Traditional / experimental practice

Beyond Perception · Perception Lab

Five phenomena from the previous parts, each about a minute and a half, in turn and without guidance: the missing note, the endless staircase, the slow pulse, the vanishing tone and the harmonic that breaks away from the blend. Try to name what you are hearing yourself. The panel beside it has a short blind test. 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.
