Opus
Opus Audio Codec
Opus is the best general-purpose lossy codec available — it beats MP3 and AAC at every bitrate and handles both speech and music. WhatsApp voice notes, Discord and YouTube all use it, and almost no non-browser software opens it.

Opening a .opus file
If you landed here because something handed you a .opus file and
nothing on your machine will open it, converting it to a format you already have a
reader for is usually faster than installing new software. Every conversion above runs
in this browser — the file is not uploaded, so it works on a locked-down work machine
and on a file you are not allowed to send anywhere.
