Hey Bill,
are you saying I don't know how to code up an AIFF file parser? I
already did this at a time where the only sound file format my Mac
would recognize was some strange thing called a "System 7 sound" ... :-)
Alright then, since you brought it up: as you know, ExtAudioFile
doesn't exist on certain handheld Apple platforms (let alone platforms
other than Apple!), and quite frankly, (Ext)AudioFile can be a pain in
the butt to use (*especially* ExtAudioFile due to its lack of
multithreading support). I'm pretty sure I'm not the only here one who
had suffered a headache from using it one time or another...
Take a look at the miniAIFF API ( http://stephan.bernsee.com/
MiniAiff.h ) which essentially uses the fopen/fwrite/fread syntax -
you can't make this any easier, especially when thinking about cross
platform compatibility (which is what this was designed for in 2003).
I am using ExtAudioFile for all audio I/O in our commercial products,
but for demoing new technology where all you need is a quick and easy
(ie. readable to people who don't know what an ABL or ASBD is) and
cross-platform way to access sound without cluttering the code I
usually prefer miniAIFF.
Best wishes,
Stephan

I've no idea why you guys are doing this when AudioFile already
exists and does exactly this. The API is pretty straight forward and
we'll be happy to answer questions about its use. Its difficult to
know how to respond to a "I don't get this" complaint, which is why
you've not seen any responses from us previously.
We've seen in general more problems with these minimal file parsers
making all kinds of incorrect assumptions about the file layout, and
consequently many bad files as a result.

Hi François,
I am in the process of updating the miniAIFF lib and releasing its
source code on www.dspdimension.com. Email me off the list if you
want a preliminary copy that compiles on the iPhone.
Best wishes
