I'm testing for differences between VBR and CBR rips at various different bitrates. I just did a VBR Normal/High rip that shows the bitrate of "Speak To Me / Breathe" off of "Dark Side Of The Moon" as "32" in the bitrate column. Is this simply the "starting" bitrate? Based on the rates shown when playing the song, it's obviously not the average, but I thought that the number shown in the column was supposed to be the average. I ripped the same song at the "Normal" setting, and it shows 142 in the bitrate column, which confuses me given that it's supposedly a lower quality rip. What's happening here?
The other question is which MC VBR setting/s corresponds to the "alt preset standard" setting that people always refer to.
Thanks,
Larry

Most likely the 32kbps bitrate is due to some sort of (possibly random) error in writing the vbr header that occurred during the normal/high rip, which didn't occur during the normal rip. There have been some posts recently about this. Most have said that reripping usually fixes the problem.

32 Is an Average.
So some parts are higher and some parts are lower.
if you play the file you should see the Kbps change in the window where the name of the file is playing.

Before reripping i would try to update the VBR-Header. If the 32 kB changes, you see it was corrupt, if not King is right.
MC has no feature to update the VBR-Header (maybe in future ?!)
You have to use a tool like:

I think Rocket likes it too ;)

I cannot see how 'Pink Floyd - Breath' from Dark Side Of The Moon can average 32 with a VBR setting like that.
And even if it was an average, that fails to explain the 'average' of 142 on the other rip . . . that should average about 24 if your theory is correct.
I'd say it appars to be either a bad rip, a bad header, or an MC encoder bug.

Now you are trying to get me to pull that CD off the shelf and rip it.

the Track Is #1
It Is Called: a. Speak to Me/b. Breathe in the Air
the total track is 3:57 Listed on the CD
MC10.0.41 has it listed as 4:00 so not sure why mc10 is listing it as 3 extra seconds, maybe a bug, maybe the cd is wrong pick one.
at any rate, when using VBR normal\high, [advanced] High Quality I got
147 Kbps

The other question is which MC VBR setting/s corresponds to the "alt preset standard" setting that people always refer to.
If you go into the configuration ("Options..." - "Encoding") and select the
"MP3 Encoder VBR" encoder with Quality "Custom". You can then click on Advanced and add the commandline "--alt-preset standard".
Personally I use "--alt-preset extreme" :)

Thank you King ;D
