Try the freeware XLD (X Lossless Decoder) it works very well.

AIFF is about 10Mb per minute, which means that your 9 1/2 hour recording will 
require (9*60+30)*10 = 5,700 Mb or 5.7 Gb of space, roughly. This leads 
directly to this data point, from the Audacity documentation:

"Note when exporting your recording that there is a file length limit for WAV 
and AIFF files. The file size is set in the headers as an unsigned 4 byte 
integer, which imposes a 4 GB limit, except that some media players interpret 
the file length as a signed number, which imposes a 2 GB limit."

It would appear that iTunes splits the difference :-P

Audacity itself has a limit of 13.5 GB per recording (in native audacity 
format, how much audio time that corresponds to depends on the sampling rate), 
so you might try importing the original recording (in whatever format it's in) 
into Audacity.

You can also (laboriously) split the track into chunks in iTunes itself :

Why not open that file in Audacity ? however don't be surprised if 
Audacity also chokes swallowing all that data.

iTunes truncates when converting

2011-04-21 Thread William Spencer
Hi there: I have a single audio file of about 9 1/2 hours duration, that for 
some unimaginable reason I want to split up into smaller chunks. But when I 
tell iTunes (10.2.2) to convert it to AIFF so I can edit it with Audacity, 
iTunes stops the conversion at well under three hours, and truncates the file. 
What's going on and is there a workaround? As always my thanks in advance!
