{ I have provided a .VOC called river.voc which is in stereo at 22K and 
  still sounds nice when looped.  }

source = file river.voc
source = stereo           ; Using the stereo option works best on naturally
                          ; recorded sounds, such as oceans, rivers, etc.
                          ; The brainwave pattern is generated using the 
                          ; sounds in the environment that are the same on 
                          ; both channels.  The advantage is everything still
                          ; sounds like it is in stereo.

source = wave of 0.0625 at -10 to 10

wave from 7.8hz sep 8 to 3.8hz sep 16 in 288 seconds 14 cycles
