Two stupid(?) questions about LAME

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.

If compatibility is what you are worried about then flac is the most compatible.

You can not play flac on as many devices but it has a FOSS license that allows it to be compiled and distributed for any platform and it can be included in other software as well.

No matter what computer platform you use, you will almost certainly be able to get a legal and free flac encoder / decoder that you can then use to create whatever lossy format you may need.

MP3 is controlled by software patents that are a problem in some countries like the US. These patents still have about 5 years left on the last of them.

This patent issue prevents mp3 from playing on some platforms. For example, FireFox and Opera will not native play mp3.
Like flac, you can get free and often legal decoders for any platform so you can transcode as needed. If you had a need for your audio to play in Opera you could transcode from mp3 to Ogg Vorbis. But that's lossy to lossy. Go with flac and your flac to Ogg Vorbis is lossless to lossy, which is better.

Even though not as many hardware players support flac numerically, it still is the more compatible format because when the need to transcode does arise (and it always will at some point) it decode of the flac is free and the transcode does not involve lossy to lossy.

flac also supports better tagging than ID3 (used by mp3) and is thus superior for archival purposes where you want information about the file stored with the file.

That seems like a few steps backwards when compared with the compatibility (across software and devices) that mp3 (and even mpeg-4 AAC) offers. I would even question the validity of saying that FLAC is the most commonly supported lossless format since the majority of portable players sold are made by Apple and natively work with ALAC (not to mention third party support across various devices and programs). I am not trying to question FLAC at all but rather I don't understand how it can offer greater compatibility over mp3 especially since every single portable audio player, smartphone, Blu-ray player, computer, the two main gaming consoles (soon to be three), tablet, and the majority of dedicated DVD players (if people are still buying those) all natively work with mp3 files whereas a small percentage of those work with FLAC.
