The AAC audio is decoded and re-encoded into an Ogg file with the Opus codec. Opus is exceptionally efficient, so even though this lossy-to-lossy step costs a little quality, the output holds up well at a fraction of typical sizes.
Game engines that consume Ogg assets, web audio work standardized on Opus, Discord soundboards, and Linux-centric workflows are the usual destinations for Apple-originated M4A files. This converter moves recordings and exports across that ecosystem line in one step.
For everyday playback on phones there is no reason to leave M4A; convert only when the target toolchain wants Ogg.
Opus, the current standard for Ogg audio and the better codec at any bitrate.
A small amount, as in any transcode between lossy codecs. The high target bitrate makes it inaudible in normal use.
