10-band equalizer
With presets, applied as you listen.
Your music. Your stage.
Rainy is the music server you run yourself. Every song you own, on every screen you have.
1:16
No subscription. No cloud. Just your music, on your machine.
Your whole library. Beautifully kept.
Library, mixes, history and playlists. Fast, quiet, and all yours.
-
Library. Covers, tags and lengths, read straight from your files.
Mixes that know what comes next.
Rainy turns what you play, like and skip into a shelf of mixes, rebuilt every time you open it. All of it is worked out on your server.
- Supermix & My MixYour taste, split into the different things you listen to. One mix for each.
- DiscoverSongs from your own library that you’ve never played, close to what you love.
- Replay & RediscoverYour current favourites, and the ones you haven’t heard in a while.
- Artist mixesYour top artists, with the artists that sound like them.
- MoodsEnergize, Chill, Focus, Workout, Party and Sleep, picked by how songs sound, not by their tags.
Then it puts them in order.
A traditional shuffle plays songs at random, so a quiet track can land right after a loud one. Rainy shuffle plays each song next to the one it sounds most like, so a mix moves instead of jumping around. Here are the same fourteen songs both ways.
next = random(remaining)
- remaining
- the songs that haven’t played yet
- random
- every one has the same chance, however it sounds next to the current song
next = arg maxs ∈ remaining sim(now, s)
sim(a, b) = a · b‖a‖ ‖b‖
- now
- the song playing
- a, b
- two songs’ sound fingerprints: 23 numbers for timbre, tempo, rhythm, energy, loudness, brightness and key
- a · b
- how much the two fingerprints agree, number by number
- ‖a‖ ‖b‖
- divides out their size, so the score runs from 1 (same sound) to −1 (opposite)
- arg max
- pick the remaining song with the highest score
Each square compares two songs: the brighter, the more alike. The covers on the diagonal are the songs in play order, so the squares touching it are the transitions you actually hear.
| Traditional | Rainy | |
|---|---|---|
| Average match between songs that play back to back | — | — |
| Roughest jump the least alike pair in a row | — | — |
Match is sim as a percentage: −1 is 0%, 1 is 100%.
Every song gets its own show.
Open the fullscreen player and hit the lights. The song’s key and genre pick the colours.
Pick how hard the rig goes.
Auto follows each song’s energy, Chill keeps it slow, Hype turns every chorus into a drop.
It hears the drop coming.
- ListenAfter import, the server analyses each song: beats, downbeats, and kick, snare and hat hits.
- StructureSections get labels: intro, verse, build, drop, breakdown, outro. The song’s key picks the palette.
- ForesightRisers, drops and silences are marked ahead of time, so the rig blacks out a beat before the drop instead of reacting after it.
- SpeedAnalysis runs on every CPU core, or on an NVIDIA GPU when there is one.
