The music player for DJs – from your first mix to your residency

Sort your library by sound. Not by store genres.

BPM and key tell you if two tracks mix. Timbre tells you if two tracks belong together.

First the live demo without an account, then your own Library. Free. How your music gets in

Timbre listens to every track with the same ear. And estimates how much of each genre is in there: for example 62% deep house, 25% dub techno, 13% minimal. You set the rules. Timbre sorts.

Before → after in five steps

01 · Chaos

Your folder is a Where’s Waldo.

Promos, purchases, edits, “final_v3.wav”. The track you’re looking for is in there. Definitely. Somewhere.

Happens to everyone, living room or booth: searching eats the time you need for listening.

02 · Analysis

Timbre listens to every track, start to finish.

BPM and key: measured. Energy (o to +++) and genre mix: estimated, by a model. Each value says which.

One yardstick. Instead of ten stores with ten opinions.

More in the help: What does Timbre measure?The Genres tab

03 · Sound

Birds of a feather sound together.

Eight ways lead out of the playing track: Hold, three Key boosts, three Key drops, Mood Change. The mix octagon shows how many tracks wait down each one.

Key boost up top, Key drop below. The next track is there before you search.

More in the help: Mix octagon on the home page

04 · Sort

Pack your record bag – with the tracks you really need.

You make the rules, Timbre sorts your playlists: warm-up, peak time, dub corner. The energy curve shows up front where the evening is heading.

Example: 4,812 files become 38 tracks for “Warm-up for Mo”.

05 · Back

Back to Rekordbox. Tidied up.

One export, and your playlists sit in Rekordbox. Cues, ratings and colors stay. Timbre’s beatgrid only comes along if you want it.

On its own, Timbre doesn’t touch your files. Your setup stays your setup.

And the records on your shelf?

They get their turn too: scan records, shelve them, print labels for the sleeves.

Your records get the same values as your files. If Timbre already knows the tracks, the barcode is enough. If not, you play them for a few seconds.

Coming soon Built, but not switched on yet: record shelf, barcode and labels are coming soon. Listening along (play-in, Live Vinyl) only starts once its privacy review is done.

01 · Scan
Barcode on, tracklist out.
The tracklist with A1 to B2 comes from MusicBrainz. Tracks Timbre already knows get BPM, Open Key and energy right away.
02 · Play in
Unknown? Drop the needle.
10 to 20 seconds are enough. Timbre recognizes the track or measures BPM and energy live. The audio isn’t stored.
03 · Shelve
Onto the shelf, with a label.
Every record gets a slot, Timbre suggests the next empty one. Plus labels for the sleeve with BPM · Open Key · energy, on standard A4 sheets.
04 · Live Vinyl
While you play: breakdown in 0:42.
Timbre listens along, shows where the needle is in the track and suggests the next record from your shelf, with its slot.

Timbre on your devices

Timbre comes along. Everywhere.

From your desk to your pocket. Each device does one thing really well – and all of them know your library.

One track runs through it all: Aine, 124 BPM, key 8m, energy ++.Example

iPhone · SiriIn testing · for the store launch

Just say: more energy.

Siri picks the next track the way the octagon does: hold the tempo, match the key, energy up or down. Even with your phone locked.

In five languages, with headphones or from the lock screen.

iPadIn testing · for the store launch

Dig from the couch.

The octagon shows where you can go after the playing track. One tap, and Aine sits in your Tag List.

The same app as on iPhone, with room for the big player.

What Timbre stands on

Standing on the shoulders of giants.

Timbre stands on open research. We measure key with Essentia; genre mix and vocals are estimated by open models from the Music Technology Group (MTG) at Universitat Pompeu Fabra, Barcelona – years of research, shared openly. Everything you see and do in Timbre is built on top.

Listen like you play.

The music player for DJs – from your first mix to your residency.

Hear your library the way you play: with tempo, level and bands in view – in the browser, from your online storage.

Tempo like on a CDJ
±6, 10 or 16 %, fine steps of 0.02 %. Master Tempo keeps the key; without it Timbre shows the new key.
How it works
Fader, gain and meters
Fader in dB like on a mixer, auto gain to −14 or −10 LUFS, trim ±12 dB and a limiter against clipping – shown as an LED meter or two VU needles.
How it works
Bands and cover art
LOW, MID and HI as lanes like on a DJM, plus the vocals lane and the artwork from your tags.
How it works
Queue
“Play next” or add to the end, whole lists at once – afterwards the list you started from keeps playing.
How it works
Listening mode for your phone
Data saver or original, loudness matching, lock-screen buttons – and switching pages doesn’t stop the music.
How it works

On the iPhone the server matches loudness; there’s no fader or limiter there – your device buttons apply.

Your library goes where you go.

Huge library, but never with you – or only on your laptop?

timbrecloud: your music everywhere – listen, dig, pack your record bag, in the browser and on your phone.

Beta timbrecloud is in beta: enabled on request, with a fixed quota per account.

Your music can just as well stay in your own online storage – timbrecloud is an option, not a must.

Your music stays yours.

On its own, Timbre only reads from your online storage. What’s stored from it: measurements, fingerprints and names – no music. No trackers, no ads. Every value shows its source.

Questions everyone asks.

Do I have to upload my music?

No. You connect your online storage; on its own, Timbre only reads. What the catalog already knows is in right away; unknown files are read briefly, measured and deleted.

Does Timbre change anything in my Rekordbox?

No. Timbre only reads your collection in your browser and writes nothing back. Whether you take the playlist from Timbre into Rekordbox is up to you. Timbre doesn’t touch your cues, touches your beatgrid only if you turn on “Include beatgrid” when you export, and writes into your music files only when you start that yourself.

How accurate is it?

Every value shows its source. BPM, key and frequency bands are measured – your tags sit right next to them so you can compare. Genre mix, energy and vocals are estimated by a model: a solid guide, not a measurement. Where Timbre and your tags disagree, you see both.

What does it cost?

Nothing. Donations for servers and measuring runs are welcome.

What happens to my data?

No trackers, no ads, only technically necessary cookies. You can export your data and delete your account at any time; protect it with a passkey or a code from your app.
