2) I want to use the Extreme standard (when I did some blind testing, that's what was transparent to me). I'm not concerned with encoding time, so I assume Extreme will give better quality than preset fast extreme (due to artifacts with the 'fast' setting). I currently have "--alt-preset extreme %s %d" as my command line option. With Lame 3.97b1 can I just leave it as that?
With 3.97b, "fast" does not mean "faster at the expense of quality"...... there were even some reports of cases where "fast" did result in better quality.
The difference between fast and non-fast is that non-fast uses the older VBR-algorithm, while fast uses the newer one. Because everything currently points towards fast being at least equal to non-fast in terms of quality, there were some discussions about making "fast" the default, and abandon the older (non-fast) method - but it seems currently that the lame devs dont want to do it *yet* (probably because they want to do a bit more testing to be absolutely sure).
So to make it short: "fast" basically means "new and potentially better", while non-fast means "old but thoroughly tested"
