Supported formats

musefs synthesizes fresh metadata for each supported container while serving the original audio bytes verbatim. Each format has its own page for the exact synthesis behavior and lossy edges.

Format	Extensions	What is synthesized
FLAC	`.flac`	Regenerates the metadata blocks; preserves `STREAMINFO`/`SEEKTABLE` bit-exact
MP3	`.mp3`	Regenerates the ID3v2.4 tag; audio frames (incl. Xing/LAME) untouched
M4A	`.m4a`, `.m4b`	Rebuilds the `moov` atom, patching chunk offsets; `mdat` served verbatim
Ogg	`.ogg`, `.oga`, `.opus`	Regenerates header pages; audio pages verbatim, only page seq/CRC patched in place
WAV	`.wav`	Regenerates the RIFF front (`LIST`/`INFO` + embedded ID3v2); `data` payload verbatim
