Benefits
A practical format guide for browser audio workflows, editing copies, and lighter delivery files.
The guide frames each format around editing, delivery, and speech-heavy workflows instead of vague audiophile claims.
WAV is treated as the stable local output, while AAC and Opus exports stay tied to browser support.
Once the format decision is clearer, you can move into the related Picmu page without rebuilding the workflow.
Tradeoffs
It is the safer output for editing copies, but rarely the lightest delivery format.
MP3, M4A, and Opus can all be practical, but the best one depends on compatibility, browser support, and the destination stack.
Bitrate, channel mode, sample rate, and the browser's export path still matter after you pick the container.
