Signal Library

The Signal Library 

Evidence-based binaural beat sessions. Full frequency disclosure. No masking. 

If binaural beats haven't worked for you before, the signal was probably buried.

Most binaural beat recordings on streaming platforms layer the tones under ambient music or nature sounds. It feels relaxing. But the research is unambiguous. Adding any background layer to a binaural beat signal eliminates the measurable entrainment effect entirely. Your brain never builds the beat.

Every session in the Chromasound Signal Library is different.

Pure carrier tones. No ambient music. No masking. No background noise. Every frequency calculated, verified and disclosed before recording. The binaural gap sits in the exact range the peer reviewed research supports. The carrier tones are derived mathematically from visible light frequencies, divided down exactly 40 octaves into the audible range.

If you can hear the tones clearly, the signal is reaching your brain.

That is the only standard that matters.

Browse By Category 

Sleep & Recovery Delta range binaural beats for deep sleep, slow wave sleep, physical restoration and full nervous system reset. 

Carrier tones in the Lower and Deep octave for the heaviest, most grounding signal possible.

Focus & Flow Theta and Beta range binaural beats for sharp concentration, creative flow, active thinking and sustained attention. 

Normal octave carriers keep the signal bright and present.

Calm & Anxiety Theta range binaural beats for nervous system regulation, vagus nerve reset, parasympathetic activation and anxiety relief. 

Lower octave carriers produce a warm settling signal without pushing toward sleep.

Grounded Meditation Lower Theta range binaural beats for deep meditation, grounded presence and conscious inward stillness. 

Deep and Lower octave carriers for a heavy, slow, embodied signal.

All sessions are pure tone recordings. Headphones required. No ambient music. No masking. Peer reviewed science cited on every product page.
