Seed #9279 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 C Major Pentatonic at 48 BPM, tuned to 741 Hz. A binaural offset of 6.2 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 stress relief and runs at 48 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.
How this seed differs
Seeds in the Space & Ambient pillar share an engine family, but the parameters are not interchangeable. Here the filter ceiling sits at 837 Hz and the binaural offset at 6.2 Hz. For comparison, seed #9278 cuts at 605 Hz, this one at 837 Hz; seed #9280 runs at 67 BPM, faster than the 48 BPM here.
The tuning is 741 Hz, which shifts the whole scale away from the more common 432 Hz reference. At 48 BPM the phrase repeats roughly every 5 seconds, so the loop is long enough that it does not feel like a short sample on repeat.
When this one works best
Long blocks of deep work or reading. With no transients, it stays out of the way for hours.
The mood tag for this seed is Stress Relief. Treat it as a starting point rather than a rule: the same track can sit under a work session at low volume and under sleep at an even lower one.
Questions about #9279
Does this seed download any audio?
No. The track is synthesised in the browser when you press play. Nothing is streamed, and there is no MP3 file behind it, which is why the same seed number always sounds the same on any device.
Can I leave it running for eight hours?
Yes. The timer goes up to eight hours and fades out over the last ten seconds instead of cutting abruptly. If you only need a short reset, the five-minute default is already selected.
Why does it sound different from the neighbouring seeds?
Because the engine reads the seed number to set the filter, the tuning, the tempo and the stereo offset. Small changes in those values change the texture more than a change of instrument would.
