The tool - Amplitude Statistics - provides a lot of useful information, in a pop up window.
I'd like to be able to use the LUFS value in an external program (to adjust volume control)
But to do so, I need to extract this value for each song.
Is there a way via batch to run the Amplitude Statistics function and have it's output placed in a file, or ideally just append the LUFS value to the file name? Doing this manually is just not an option. (over 800 CD's)
I do not want to change the file, just know it's LUFS value.

Re: External access to LUFS value
Unfortunately there is no way to do that in GoldWave. Maybe there is a command line program out there that can do it?
Re: External access to LUFS value
Thanks, can you suggest where I might learn how that value is extracted from wave file?
I've written a couple of programs that read a .wav file and have modified it, so I'd give that a try if I knew more about the logic and how that's calculated.

This Wikipedia Page has links to several related technical documents.
I also found:
github.com/jiixyj/loudness-scannerv

Audacity now has "Loudness Normalization" and it's open source so you could dig-into the code. (Audacity won't show you the current loudness but of course it has to be doing the calculation behind the scenes.)
