2##    Please note: These tone-sets are based on data from a document
3##    that appeared on USENET, from someone who appears to have
4##    measured the frequencies used on some of the Monroe Institute
5##    tapes.  See "focus.txt" for more details.  Although the
6##    frequencies were measured, the relative amplitudes of the tones
7##    were not, so the results are not likely to be exactly the same
8##    as the Monroe Institute tapes.  Also I believe that the Monroe
9##    Institute uses a guiding voice that leads the subject through
10##    the experience.  Despite that, these tone-sets (or Focus levels)
11##    may be useful for experimenters to base their own tone-sets on.
