Dynamic range utility/plugin

Is there an add-on utility or plugin available to calculate the dynamic range of tracks?  The results would be something similar to the numbers produced by the TT DR software promoted by the Pleasurize Music Foundation - although the numbers produced by that utility look nice, the user interface is cumbersome when looking at multiple files, especially if they are in different folders.  Ideally a foobar add-on would be invoked in a manner similar to ReplayGain with an option to save the results to a log file.

I don't think there is anything, that's why I wrote a program in AutoIt that automates TT-DR scanning. It works like this:

1) Drag'n'drop folder containing flac/mp3 files (or folders of files)
2) The folders are converted to wav files in a temporary folder one at a time
3) The wavs are each scanned into TT-DR automatically
4) TT-DR values are logged and the original flac/mp3s can be tagged with the TT-DR (track and album) values

Actually it scans each track twice: once in "file" mode (so the dynamic range provided is to 2 decimal places) and once in "folder" mode so the TT-DR album value can be calculated.

There is then the option to use TT-DR's album value (I can't work out how this is calculated), or a weighted average of the track TT-DR values.

There is also an option to use the maximum TT-DR value for both channels instead of a simple average (as used by TT-DR).

There are a few shortcomings: 1) only 44kHz/16-bit input is accepted 2) mp3 tagging is glitchy, so it tags a copy of the original 3) It relies on simulated mouse-clicks and keyboard presses so you shouldn't multitask while running it.

I successfully scanned my entire flac collection overnight. It's fun to sort my whole collection by TT-DR and really hear the difference between dynamic and compressed music!

If you're interested I'll tidy it up and post it here.
