Seed #0242 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 F Lydian at 67 BPM, tuned to 396 Hz. A binaural offset of 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 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 67 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.
