Seed #7052 is one entry in the Sleep & Lullabies 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
A sub-bass pad with a very low cutoff, designed to sit under everything else rather than call attention.
The musical material uses Balinese Pelog at 52 BPM, tuned to 432 Hz. A binaural offset of 6.1 Hz separates the left and right channels slightly, which is what gives the track its width on headphones.
When to use it
Use it at low volume as you fall asleep. The eight-hour timer exists for exactly this. This seed leans toward deep sleep and runs at 52 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.
