If the destination is a game engine, a web page or an app bundle, Opus in an OGG container gives the smallest files that still sound transparent, and encoding from uncompressed AIFF source is the ideal starting point. This page does that encode locally: 128 kbps by default, adjustable, with the AIFF's full quality feeding the encoder rather than an already-lossy intermediate. Sound designers get delivery files without their source audio touching a server.
Questions
Why encode Opus from AIFF rather than from MP3?
Every lossy generation stacks. Encoding from the uncompressed AIFF gives Opus clean input and the best result the bitrate allows.
Is OGG right for a podcast or music release?
Only if you control playback. For public releases where Apple listeners matter, M4A or MP3 avoid support questions.
What about looping game audio?
Opus decodes with a small amount of priming; most engines compensate automatically. Seamless loops are worth testing in-engine.
Is this really all local?
Yes. The encoder runs inside the page; your files and the results stay on your machine.
