Metadata & Tag Write-back

Icoustic treats files as the source of truth.

Editing

You can edit a single track or apply album-level changes. The UI updates immediately; tag write-back happens through TagLib for ID3 (MP3), Vorbis comments (FLAC), and MP4 atoms (M4A).

Why this matters

Edits aren’t trapped in a proprietary database. If you open the same files in another player later, your ratings and corrected tags go with them.

Rescans

Icoustic recognizes its own writes so rescans stay clean — you won’t get phantom “changed” tracks every time you rate a song.
