Why is Sound Therapy now on CD. Doesn’t it have to be analogue?
In some of our books we explained that we only released Sound Therapy on cassette tape and not CD, because cassettes can have analogue sound, whereas CDs are digital. Digital sound is prone to errors and many forms of digital sound are of very low quality and have no or little therapeutic value. During the evolution of CDs in the 70s, 80s and 90s, some of the reproduction methods used were of very low quality. However, advances in technology did improve the sampling rates and the accuracy so that a good audio quality could be achieved.

More detailed information on the filtering and reproduction process is included with the Listener’s Workbook, supplied with the Basic Kit. All of our original music, mastering, filtering and activation — the whole Sound Therapy process — is still done on analogue equipment. With our method [and this is unique today] only the final playback is on
