MP3 to OGG for Music Production

Keep OGG out of the session itself. Lossy files inside a project mean the DAW decodes on import and re-encodes on export, and any processing you apply — EQ, compression, limiting — amplifies the codec's artifacts rather than hiding them. OGG is a delivery format: reference mixes, client sends, demos on a phone.

One trap catches people out: lossy encoding can push peaks slightly above the source, so a mix sitting exactly at 0 dBFS can clip once it becomes a OGG. Leave about -1 dBTP of headroom on the bounce you encode from — standard practice for masters, and it applies to reference files too.

Never send a lossy file to a distributor or streaming platform. They transcode whatever you upload into their own formats, so handing them an already-compressed file stacks a second lossy generation onto what your listeners actually hear. Deliver lossless; convert to lossy for humans.

Expect a similar file size; the reason to convert is playback and workflow, not disk. MP3 already discarded data; OGG will discard a little more. Pick 192–320 kbps and it won't be audible in normal listening.

The MP3 on your drive almost certainly started life in downloads, and MP3 is lossy and built for playback, so editing, production, and some apps and engines want a different format. OGG is the destination because it plays essentially everywhere — game assets and every ordinary phone, browser, and player. You won't save meaningful space — the two formats are within touching distance at 1.4–1.2 MB per minute. Both MP3 and OGG are lossy, so this pair stacks a second encode — at a generous bitrate it stays inaudible, but if a lossless original of the MP3 exists, encode the OGG from that instead.
