Bitrate analyzer/viewer

Is there any bitrate viewer for vorbis files ?
Something like Encspot for mpeg layer 3 files.
I want to see what bitrate is used in the timeline and maximal/minimal bitrate used.
Thanks for advice.

Not that I know of, though only a few days ago, I came up with this idea and asked John33 for his opinion.  He said he'll look into it.

iirc such a proggy already exists. I saw it in a thread several months ago.. but I cannot tell which thread it was. it showed the bitrate of a testsample. iirc it was castanets
I love the moderators.

I guess one can easy make such a program using getID3(). This may be not the most convinient solution, though

AFAIK, that one only plotted the bitrate versus time.  What I like about encspot is the other info that it shows like proportion of long blocks to short, intensity stereo and mixed, bitrate histograms, etc.  With the Vorbis one, detecting block size on a frame by frame basis should be easy, as well as bitrate histograms.  As for measuring point stereo to lossless stereo, I guess you could approximate that by counting the number of samples which have zero angle.

Like the starter of this thread I'm also looking for a program to view the bitrate distribution of ogg-files. Is there something out by now?

I use oggspot and gnuplot for such a purpose. When I confirm it on the basis of text, I use my own vinfo.

Thanx!
Is there a oggspot for windows? I just found a .tar.gz-archive and I guess thats for linux, isn't it?

My own vinfo got possible to output the change of the average bit rate.
It can become a graph by using gnuplot together.
