I don't recall if the M/S switching threshold changes with bitrate. If
not, this might be a good idea to impliment, and will make M/S more of a
winner at 'maby' bitrates of 160.
As far as the safeness of CBR vs VBR, you can set min/max bitrates:
-b 160 -B 224 which will make you much more 'safe' with VBR. You will get
a higher bitrate, but you'll be sure that a sudden cymbol hit won't get
audioable artifacts.
It would be nice to be able to adjust the analog silence threshold ratio
though, because you still run a slight risk of it thinking there is
silence on a recording that is simply ment to be played loud. :)
Personally I'd like lame to use sound profiles, but I'm too busy (lazy
too?) to code it:
I.e.
archive1 {
mode = vbr;
stereo = joint;
minrate = 160;
hardminrate = 32;
maxrate = 224;
lpass = 22050
hpass = dc;
noshort = 0;
msswitchr = .25;
analogthreshold= 0.0;
quantcomp = X4;
fullsearch = 1;
};
In a lame.conf file..
Then encode with lame -mode archive1 in.wav out.mp3
