Seed #3520 is one entry in the Nature & Fire pillar of Calm Sound Archive. It is generated in the browser with the Web Audio API, so nothing is streamed and nothing is downloaded: the same seed number always produces the same piece of audio.
What you are hearing
Brown noise for the body of the fire, plus randomised bandpass bursts for pops and embers, with a rain layer behind it.
The musical material uses Balinese Pelog at 65 BPM, tuned to 639 Hz. A binaural offset of 4.3 Hz separates the left and right channels slightly, which is what gives the track its width on headphones.
When to use it
Use it as background for reading, cooking, or falling asleep. The layers are steady enough to ignore. This seed leans toward deep sleep and runs at 65 BPM, so it moves slowly enough to sit under conversation or sleep.

How to listen
- Press play and choose a session length between five minutes and eight hours.
- Headphones give the binaural layer room to work; speakers still play the track but flatten the stereo image.
- Keep the volume where you can still hear the room. The fade-out at the end of a session is ten seconds, not a hard stop.
