AudioBatch delivery guide
How to preserve audio metadata during conversion
Metadata support varies by container and codec. A dependable workflow distinguishes embedded tags from sidecar records and verifies what actually reached each output file.
Inventory the source tags
Read title, artist, album, year, track, genre, comment and artwork before conversion. Empty values should remain intentional rather than being replaced by guessed data.
Map tags to the target container
Write ID3 metadata for MP3 and common media metadata for M4A. WAV and FLAC delivery policies may also use explicit sidecars for a human-readable record.
Keep artwork separate when useful
Embed artwork where supported and copy the original image beside the batch when the client or archive benefits from a standalone asset.
Verify after writing
Inspect the completed outputs and include the exact tags, filenames and checksums in the final report. Do not assume an encoder preserved metadata just because it completed successfully.
