Opus is what you use when efficiency is the point. It was designed decades after MP3, and it shows: at 128 kbps it reaches the transparency MP3 needs 256 or more to reach, which is why messaging apps, game engines and web projects standardised on it. Converting a WAV here produces an OGG file with Opus inside, encoded in your browser. The caveat is reach: Apple's ecosystem tolerates rather than embraces it.
Questions
Why choose Opus over MP3 or AAC?
Bits. Opus reaches transparency at roughly half the bitrate MP3 needs, so files are smaller at the same quality. For the web and for voice it is the technical winner.
Where does OGG struggle?
Apple software and hardware, car stereos, and older devices. If your listeners are on iPhones, M4A is the safer choice.
What bitrate should I use?
128 kbps is the default and is transparent for most music. Voice recordings can drop to 64 kbps and still sound clean.
Is my recording uploaded?
No. Encoding happens in your browser; only you ever hold the file.
