Binaural Beats Alpha to Delta and Back mp3

This is a raw binaural beat meditation track someone asked me to create.

It creates *** the same *** binaural beat patterns at three different frequencies : 132, 264 and 528 (sine waves, of course). These are played as such on the right.

The binaural beat input is then created by adding a shifted frequency on the left where the binaural beat frequency is subtracted from the frequency on the right.

So the brain will create the same "beat" three times simultaneously.

0 - 10 min : 9 Hz difference (so freq bands of 123, 255 and 519) (Focus on goals / content.)
10 - 30 min : linear drop from 9Hz to 3Hz over 20 min. (Frequencies on the left gradually get higher. In terms of brain waves, we move from alpha over theta to delta, "connect content through dreamstate to subconscious" )
30 - 40 min : continuously 3 Hz (Delta) (Powernap!)
40 - 60 min : linear rise from 3 Hz to 9 Hz (Time to go back...)
60 - 70 min : continuous 9 Hz again (Regain sanity.)

I have created an mp3, at these frequencies things should work fine. Wav is available on demand.
