You are basically handicapping yourself with several factors.
First you are using a laptop and while processor speeds of some laptops can be credibly fast the optical drives that are typically installed in notebook computers aren't.
Yours might be, but....
The second is from the context of your post it seems to me you are "ripping" and "compressing" in a single operation.
It might be more efficient to use ANY desktop computer and a FAST optical drive, with dedicated ripping software then doing the compression as a seperate operation.
Frankly while lossless compression allows you to expand the compressed files back to wave to burn them to disc as cdda files
without loss, but it really isn't necissary in terms of quality
to use lossless compression
And even though you are "all apple" I'd recommend some other
form of compression that is more flexible Either FLAC or even a lossy compression like mp3 at a high bitrate.
The issue with the apple compression is that they are generally written only by apple and their software geniuses while good
don't seem to have prioritized on making the operation FAST.
Apple making home rip and compression software FAST is
a comnflict against their own interests inthat they'd rather sell you the same files already compressed via iTunes.
I could be wrong, but....
on an older PC, a 2.6GHz Pentium 4, not even a dual core machine, I can actually "Rip" a CD with CRC confirmed accuracy in a little over 2minutes (typically 2:15-2:20), compression to 320kBit/Sec takes scarcely longer, typically 2:45
I actually do my compression in large batches while I'm not actually at my computer.
Frankly I NEED to be at my computer to feed it CD's when ripping
but to read several hundred wav files and create mp3's (Or AAC's)
doesn't require you to be sitting there... So the last factor is likely your operational proceedure... if you concentrate on doing what you need to do while you are sitting at your computer and planning for letting automated proceedures take care of themselves....
then there is deleting the no longer necissary wav files, moving the files to the properly labeled directories, and the great "fun"
of correctly tagging the files.... so title artist track number are all correct....
To do a single album correctly for the whole process takes
me slightly under 10minutes, of course that can be streamlined by seperating the rip, compression and tagging operations
for efficiency's sake....
As each phase of the process requires a slightly different mindset to be done efficiently, so it's best to seperate them to different times.
The conversion software I use will also create aac's and it's the "free" sample version of NCH "SwitchSound" (downloadable)
But I don't know if it'll run on a MAC Or what non-apple software might be available that will run on your mac.
