logo.qds is 31115 bytes (30.3K) and expands to 8 seconds of 14084Hz = 112672 (110k) which is a 3.6x expansion rate (!)

very interesting harmonics, wonder if they exist filtered down?
file contains "mirrored" harmonics, wonder if that exists on other normal sound samples that are interpolated up?

half of SB init rate would be 7042Hz which is the midpoint of the mirrored harmonics

What do mirrored only portions sound like?



Disassembly of Hare Raising Havoc shows this as a transform for the audio:

It's a table lookup of a table lookup, and the tables appear to be mostly sine waves.  Each nybble would appear to be expanded into a byte, however the speech sound files appear to expand 4x not 2x, so more research is needed.
