Seed #9981 is one entry in the Space & Ambient 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
Layered triangle oscillators with slight detune, filtered low and left to drift without rhythm.
The musical material uses F Lydian at 74 BPM, tuned to 852 Hz. A binaural offset of 4.4 Hz separates the left and right channels slightly, which is what gives the track its width on headphones.
When to use it
Use it for long, quiet blocks where you want texture without melody drawing attention. This seed leans toward study & focus and runs at 74 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.
