I am writing a little offline editing framework for soundfiles and to make
things easier on load i convert the sounds to the canonical format wich,
afaik, is 32bit float interleaved linear pcm. i had a problem displaying the
sound until i found the data after converiosn (CAconverter api) has
amplitudes around e-18. is that normal? is there a standard normal
amplitude? whre is it defined? or is it ok if i just normalize or will that
confuse the converter for saving or exporting the data?
i couldnt test the latter part by just saving in a non float format because
for some reason audiofilecreate fails, even though the fsref is ok and the
string (a cast NSString) is rather simple, any hhelp on that would of course
be appreciated :).
regards,
Daniel Oberhoff
