What is Opus, and how do you transcribe it?
Opus (Opus) is an audio format you'll typically find from WhatsApp, Telegram, and Discord voice notes and VoIP. A modern low-latency codec specifically optimized for speech — very common for voice messages.
To turn it into text you don't need to convert anything first — upload the Opus file (or paste a link) and Whipscribe returns a clean transcript with speaker labels and per-word timestamps, exportable to TXT, SRT, VTT, or DOCX. Everything runs on private infrastructure that never hands your file to a third-party AI service.
