Sound programmer/Specialist In Sound Manipulation

I need someone that can work with my current programmer to manipulate individual bytes of data to manipulate the High/Mid and Low tones of a note As far as my programmer is aware there is no API to manipulate the High/Mid and Low tones of a note in flash/actionscript which is what we need to do. I need the bidder to have extensive knowledge of manipulating individual bytes of sound data and be able to work with my current programmer to incorporate this feature into my software. Please only bid if you have extensive knowledge of how to do this and also extensive knowledge of how to incorporate it into flash/actionscript.
