Press play and watch the field answer the bass.
Why it feels different
Most players show a progress bar. Sur shows the sound.
Everything you need to listen well, and nothing you have to set up first.
See the sound
The field lifts with the bass, bends with the melody and shimmers on the highs, reading the music as it plays.
Your files stay yours
Drop in MP3, FLAC or M4A files and they play right in the tab. Nothing is uploaded, ever.
Personal without an account
Likes, playlists and history save to this browser. No email, no password, no sign up.
Hands on the keyboard
Space plays and pauses, J and K move through the queue, and slash jumps straight to search.
Keeps going in the background
Media keys, headphone buttons and the lock screen control playback while you work in other tabs.

Questions
Good to know before you press play
Is Sur free to use?
Yes. Every song in the library streams for free, there is nothing to buy and there are no ads.
Do I need an account?
No. Your likes, playlists and listening history are tied to this browser with a single cookie, so there is nothing to sign up for.
What happens to files I play from my device?
They stay on your device. Sur reads them inside the browser tab and never uploads them. The list clears when you close or reload the tab.
Which file types can I play?
MP3, M4A, AAC, FLAC, WAV and OGG work in most current browsers. Titles, artists and artwork are read from MP3 and FLAC tags, and other files use their file name.
Where do the songs in the library come from?
Each one is in the public domain or shared by its artist under a Creative Commons license. The credits page names every performer, composer, license and source.
Why does the field move differently on iPhone?
On iPhone and iPad, Sur keeps music playing when the screen locks, so the field follows a gentle built in rhythm instead of the song itself. On computers and Android phones it reacts to the music directly.
Will the 3D field slow down my device?
The field pauses whenever it is out of view or the tab is hidden, uses fewer points on small screens, and stays still if your system asks for reduced motion.
Which keyboard shortcuts are there?
Space plays or pauses, J skips to the next song, K goes back, slash jumps to search, M mutes and the question mark lists every shortcut.
How do I delete my data?
Open History in the player and choose Delete all my data. Your likes, playlists and history are removed straight away.
