Play any audio on your computer

Because WireLang™ Live runs natively, it captures all system output audio. Play a YouTube video in your browser, watch a video in VLC, join a Zoom or Teams call, or listen to a podcast in Spotify. Any audio playing through your speakers can be translated.

Pick your language and press Start

In the app, choose the target language you want to hear and click Start Translating. Within one to two seconds, the translated voice plays over the softened original audio.

Note: Set your target language to the language you want to hear (for example, choose Spanish when playing an English video).

Using the floating toolbar

When translation starts, the main window minimizes and a compact toolbar floats on screen. From left to right: the waveform (teal for live, amber while connecting), the language chip, the timer(elapsed time on BYO, remaining balance on Credits), CC for subtitles, the rec button to record audio, the speaker for volume controls, and pause / stop buttons. You can drag the toolbar anywhere or click the chevron to collapse it.

Balance the volumes

Click the speaker icon to open the audio menu. Voice volume sets how loud the translated voice plays (up to 200%). Source volume ducks the original audio underneath it. On Windows you can also pick a single app as theaudio source instead of the entire PC.

Switch languages mid-session

Click the language chip (such as "ES") and pick a new target from 60+ languages without stopping. The toolbar shows a brief "switching..." indicator for a moment and translation resumes in the new language.

Turn on live subtitles

Save translated audio

Click the rec button to record the translated voice (it turns red while recording). When you stop the session, a dialog offers the audio as an open Opus file with matching .srt subtitles (approximately 10 MB per hour). Every session is also preserved in your local session history, so dismissing the prompt does not delete the record.

Revisit your sessions

Click View saved sessions in the main window (or open Settings → Sessions) to browse past sessions stored on your device. Search by title or transcript text, click any card to read the full timestamped transcript, and click Generate summary for a recap of key points.

Each session card provides quick actions: download audio, export .srt subtitles or .txt transcripts, delete a session, or open it in a dedicated window. The header displays local storage usage and allows you to configure history retention limits.

Privacy: WireLang™ Live captures output audio locally using native system APIs (WASAPI loopback on Windows and ScreenCaptureKit on macOS). Audio is processed live for translation and is never stored on our servers. Session history (transcripts and optional audio) stays on your local device, and can be disabled or deleted at any time in Settings → Sessions.
