Speculation On a Lossless iTunes Store

DrJenny writes "C|net UK has up an interesting blog post predicting that within 12 months Apple's iTunes Store will include a download center for lossless audio. This would be a massively positive move for people who spend thousands of dollars on hi-fi gear, but refuse to give money to stores that only offer compressed music — they could finally take advantage of legal digital downloads. The article goes into details on how Apple's home-grown ALAC lossless encoding relates to FLAC, DRM, and the iPod ecosystem."

Finally...an archive format

[TimSee]

Hope this happens. After transcoding my CD collection to FLAC to arhive it, I now regularly batch re-encode to smaller and smaller bit rates using new releases of lossy encoders. AAC has gotten much better (esp AAC-HE) over the years to the point for a portable player, 48kbs is perfectly acceptable to my ears. With a 16GB iPod Touch, I could see buying music from the iTMS in some lossless format and transcoding to get my entire collection all on a small, flash memory player.

If you're converting to mp3, and have an operating system that supports FUSE (GNU/Linux and FreeBSD are the ones I know about), take a look at mp3fs - it's a virtual filesystem that will encode from lossless to lossy on the fly. It's great for putting stuff on a small flash memory player.

Once, when my band was recording to a digital medium (a RADAR 24-track hard disk recorder, for those keeping score), we captured some tracks at 16bit, and some at 24bit. All other parameters in the signal chain were held constant.

I did not expect to hear as big a difference as I did. 24b absolutely crushed 16b in the oh-so-unscientific terms of listening enjoyment. Everything, especially the cymbals, sounded clearer, less harsh and brittle, more defined. We had to throw away some good 16b takes because they sounded so much worse than the 24b recordings.

Don't be so quick to discount the difference that a little extra dynamic range can make. Sure, you might not notice when you're listening to your iPod in your 89 Chevy Cavalier with the burned out left rear speaker, but it's not as hard to tell as you might think.

I know two audiophiles - professional audio mixers, to be exact, who absolutely have golden ears. They listened to a CD of an album master and frowned like something was wrong. The "image" wasn't right; "smeared" somehow. Turned out they could hear the difference between a master CD and a copy of the CD. The difference? Clock jitter. Yes, they could hear the effects of clock jitter. Both of these guys are legally blind which apparently sharpens other senses.
