The sample library that listens.

Forty thousand files, no idea what is in any of them. CRATES analyses every one — tempo, key, loudness, instruments — then lets you search them the way you'd describe them.

What it does

It listens to the file, not the filename.

Vocal_Loop_FINAL_2.wav tells you nothing. CRATES opens it, measures it, and writes down what it heard.

Tempo, key, loudness

Measured to the decimal, not guessed from a filename. This is the half that has to be right, so it gets the most care.

Genre, mood, instruments

A model listens to each file and tags it, so “dark” and “piano” become things you can search for even when nothing says so.

Search by ear

Describe the sound in plain words and it finds the closest matches — or point at a sample you like and ask for more like it.

Works on your iPad

It serves your library to anything on the same wifi. The machine holding the samples doesn't have to be the one in your hands.

Nothing is uploaded

The analysis runs on your machine and the results stay there. No account, no sync, no folder of unreleased work leaving the building.

Fast on your GPU

Roughly four times quicker on an NVIDIA card, with byte-identical results. A big library is an afternoon, not a weekend.

Marketplace

Buy a beat. It's already in your library.

Every other store ends with a zip in your Downloads folder. Buy inside CRATES and it arrives analysed — searchable by tempo and key alongside everything you already own, the moment the bar finishes.

Four prices, one recording

A beat isn't sold once. MP3 lease, WAV lease, the trackout with stems, and the exclusive that takes it off the market — same audio, different rights. CRATES treats those as what they are.

Selling starts from what you already have

Pick a track CRATES has already analysed and the listing arrives filled in — tempo, key, genre. It builds the 30-second preview itself. You set the prices and publish.

Your buyers never lose it

Purchases follow the account, not the machine. New laptop, same library.

The marketplace is built and in testing. It cannot take payments yet — that needs the last piece of payment setup. Join the list below and you'll hear the day it opens, whether you want to buy or sell.
How it works

Three steps, then never again.

Point it at your folders

Wherever the samples already are. CRATES reads them and writes nothing to them unless you ask it to.

Leave it for an afternoon

It opens every file and measures it. About two seconds a track, four times quicker if you have an NVIDIA card. It only ever runs once per file.

Ask it for things

“140 dark trap, F minor, no vocals.” “Something like this, but slower.” The library you already had, finally answerable.

Pricing

Free while it's in beta.

Everything CRATES does with your own files — scanning, tempo, key, loudness, search, playback, export — works forever without paying anyone. That isn't a trial; it's the deal.

Tell me when it opens
The Pro price isn't set yet. Rather than put a number here that might change, the list below gets told first — and beta users get it cheaper than whatever it lands at.
Early access

Be there when it opens.

One email when the build is ready, and one when the marketplace opens. Nothing else, and never to anybody else.

No tracking on this page. Your address is stored so we can send those two emails, and for nothing else.
