What is everyone using for backups of your classical CDs? I have about 2500 that I’d like to archive… Thanks!
The best thing you can use, file format wise, is FLAC. Of course, FLAC doesn’t play nice in Apple-land but hope springs eternal that may change, eventually.
ALAC and FLAC are both lossless compressed formats as far as the audio content itself goes, but there are some deeper technical differences that leave ALAC at a fundamental disadvantage, as such it can’t be considered an archival grade format and I would not suggest you use it if you intend to make a perfect backup of your CDs you will be keeping around for the long-term.
I presume this is a task you will only want to undertake once. If you really need ALAC for whatever reason, rip to FLAC first, and convert those files to a secondary ALAC copy after the fact so you still have a proper archive to go back to.
As for ripping software, in the PC world EAC is the gold standard. It is not the easiest to configure upon first installation but once it’s set up, it’s fairly simple to operate.
In the Mac world, XLD is the equivalent software but not being a Mac user I really can’t comment on it that much.
As for hardware… yes, some optical drives are better/faster than others, but pretty much anything should be able to make a 100% perfect (veritably accurate and error free) rip of a disc, provided that it it’s in reasonably decent condition.
Either of these programs are very good at detecting/correcting errors when possible and can be configured to compress using FLAC or ALAC.
