About Free BGM
A free music library for people who make videos and podcasts, and for anyone who wants calm sound while they work or sleep. Made and maintained by Casper.
What this is
Free BGM is a free music library on casper.tw. Pick music by what you're making, like a podcast or a game, or by mood, and download full tracks as MP3 files at 192 kbps.
If you'd rather just listen, the focus, sleep and lofi stations shuffle their tracks for hours, and the noise players make white, pink and brown noise in your browser with no files to download. A sleep timer fades the sound out on its own.
How the music is made
The tracks are made with Google's music generation model. We write a short brief for each use and mood. After the model makes a track, we even out the loudness to -18 LUFS, add the track name, ID and web address, and save it as a 192 kbps MP3.
The briefs don't use the names of real artists, and we don't present the music as written or performed by real people.
Each track has a permanent ID, like bgm-000123, so you can link to it and find it again.
How we write the research boxes
The “What research says” boxes on the station and noise pages only cite studies published in journals. They explain in plain words what each study looked at, what it found and where it falls short, and show the date we checked the sources.
They're there to show where the research stands, not to give medical advice. If trouble with sleep or attention keeps going, talk to a doctor.
Who runs it

Questions about this site
- How can this be free?
- The site is supported by ads, so the music, stations and noise players are free to use, and downloads don't need an account.
- Can I submit my own music?
- Not at the moment. Every track here is one we made ourselves.
- Can tracks be removed?
- It can happen, for example after a well-founded infringement notice. Tracks you've already downloaded can still be used under the terms from when you downloaded them, and a removed track's ID is never reused for another track.
