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 — MP3 recommended, this is what plays in the preview player

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).

⚠️ That's a WAV file. It'll play directly in the Marketplace/PlayTrace preview player as-is -- WAV files are much larger than MP3 and can be slow or unreliable to stream. Use an MP3 here for the preview, and add the WAV in the field below instead (it becomes a lossless download after purchase, never the live player).

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.

Already pinned it? Verify the CID

Paste the folder CID you actually pinned to IPFS and check that it resolves correctly -- catches a metadata.json that didn't upload, a filename that doesn't match what's really in the folder, or a CID that just hasn't propagated yet, before you paste it into Marketplace/PlayTrace/Radio and find out it doesn't auto-fill.
