Let us know whether you’re asking about the Mac-local loop, the iPhone companion, research, or an existing in-person appointment. Please leave out medical information and EEG recordings from your initial message.

About early access.

The app is currently in development, and a public App Store or TestFlight link is not available yet. Emailing about early access starts a conversation; it does not guarantee a release date, a place in a study, or access to a working live headset loop.

Trying the website demo.

The home page includes an illustrated system loop (headset, compact Mac, simulated screen, phone companion) with Explore, pause, replay, and stage buttons. That picture is visual. Hear ducks and mutes in the listening demo on the same page; the system scene does not play a second soundtrack or add tones.

Use a recent browser with JavaScript enabled. Choose Music or Video, press play, then choose “Demonstrate ducks & mutes.” A duck lowers the music; a mute briefly silences it. Both vary in length and use smooth fades. Music playback keeps its place and the video keeps moving. The wave and close-up show the same volume envelope. Choose “Stop ducks & mutes” to return to continuous audio. If you hear nothing, check the page’s volume control and your device’s sound settings. You can read the explanation without playing audio.

Each example runs for 20 seconds and stops if you leave the page. Switching examples stops the current playback. These examples use no microphone or EEG device and are not training sessions.

Volume changes, with room between them.

This example changes only the volume of the original soundtrack. Some moments duck the music to 15–40% of its current level; others reach silence. Each complete change lasts 40–320 milliseconds, including smooth fades, with uninterrupted music between moments. The close-up and scrolling wave use the same timing plan as the audio.

Some interruptions may stand out, while others may be hard to notice or blend into the sound’s texture. The display counts completed ducks and mutes. It does not measure which ones you consciously noticed or what your auditory cortex processed. These values illustrate timing and are not a specification of the developing app’s EEG algorithm.

The goal is to investigate feedback outside conscious effort. Establishing unconscious detection or learning would require separate experiments. Audio and visual output timing can also vary between devices. With reduced motion enabled, the wave shows a still overview of the timing plan.

Research context: gap detection and sound properties, attention and responses to gaps, and sensitivity to rapid amplitude changes.

Music & video credits.

Both media examples use “Reverie” by Scott Buckley, released under CC BY 4.0. We excerpted 00:30–00:50, added fades, normalized the level, and encoded it for the web. The demo applies optional, timed volume ducks and mutes without mixing in any extra audio.

The video and its preview image use an excerpt of Earthrise from NASA’s Scientific Visualization Studio, visualized by Ernie Wright (USRA). It shows Earth rising above the Moon’s horizon. This is a NASA visualization. We excerpted 00:50–01:10 from the silent animation, added fades and the “Reverie” soundtrack, and encoded it for the web. NASA publishes the visualization under its public-domain reuse policy.

There is no spoken content in either example. View the complete asset credits.

Looking for in-person neurofeedback?

If you visited the earlier Noticing Mind website about a NeurOptimal session, contact James at the same email address for current appointment information. This new listening system is a separate, independent project.

You can also visit the existing session booking page. Availability and booking details are shown by the scheduling service.

Product and research questions.

See the current app status or read the research context. We welcome questions about the intended experience and the evidence still needed.
