Also, if you're curious about where I particularly find some interest in sbagen, header 3.6 in this documentation file details the "drop" program. https://uazu.net/sbagen/sbagen.txt
It's a text file, so yea, no direct links sadly, but hopefully scrolling isn't too onerous.
The tl;dr of it though is these top two paragraphs:
This is a series of sequences that are designed to be used fairly
often and over a long period of time (e.g. daily over several years).
By working through all these sequences, you stimulate all the
different combinations of carrier frequency and beat frequency over a
large range (0-200Hz carrier, 0.3-10Hz beats). According to some
people's experiences, doing this releases mental energy for reuse.
You have to work through this over a long period, though, because the
stirred up energy sometimes needs time to be reprocessed by your body.
(For those familiar with Toltec traditions, this is a form of
Recapitulation. For those familiar with Chi and Taoist practices, you
could say that this stirs up heavy chi for reprocessing and reuse.
Those who have used regression may experience the processing of
stirred up energy as reliving and releasing of past painful or
emotional events. There are many approaches and interpretations that
can be applied to the same thing.)
