Converting to AAC? Get comfortable.
For disk space considerations, and for the sheer tweak factor, I'm copying/converting 1400 of my 192k mp3s to 128k mp4s for use exclusively on my ipod. (I'm all for trading a little sound quality for a few more gigs of space.)
I did a little research before starting the project, but no where did I find anything mentioned about the amount of time involved in converting this many files.
I began the conversion (using dbpoweramp and its myriad of separate doohickeys to make the process work) and sat there for a while, watching the progress meter. It didn't move. I went to the bathroom and came back. Still 0%. I went to lunch and came back half an hour later. It was still 0%, but it said 10 or so files had been processed.
I stopped the program and went into the preferences, looking for a "ridiculously slow" checkbox or something. I couldn't find anything like that, so I assumed I'd set us up the program correctly.
Some time later, the progress bar finally reached 1% and displayed an estimated completion time of 48 hours. Yes, like the show. 2 days. The lifespan of a mayfly. I had no idea what I was getting into.
That was yesterday at noon. The program hung overnight for an undetemined amount of time, and again a couple of times today. It said it was unable to access memory for some reason. So I lost some time in there somewhere.
All I know is, I have 480 files left to convert, and the countdown says 15 hours. I think that's sometime in early September.
Meanwhile the computer is not happy. It's developed a slight cough and won't let me run much else. I tried to play Unreal Tournament, but it just laughed at me. When this is all over, I'm taking it out for ice cream.
In the end, I hope to gain at least 10 gigs out of the deal and another story to help solidify my friends' theories that I really need a girlfriend.
Oh, and why am I writing this? See above.

you lose quality when you convert from one lossless format to another lossless format, which means ACCs converted from mp3s are going to sound worse than ACCs converted from wav. So Rob I'm not sure if you did a sound check to see if you like how the files sound, but just be warned you'll be losing extra sound quality. I've never tried it though, so I hope its not too much. Good luck.

See, that's why I wrote a script (winxp) to have itunes do them all for me... I just ran it overnight and it worked without a hitch, I even had it copy over my playcounts and last time played, too, so I didn't lose the data with the new files.
If anyone is interested, email me at jasonlustig AT adelphia DOT net and i'll send it to you.

*its lossy, not lossless (this is for music that has no loss in quality and its uncompressed)
