- Mixtape makers and developers building cassette players
- Worth noticing
- A tape side is one continuous recording; track markers label songs without splitting the side into separate tracks.
Field notes
The format treats cassette details as part of the file, including its label, J-card, record tabs, and history. The browser deck demonstrates winding and flipping sides rather than seeking between tracks, while the linked validator is listed for Python 3 and the standard library. The page describes the specification as a release candidate, not a finalized standard.
