The easiest way to speed something up without changing the
pitch (over small increments, anyhow) is to use something
called a variable-speed oscillator. A commonly used version
of this is a device called a "Harmonizer." It allows you to
raise or lower the pitch of a signal, and to mix tyhat pitch
in with the original signal if you wish. Check out the chorus
singing Adrian Belew does on "sleepless" from the new King Crimson
album for an example of one. In my work , I used them to create
pitch shifted "melodies" from single fragments of tape. If
you shift the pitch of the signal up too much (say, a fourth
or fifth), you get the upper harmonics to do funny things. My
engineer pals called it "munchkinizing"...prosaic, but to the
point.

Hope it helps.
