Your best 100.
Sent in seconds.
Not a drive, not a dump — Catalog holds your best 100 sounds, ready to play, tag, and send with a link that tracks the moment it's opened.
Waveform player · Auto-expiring links · Tracked opens
Your best 100, ready to send.
Catalog isn't built to hold everything you've ever made — it's built to hold the 100 sounds you actually reach for, tagged and one link away from anyone.
Your best 100,
not your whole drive
100 isn't a limit we ran into — it's the point. Just the sounds worth sending, nothing to dig through.
Listen and organize
instantly
BPM, key, type, and tags — right on the shelf.
Share a link.
Watch it get opened.
Every link expires after 14 days — no stale links floating around.
This isn't storage.
It's your best stuff, ready to send.
Catalog was never built to store hundreds of files quietly in the background — just the ones you'd actually want a buyer to hear, one click from being sent.

TrackedEvery sound that makes the shelf is tagged, playable, and one click from being sent — nothing else clutters the view.
Stop scattering your best sounds everywhere.
A Dropbox folder here, a WeTransfer link that quietly expired there, a text asking if they even got the beats — none of it tracked, none of it organized. Catalog is one library with a link that tells you the moment it's opened.

Everything Catalog does
Upload your best 100
MP3s up to 5MB each — a hard cap by design, so Catalog stays your best 100 sounds, not your whole drive.
Built-in waveform player
Every sound plays right on the shelf — no download, no separate app, just click and listen.
Favorites & tags
BPM, key, sound type, and two tags per sound — star the ones you reach for most and find anything in seconds.
Share links that expire
Pick your sounds, generate a link, and it stops working in 14 days automatically — no stale links floating around.
A public page that plays
Recipients get a clean page with a spinning-vinyl backdrop — play, download one sound, or grab the whole pack as a zip.
Know when it's opened
Every send is tracked — Opened, Not opened yet, or Expired — so you're never guessing if they've heard it.
Stop hunting for files. Start one library.
Catalog is not an add-on, no separate bill, already in your Arvo plan.
