Seed #0624 is one entry in the Rain & Piano 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 felt-piano voice built from detuned triangle and sine oscillators, with a soft hammer transient on each attack and a lowpass filter that closes as the note decays. A filtered pink-noise layer sits underneath to suggest rain against glass.
The musical material uses Balinese Pelog at 75 BPM, tuned to 639 Hz. A binaural offset of 1.9 Hz separates the left and right channels slightly, which is what gives the track its width on headphones.
When to use it
Use it when you need a room to feel calmer without going silent. The piano gives the ear something to follow; the rain masks background noise. This seed leans toward study & focus and runs at 75 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.
