Metadata Generator — web3audio

Fill this out once, pin it alongside your audio (and optionally artwork) in one IPFS folder, and that single CID auto-fills the Marketplace, PlayTrace, and Radio's submission forms -- each one just reads the fields it recognizes and ignores the rest.

Song / track title

Artist name (optional — used by Radio; Marketplace collects this separately in its own upload form, not from here)

Description (optional — used by Marketplace/PlayTrace)

Category (Marketplace)

Genre tag (optional — used by Radio; any free-text genre)

Audio file

If you plan to submit this to SignalChain Radio too, it must be MP3 -- Radio only accepts MP3 (it's streamed to every listener on every play, so format matters more there than a one-time download). Marketplace/PlayTrace accept any audio format.

Artwork file (optional — used by Marketplace/PlayTrace; Radio doesn't use artwork)

WAV file (optional — Marketplace-only, lets buyers download lossless)

Minting as an NFT too? NFT metadata needs a different shape (fully-resolved URLs instead of folder-relative filenames), so it's not something this file can double as directly. Pin this file with your audio/artwork as usual, then on Mint's page paste this folder's CID into its own "Generate NFT Metadata" step -- it already exists specifically to convert a metadata.json like this one into the NFT-ready version.
