The Sound of Pi

Currently, I have coded 65536 bits of binary pi into these sound formats:

8-bit integer, 2's complement
8192 sample frames, 8.000 kHz
This sound lasts for 1.02 seconds.
16-bit integer, 2's complement
4096 sample frames, 8.000 kHz
This sound lasts for 0.51 seconds.
ouzo@redrose.net put this sound through the anti-noise filter of CoolEdit.

I'm planning to make sounds with other formats. Of special interest is 3-bit integer because the integer part of Pi is 3!

Can you hear any secret message from the Creator of Mathematics, or can you hear any variations in this boring noise at all? Tell me!
