The analysis is using the Dynamic Range Meter.

The plugin from the above website has expired. A working plugin for Foobar is available from:
Dynamic Range Meter

I've been using it for some time now. It's quite nifty.

I just looked at one in the database that I have. The Lyle Lovett album "I Love Everybody". Seems to have good dynamic range.

DR Database

The database says a DR average of 15 for the album.
My software (Goldwave) says most tracks have an RMS value of -22dBFS

Which is right?

DR15 is a rating based on the entire track. It is not the RMS value for the track. If you download the foobar app, you can get the RMS and peaks for each track through the tool, and it will also provide a DR rating. Also, some tracks can have a low RMS but the peak is also low, in which case it's not as dynamic as when the peak is close to 0 db.

The DR rating just gives a number to compare with other tracks. You can analyze an entire album and it gives a single rating for the album too.

So DR10 is worse than DR15, and so on.

Just checked your link. All the songs in that album have a high rating, which is good.

You should start a thread for your favorite genre.

Well then I don't understand what DR means. Isn't it Dynamic Ratio? How is it calculated? It's a ratio of what to what?

I would imagine it is the difference between the softest and loudest parts in the song or album.

Yeah, I suppose it must be. Wonder how it determines that? What constitutes a part?

Anyway for me, the RMS value of the track gives me a good indication of the dynamic range. Most tracks hit 0dB at least a few times. Some very soft tracks don't, of course.

It most likely looks at where the signal is the lowest, and compares it to the highest peaks. This is all you really need to tell the dynamic range of a song. From there you'll have to average it out when you take a whole album into consideration.

If that's the case, then I think the tracks I looked at would get a higher rating.
Maybe I'll have a stab at some test tracks to see what it tells me.

It could be an average of the highest peaks to the lowest peaks, which will give you a lower value than a single measurement of the very highest peak to the very lowest.

This would be a good way to do it because, think about this....
Even if a track is completely brick walled, if there is a moment of complete silence, then that would give a very large DR measurement if they weren't averaged out.
