- The site distinguishes composed music, generated tone layers, and post-export checks rather than treating a frequency label as proof.
Field notes
The page separates the composed bed, generated tone layer, and verification step, describing each as a different kind of claim. Its evidence section gives qualified summaries rather than presenting all frequency research as settled: for example, it distinguishes self-reported sleep quality from measured sleep and notes inconsistent results across binaural-beat studies. The site says new tracks will be added as they are finished.
