soundin will read samples from the input file at the 
performance a-rate (same as sr).
If this is not the same as the original soundfile sample
rate, pitch will change. 
diskin to the rescue: try something like

    ; assuming sr of the original file is 48 kHz
    aL, aR diskin "myLittleBleep.aif", 48000 / sr

perhaps.
