Notably, the high speed morse sound was super interesting, as I might like to track down a few more samples of it.

When I drop one into this decoder, it's having trouble with it for some reason: https://morsecode.world/international/decoder/audio-decoder-...

In case you were curious, one of the morse sound effects (http://bbcsfx.acropolis.org.uk/assets/07069047.wav a high pitched oscillator) translates to:

"P D F H X S T P H I Z UFR U TE4 F 4 L U V X G H I B J AU G G H Q Y P 8 0 P X Y U H B C A X JE P TI F H S T N PH ILK F G WUZ W Z UEI K S"

which seems like a cipher of some sort.
