Hi all:
Forgive me DEX for messin with your audio clip. I slowed the spped
by 40%, and then raised the pitch by 49% to get the audio back as
close to 1000 cycles as possible. It most definitely is a 1000 cycle
data encrypted tone. At the slowed down rate, you can easily hear
the bit rate encoding of the signal. Listen to it if you like:::
