I'm catching up on my reading and by question to you is:
Why on God's Green Earth would you want absolutely **ANYTHING** to do with that retroactive abortion known as Xing **ESPECIALLY** in that pure excrement known as its VBR mode?
Just asking...

I have a question though, how does the gradual attenuation work?
I thought I explained it succinctly, but I'll try again. :-)
Whenever clipping occurs, the peak clipped value is examined and a new attenuation setting is calculated. Previously (or with the "Most"
sensitivity
setting) the new attenuation is one that would have avoided the clipping entirely. This can cause sharp drops in the output signal level that may
not
be desirable, especially if it was only a few clipped samples.
With a less sensitive setting, the new attenuation is somewhere between
the
previous setting and one that would avoid the clipping entirely. This
way, if
clipping continues, the attenuation will gradually still be increased to
the
point that clipping no longer occurs.
Once increased, the attenuation is never decreased unless the "Reset"
button
is pressed in the Statistics tab.
Ah, that clarified it. I just wanted to know where that "between" point was for settings less than Most. This question sort of went along with my "do you need all those gradations?" I think a Most and then a Least and Moderate setting is all you'd really need. But I think 8 gradations is overkill, and doesn't offer any real benefit. Yet I think a coninuously changing attenuation would be even better. It doesn't even need to look ahead, like the limiter that Anthony is talking about.
Is all this pre-releasing building up to a Christmas day present for
all
the devoted good little MAD users out there? If so, reading Xing VBR headers is on top of my Santa list!
Santa is making a list and checking it twice. ;-)
I'll be sure to leave out my virtual milk and cookies!
