When listening to RAS-1 one hears the waves of Lake Michigan. A sample of the sound may be heard here.   Embedded within the recording is a carefully constructed set of rhythmic sounds. For optimal effectiveness the structure of the rhythms should not be altered. Therefore a few helpful guidelines are suggested.

         First of all the CD must be listened to with stereo headphones. Some people enjoy the sound of the waves so much that they play the CD as ambient background throughout their day. There is nothing wrong with this but neurological coupling will only occur when heard via stereo headphones.

         The embedded rhythms are very carefully constructed. Minor alterations reduce or negate their effectiveness. All graphic equalizers, loudness enhancements, bass boosts, 3-D effects, surround sounds, audio dynamic processing or any other method that modifies or alters the structure of the sound must be disabled. These types of audio enhancements are so prevalent in today's systems that one may not be able to find the methods for controlling them. There are even some units that have permanent audio modification and they cannot be disabled.

         However altering the amplitude, frequency, rhythm, modulation or the nature of the masking sound by as little as 5% can significantly reduce the effectiveness of RAS-1. Therefore converting the CD to a mp3 file can be challenging. There are many methods used to compress audio in the mp3 conversion process. Some of these will drastically reduce or destroy the effectiveness of RAS-1. If you want to have the audio as an mp3 file please contact the author for assistance.

         This is the first in a series of 24 CDs. After a certain period of time the neurological response may be reduced or a person may decide that they are ready to try the next CD in the series. How long that is, or whether it occurs differs from person to person. The progression from one CD to the next is incremental and very gentle. It is suggested that one fully explore the current neurological response to a given CD before progressing to the next. Please feel free to contact the author if you have any questions.
