Going Lossless

24 August 2009

I’m ripping CDs to 256Kbps AAC, mostly because it’s Apple’s standard on the iTunes Store. I started out in 2002, ripping to 128Kbps, again because it was what Apple was doing, but also because my iPod was 30Gb and I had to fit everything on it plus leave some space for my rapidly burgeoning collection. iPods, in my book, dictate the bitrate you will be using.

I just bought two albums from sources other than the iTunes Store: the remarkable chiptunes tribute to Kind of Blue, Kind of Bloop and a new Paul & Price EP, Believing. I like the iTunes Store’s 256Kbps, but these two titles had a killer feature–they both were available in a lossless format. I ripped both to 256Kbps AAC and stored the lossless files away for later use.

I’ve been through three bitrate standards: 128Kpbs, 192Kbps and now 256Kbps. Each phase represents a time when the iPod (and to a lesser degree, local storage) capacity increased markedly. There is another phase to come, but thankfully it will be the last. When the iPod has another great leap forward in capacity, say to 500Gb, I will make that final step to full lossless for all my CDs.

The beauty of lossless, from a management viewpoint, is that you can’t make it any better, and thus your bitrate journey is over. By lossless, I specifically mean Apple’s Apple Lossless format, because that’s the one I’ve selected for compatibility with iTunes and the iPod.

It struck me, with these two titles I bought, that I don’t need to convert them to 256Kbps. There are only 9 songs between them, and keeping the lossless versions in iTunes means I don’t have to archive copies and there is no need to maintain two versions. My 160Gb iPod Classic still has about 25Gb free, and my iTunes library is on a readily upgradeable Drobo, so there’s no need to be careful about space considerations. I wouldn’t do this with all my music yet–there’s still the iPod capacity barrier, but the distinction here is that these files do not have a hardware CD source. I might as well leave these bits and bobs as lossless. Now I need replacement lossless versions for the Neptune Pink Floyd tribute compilations None of Us is Pink and The Return of the Sons of Neptune, lost in a hard-drive accident.
