FAQ

Frequently asked questions

What makes Opus special?

Opus is one of the most efficient audio formats around and delivers better quality than MP3 or AAC at low bitrates. It's excellent for speech and streaming.

Is quality lost during conversion?

Yes, Opus is lossy, so some of the WAV's detail is removed. Thanks to its high efficiency, the audible loss stays very small.

Where can I play Opus?

Modern browsers, many messengers and current players support Opus. On older devices, however, compatibility can be limited.

Are my recordings uploaded?

No, conversion happens locally in your browser by default. An optional server mode is available for very large files.
