Hello all. As you can see, I'm new to the boards, but have perused them as a guest for some time.

I'm still trying to learn the ins and outs of audio archiving, and after doing considerable reading I've started archiving my CD collection with LAME, using the -V0 and -q0 (highest quality VBR) settings.


I have two (potentially stupid) questions for those more experienced than I:
(1) Do you see any point in recompressing my CDs using LAME 3.99.5? The vast majority of them are already compressed with 3.98.4. 3.99.5 seems to give a small file increase on the higher quality settings, but I'm really only concerned about the audio quality.


(2) I've noticed that LAME VBR always uses MPEG 1-Layer III bitrates (32, 40, 48 ... 320), presumably because CDs are always at a 44.1kHz sample rate. Would it be possible to combine MPEG 1 and MPEG 2/2.5 (8, 16, 24...144, 160) bitrates in the same file? If so, would those be readable by most players? And what about using freeformat options e.g. 288 or 640 kbps?
I'm thinking that allowing MPEG 1 and MPEG 2/2.5 in the same file, if that's possible, would allow VBR files to be a bit smaller with no quality loss - since silent sections, for example, could be encoded at 8 kbps instead of 32. And it'd be nice to have freeformat options above 320 kbps available since this is for archiving.

Why in this day of cheap storage would you "archive" in a lossy format?

Why if you have already decided, not only to "archive" in lossy, decided to "archve" in the most audibly problematic of lossy formats? To the point where you're pissing over the most insignificant of details.

An expensive external hard drive is $200 for 1TB

That should hold ~2500 FLAC rips if my math is correct.

You want two drives (one for backup).

That's sixteen cents per CD to store in FLAC.

Mind you it would be only a hair less than half that to do it in MP3.

So we'll be generous and say the delta is ten bloody cents per CD rip...

EDIT: Forgot a key word. wink.gif

Heh, I should have guessed that the first response would be questioning why I went lossy instead of lossless!

There are two reasons. First, the near-universal compatibility of MP3s; and second, because frankly I can't tell the difference between a -V0 -q0 MP3 and an AAC or ATRAC, even when it's played on high-end equipment. I've tried--several times--using ABXY tests. Though to tell the truth, I may redo everything in AAC, ATRAC or FLAC before I'm done anyway.

So...just humor me on the MP3 questions, mkay?

EDIT: Thanks for the responses Ivqcl.

1 - If you can't hear the difference why are you splitting hairs about fringe behaviors of the encoder?

2 - If you can't hear the difference why is a 640kb frame needed?

3 - If the near-universal compatibility is really a reason why are you asking about incompatible variants?

Rip to lossless, and transcode to lossy upon transfer to your DAP/Phone/Car for the next fiveish years. After that your portable devices will hold enough to make the transcoding step unneeded.
