So far I have tried Audition 1.5 on THREE computers with the same result: my client’s file cannot be edited, but smaller files, including smaller pieces of her file can. All machines have PLENTY of RAM and hard drive space. (Wouldn’t Windows give its usual “out of memory” or “out of virtual memory” messages if either of these were a problem?). The best machine has the following specs:
AMD Athlon 3200+
1GB RAM
160 GB hard drive (in RAID 0 array) 80% empty
WinXP Pro SP2 + all updates
I can make one, or sometimes two small select-and-deletes before the problem happens on this machine. If I edit a small section of the file (say three minutes) I can edit freely. I haven’t had time to test what the actual maximum file length that can be edited is, but it is certainly MUCH smaller than both the available RAM and/or the available hard drive space. Again, shutting off resource hogging stuff (Like Norton AntiVirus) has no effect.
The other machines are almost as capable, differing mostly in processor speed which should merely make Audition run slower, not hamper its capabilities. Users have no problems with any other program on these machines including Autocad, and various video processing apps, all of which are very machine intensive.
As far as contacting Adobe, they DO NOT RESPOND. This is my usual experience with most software vendors, so they, perhaps, do not deserve scorn. (But I doubt if I will buy from them again, unless this problem can be resolved)
