Seed #9214 is one entry in the Calming Melodies 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 single felt-piano voice: detuned string oscillators, a hammer thud on the attack, and a filter envelope that darkens the tail so notes decay like felt rather than steel.
The musical material uses Japanese Hirajoshi at 62 BPM, tuned to 741 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 in the background while working or reading, at a volume where you stop noticing it after a few minutes. This seed leans toward cozy reading and runs at 62 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.
