Faseschijf. An instrument, not a playlist.

Most relaxation audio is static. You press play, and the same track runs from start to finish, whether you're starting the session tense or already halfway toward calm. The Faseschijf works differently. It reads two things before it starts composing: what time it is and how you feel in that moment. From there it generates a session that actually moves toward that, instead of just playing something back.

Read below the disc what the different parts do and how it works.

How it works

The disc itself is a clock. It divides the day into four phases: Wake, Focus, Unwind, and Sleep, and automatically picks the phase that matches the current time. Each phase has its own target frequency and its own scale.

At the start, you indicate how wound up you feel, from calm to tense. That sets the starting point of the session: richer and faster if you're tense, sparser if you're already calm. From there, the session glides gradually toward the target state of the chosen phase, over the full duration you set.

The components

Circadian phase. Automatically linked to the clock, or manually overridden if, say, you want a sleep session during the day.

How wound up do you feel right now. Your input sets how the session starts. The higher it is, the richer and faster the start, after which everything slows toward the target state.

Session length. 10, 20, or 30 minutes. Sets how much time the transition to the target state is spread over.

Engine. The binaural layer and the generative tones together, built entirely by the computer, different every time. Adjustable with its own volume control.

Your music. You can add your own file, a droning track, a chant, whatever you choose. Plays automatically, with a soft crossfade at the seam so you never hear a click or jump. It has its own volume control, fully separate from the engine, so you can tune both independently.

Texture layer. Sparse, random tones on top of the rest, never a fixed repeat. Toggle on or off as you like.

Practical notes

It works best with stereo headphones; binaural separation requires two separate ears, not speakers. This is an instrument for relaxation and focus, not a medical device and not a substitute for treatment.
