Most reliable lossless/v. high bitrate lossy format for arch

Hi
I was wondering what is the best encoder for fitting about 4 albums in a 700 MB CD-R and to keep it as losslessly as possible?
Thx

I would try Monkey Extra High and see if it fits.

Or, for lossy, use MPC Insane.

MPC "--insane --nmt 16 --tmn 32" should do the trick. 5, 6 albums per CD, and outstanding sound quality (for a lossy codec).


edit: from encoder version 0.90s on, the commands are prefixed with "--" instead of "-".

I'm unclear as to what exactly "nmt" and "tmn" do, and the help file didn't seem to shed any real light...
It's is not, it isn't ain't, and it's it's, not its, if you mean it is.  If you don't, it's its.

Would this setting be enough for re-encoding to decent sounding MP3 or OGG afterwards?

"-nmt xy" adjusts the so-called SMR for assumed "noise-like" (non-tonal) signals, and "-tnm xy" defines the SMR for assumed "tonal-like" (sinusoidal) signals.

SMR means "signal-to-mask ratio", which is the "space" between the maximum level of loudness and the threshold of allowed noise. During the encoding process, a specific amount of noise is introduced, but this noise is not audible if the signal-to-noise ratio (SNR) can be kept higher than the SMR. SMR defines perceptual importance, so to speak... i.e., the higher -nmt and -tnm, the less unwanted noise is allowed.

In -insane, the nmt value is set to 9 dB by default, and the tnm value to 24 dB. You may even raise it some more than -nmt 16 -tmn 32, to get only 4 albums on one CD, but that wouldn't make sense anymore... you should go lossless then. With "-insane -nmt 16 -tmn 32" you should already have bitrates of more or less 300 kbit sometimes..

Most definitely. But as you know, it's always better to re-rip than to re-encode...

Well, hopefully Vorbis has that bitrate peeling in there, so all we'll have to do is go "oggpeel -q 4.00 foo.ogg -o bar.ogg" with those -q 9.00 that people are probably ripping right now.

Lossless is no good. It only gets compressed to about 60% and that would only be enough for about 2 albums.
I guess I play with the nmt and tmn values so that I get the 700 MB I want to fit everything in. Or maybe simply burn it losslessly in two or three CDs. 
Thank you for your help, CiTay.

Why not just use two CDs? They're what - like a dime each? So you're spending a nickle per album to archive them PERFECTLY. Why even risk artifacts for a lousy nickle?

Not to mention that this is assuming that every CD is ~60 minutes.  2 60 min. CDs would fit comfortably within 680 MB at 40% compression.

Then again, the CD I'm listening to now is 72 min, so it might not be a bad assumption.
