Convert OGG to M4A
Drop an .ogg file and download an .m4a carrying AAC audio at 192 kbps. Sample rate and channel count are preserved.
This is the conversion for moving open-format audio into the Apple and mobile world, where .m4a is what libraries, sync tools, and app bundles expect.
What the second encode costs
The Ogg stream decodes to PCM, then AAC encodes it. Both codecs are lossy, so the M4A inherits the Ogg’s limits and adds a small amount of its own. 192 kbps AAC is generous enough that the added loss rarely registers.
Where an original WAV or FLAC exists, encode from that instead and skip the intermediate generation.
Metadata
The MP4 container can hold title, artist, and album tags, which is one practical advantage over a bare Ogg from a game asset folder. Tags are not carried across by this conversion, so add them in your library manager afterwards.
