Re: [MacPerl] File reading ?'s

[Jeremy Lee <jeremy@cdsnet.net>]

SD2 files contain only a single sound per file.  The problem (in this 
case- in others it's a blessing) is that the information about the sound 
is all in the resource fork.  I can't get access to it with a simple read 
statement, but have to use the Mac Toolbox routines.

The resources I need to look at are:

"STR ", "sample-size"
"STR ", "sample-rate"
"STR ", "channels"

I can see these resources in ResEdit, and they are really straight 
forward.  But I can't seem to get the string values of these resources.  
Anyone have any suggestions?

Thanks again for everything,

jeremy
