Beat Builder — a free online beat maker built from real, cleared sounds
Hit spin, and a real drum, bass, keys, or vocal loop from Selekt's cleared catalog drops into your workspace — a free online beat maker built for producers and composers, not algorithms. Every sound is royalty-free and screened for copyright before it ever reaches you, so you know exactly what's going into your beat. Don't like what landed? Spin again for something else entirely. And where most sample libraries hand every producer the exact same downloadable pack, Beat Builder pulls a different random sound into every lane — so the beat you walk away with from your session is one that only you have.
- Spin a lane. Pick a role below — a cleared sound drops in instantly.
- Lock what works, then spin the rest until the groove clicks.
- Shape each sound in 🎛 Tools — filter, space, pitch, stutter.
- Export your loop — full mix, per-lane stems, and the clearance receipt.
Start with a lane.
Pick a role below — we'll pull a cleared loop into it instantly. Lock what you like, spin the rest, cut the pieces you love, and shape a loop nobody else has.
What do you want to start with?
Every sound here is a cleared CC0/public-domain loop from the Selekt catalog. Want your own sounds in a lane? The complete stem separator turns a track into per-instrument stems — upload support lands here next. Your session autosaves in this browser.
How it works
- Spin a lane. Pick a role — Drums, Bass, Melody, Chords, Vocal, Texture, Nature & Animals, Brass Winds & Horns, Cinematic / World, or Sound Effect — and a real cleared sound drops in at random.
- Shape what landed. Every clip has its own tools: trim the region, nudge the pitch, change the speed, add reverb or echo, or stutter it with Repeat. Don’t like it? Spin again for something else.
- Rearrange and combine. Cut a piece into its own lane, place copies anywhere on the grid, and lock the lanes you love so they hold still while you keep spinning the rest.
- Export the folder. Download the mixed loop, every lane’s individual stem, and a certificate of clearance naming what you built it from — all in one folder.
Build a beat online, and yours is the only one that exists
Beat Builder doesn't generate anything, and it doesn't hand you a file everyone else already has either. Every drum hit, bassline, chord, and vocal phrase is a real recording from Selekt's catalog — screened, cleared, and pulled into your session at random. Spin a lane for a different sound every time; keep what you like, lock it, or spin again. Shape what lands: trim it, nudge the pitch, add reverb or echo, cut a piece into its own lane. Most sample libraries hand every producer who downloads the same pack the identical files — make a beat here instead, and the combination is built live, in your browser, from whatever landed for you. Download it, and you're not picking a preset — you made it, and you're the only one who has it.
Frequently asked questions
Is Beat Builder really free?
Yes — spinning, shaping, cutting, and rearranging lanes all run free in your browser, no account needed. Exporting the finished loop uses a download like the rest of Selekt.
Where do the sounds come from?
Every sound is a real recording pulled from Selekt's cleared catalog — screened before release, never generated. Nothing here is AI audio; each export includes a certificate of clearance naming what you used.
Can I land on the same combination twice?
Not by spinning again — each spin pulls a different random sound from the catalog. Lock a lane you like and it holds still while you keep spinning the rest, so the exact combination you finish with is one you built, not one anyone else picked.
Can I use my own audio instead of spinning?
Yes — the “Your sound” tile uploads a file straight into any lane, and a Stem Separator ZIP fans out into one lane per stem automatically. Your own audio is never certified as cleared — only catalog sounds are; the certificate says so plainly.
How is this different from other beat makers?
Most beat makers either generate audio or hand every producer who downloads the same pack the identical files. Beat Builder does neither — it’s assembled live, in your session, from real cleared recordings chosen at random, so the beat you land on only exists because you built it.
Want just one groove instead of a full arrangement? Drum Kit spins a single cleared beat you can re-skin with any kit. Already have a track's stems? Stem Lab re-voices them onto real cleared instruments. Or browse the catalog directly at Loops.
