[Summary: The second (2nd) binaural experiment. As with all of these, the base tones are altered in some way to induce an effect that is left unstated to avoid an expectation bias.]
This is designed to be a standalone binaural, though it may work well with spirals or other imagery.
As with the prior experiment, the sound will change at several points throughout the file to create a more powerful effect.
You may notice a heavy pulsing sensation, followed later by a spiraling sensation. Do let me know how those feel.
As always, enjoy.
