.

Google Meet extension

Settings › Extensions › Install in Chrome…

• Switches Meet's microphone to the translated voice by itself while live translation runs, and gives yours back when it stops. Meet's mute is always respected.
• Can post your translation in the meeting chat, and translates the chat messages the others write.
• Talks only to MacDub on your Mac (127.0.0.1).

Until it is in the Chrome Web Store it installs in developer mode: the steps are in Settings › Extensions. After updating MacDub, press ↻ on the extension's card in chrome://extensions.

History

• Dubbing and Live translation tabs.
• Conversations are saved with who said what, their timings, and both sides' audio in one take. Play them back, tap a sentence to jump to it, and export them as audio + subtitles, .srt, .md or .txt — each line says who spoke.
• Your earlier sessions open as before.
