This can be useful with Live Caption Translator when you want to: - Caption system audio or other apps (beyond the current tab) - Send system audio into Zoom or Teams - Record desktop audio in OBS - Mix mic + music into one output - Capture app-specific sound Below are reliable tools and how to use them. On Windows, the two most common tools are: - **VB-Audio Virtual Cable (VB-CABLE)** — Free, simple virtual cable. Creates a virtual input/output pair so you can route audio between applications. - **Virtual Audio Cable (VAC)** — Commercial option with more routing flexibility. After installing, select the virtual output as your system playback device or route specific apps to it, then choose the virtual input as the microphone source in Live Caption (Microphone mode). On macOS, the most powerful and flexible solution is: - **Loopback** (by Rogue Amoeba) — Combines audio from multiple apps and devices into one virtual source. Lets you mix system audio, mic, and specific apps into a single input. --** Blackhole** After setting up Loopback, choose the Loopback device as your microphone in Live Caption (Microphone mode) to caption the routed audio.

Audio Transcription & Live Interpreter
Real-time transcription, live translation, and speech-to-speech playback for browser audio. Includes Subtitle TTS for videos. Audio Transcription is a powerful extension that turns your browser into a real-time interpreter. It captures any audio playing in a tab (transcribing it via Whisper AI) or reads existing video subtitles, translates them live, and reads the results back to you via Text-to-Speech (TTS). 🌟 Designed with privacy and efficiency in mind, it is optimized to run smoothly on low-resource computers and operates as independently from cloud services as possible. Compatible with Linux, Windows, and macOS, this extension acts as a true Live Interpreter for any media stream. • 🎬 Subtitle TTS Mode: Read aloud and translate existing subtitles from YouTube, Twitch, or any HTML5 video without needing a local server. • 🌐 Source Language Control: Rely on smart auto-detection, or manually select the subtitle language for maximum accuracy. • 🗣️ Real-Time Speech-to-Speech: Listen to live translations with a natural, fluid voice that buffers complete sentences for a seamless experience. • 📝 Live Audio Transcription: Fast and accurate transcription from scratch using your local machine's processing power with OpenAI's Whisper AI (WhisperLive server required). • 🤖 Instant Translation: Translate live text using Google Translate (free) or the latest Google Gemini (Flash-Lite) & Gemma 4 AI models. • 🖼️ Flexible UI Modes: View transcripts in a floating overlay or a dedicated Standalone popup window. • 🛡️ Total Privacy: Local audio processing and transparent open-source code. The Subtitle TTS mode works completely out-of-the-box. However, to use the advanced "Live Audio Transcription" feature, you must run the local WhisperLive server on your computer. Get the server scripts and detailed setup instructions at: https://github.com/antor44/Audio-Transcription This is a free and open-source project distributed under the GNU General Public License v3.0 (GPL-3.0). For more details, visit the GitHub repository. --- 🆕 WHAT'S NEW IN VERSION 3.1.0: • 🎤 Smart TTS: The voice engine now intelligently waits for sentence boundaries (periods), creating a much more natural and less choppy listening experience. • ⭐ Language Selector: Added an optional 'Source Language' menu in Subtitle TTS mode to fix auto-detection edge cases. • 🤖 AI Update: Cleaned up deprecated models and added support for the new Gemma 4 generation. • 🐞 Bug Fixes: Fixed initial auto-detect hangs, stopped short phrases from being skipped, and fixed the "Stop" button state when tabs are closed.
