I have audio files larger than 100GB. Do you think you can fit those into memory?

Hi everyone,

I am working on a DSP project where I have already implemented code that
allows me to supply a buffer of samples, and it will output them to the
device speaker.

The next thing I need to do now is read in all the samples from an AIF
file into memory so that I can perform various operations on them... I
am using the "Learning Core Audio" book as a reference, and the
author's example for reading an audio file and playing it makes use of an
AudioQueue, which I don't think I need to use...

My question is, what is the easiest way to create a buffer large enough
to hold all of the samples in an AIF file and read those samples into
that buffer?

Thanks.
