 ͏    Because from my experience "libfaac" can't really handle 128 or 160 Kbps as well as "ac3".

 ͏    Both "libfaac" and "ac3" have annoying sounds at 128 Kbps.\\
 ͏    It probably depends on what one prefers. But "ac3" is definitely better than "libtwolame" at 128 Kbps:\\
 ͏    "libtwolame" completely breaks down at that rate.
 
-͏    Now I see that even "aac" has been ranked higher quality than "ac3"??\\
+͏    "Aac" has been ranked higher quality than "ac3". \\
 ͏    Also unless I had a broken "libvo_aacenc" encoder, I doubt "libvo_aacenc" beats "mp2" @ 256 Kbps: it just doesn't make sense.\\
