What're the best settings for encoding mp3s?  I have --alt-preset extreme/ q 0  in there right now, is that correct syntax (with those spaces and everything)?   I don't think it is because it is freezing up MC every time I try it.
Any recommendations?

Try:

--alt-preset extreme -q 0

It should be just --alt-preset extreme

Have no idea what the "/ q 0" is...but it is unnecessary.

Using standard will reduce file size a bit, yet still maintain high quality. Extreme may do better on harder to encode material.

* -q 0..9    algorithm quality selection

Bitrate is of course the main influence on quality. The higher the bitrate, the higher the quality. But for a given bitrate, we have a choice of algorithms to determine the best scalefactors and huffman encoding (noise shaping).

    -q 0: use slowest & best possible version of all algorithms. -q 0 and -q 1 are slow and may not produce significantly higher quality.

    -q 2: recommended. Same as -h.

    -q 5: default value. Good speed, reasonable quality.

    -q 7: same as -f. Very fast, ok quality. (psycho acoustics are used for pre-echo & M/S, but no noise shaping is done.

    -q 9: disables almost all algorithms including psy-model. poor quality

There is no point in using -q x with the presets...they already include the optimal value

I have seen a -q switch in some encoder software I used to use, which denoted quality, however with the string presented here I expect that Xen is correct and it is unecessary.

If you are THAT concerned about sound quality why not give APE a go? With the price of harddrive space these days it is worthwhile if you are ripping.

Well, the "-q 0" actually did work.  I read here http://www.ipodlounge.com/forums/showthread.php?s=&threadid=8360 that it had the best quality sound (4th post down, RandyP).  If it's not necessary though, then I could leave it off.

Thanks!

Thank you xen-uno and LisaRCT!    I have it ripping and encoding separately, next I'll try it simultaneously, see if that works!

--alt-preset standard. Prove it if you can really hear a difference.

I have --alt-preset extreme/ q 0

Why? See above.

If your looking for something that wastes bits for no real gain then keep doing what you're doing. If you demand even better try lossless.
