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 : <http://www.dummies.com/how-to/content/modifying-songs-in-itunes.html> -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.
