low level sound file access somehow?

hello,

how can i get low level access to sound files? with images you can access them on a pixel by pixel basis knowing where in the image the pixel is and the value(s) of a particular pixel, once having found out the format details. how can i go about that with sounds?

is it possible to do that for numerous sound formats using core audio? (core audio, one of who's features is to act as an in between, hiding details/particulars of various sound formats from you right?) i'm not even completely sure what the basic parameters of sound are. with images you've got so many pixels by so many pixels all of which are a particular depth and the number of channels (the number of values per pixel). does core audio allow you to get that type of information about a specified sound file, and then access it in the kind of basic, raw way i'm describing? if so roughly how, if not any suggestions how to go about that?

so what i'm hoping for is that core audio can kind of channel various sound formats into a standardised basic format, shielding you from various sound format (aif, mp3 etc) details, give you the "dimension" details of the particular sound you're looking at, and then allow you to access that sound "pixel" by "pixel".

any ideas / pointers to relevant documentation much appreciated.

thanks, ben.
