| Doug, Tahome, thanks for your hints.
MiniAiff looks cool but I need some more informations like velocitiy values and loop markers out of the aiff file. So I got it working with the Audio File Services now.
Thanks Peter
I'm using miniAiff in my project which can extract this information from the AIFF file: http://www.dspdimension.com/admin/miniaiff/Far more easy to use than the Apple API. --th

Hi all,
I'm using the Audio File Services API to get information like loop markers
and so out of some AIFF files .
For marker informations one can use kAudioFilePropertyMarkerList.
But how can I get the root key ( the midi key that correspond to the
original pitch of the AIFF file like e.g the EXS24 uses it )?
It looks like there is no chunk for that.
If you use AudioFileCountUserData / AudioFileGetUserDataSize /
AudioFileGetUserData to walk through the chunks, do you encounter the
InstrumentChunk? (see the ancient AIFF.h)
