Beyond Perception · The Missing Note

The first six harmonics of a 200 Hz tone play together; then the fundamental, 200 Hz itself, is withdrawn, followed by the 2nd and 3rd harmonics. There is no 200 Hz in the spectrum, yet most ears still hear the pitch at 200 Hz: the ear derives pitch from the common spacing of the harmonics. In the middle there is a comparison with a pure 200 Hz sine. A listening practice with no claim of any effect.

  • Reverb: room, 12% mix

In the room you can listen to each layer on its own, change its settings and save it as your own recipe.

Sound is generated on this device in real time; no files are downloaded from a server. There is a 10 s fade-in at the start and a 0 min fade-out at the end.

Compare with another sound

Hear both at the same loudness; drag the slider to the middle and they blend.

These two sounds can't share one recipe (different tuning or effects): listen to the samples one after the other.

S · Soundscape, no claim

No health or mental-effect claim at all; it is simply a soundscape.

This session isn't linked to any claim of effect.

A session's level is the weakest of its linked claims; it is never raised by a strong but unrelated claim.
