Creating a log of the written MP3 file in EAC

So I've been using an early 0.94 version of EAC to rip some CDs and as the Lame box pops up to show what percentage of the MP3 is being written to what bitrate, it occurred to me I'd like to see what's being displayed permanently in a text file.

I was testing various versions of Lame from 3.98 to 3.100 using V0 and the resultant MP3's have varying file sizes. I noticed when Exact Audio Copy triggers Lame and it converts the WAV file to MP3, some of the Lame versions weight the bitrate to the midrange in the 200Kbps, and some of Lame versions weight the bitrate to the high-end either side of 300Kbps.. they're not all being written the same.

So I've got a number of MP3's of the same song and I can't see what particular Lame versions have weighted toward the midrange or the high-end. So I wondered if there was a way to log the results to a text file? Does anyone know if this is achievable?

I don't know how to log the information.

The lame version may make a difference but the program material also makes a difference.   (Some sounds are easier to compress than others.)   So you'd need to compare the same CD with different versions of lame.   At V0 you probably aren't going to hear any difference even if one version gives you a slightly different bitrate.

Joint Stereo (which should be the default) should give you a lower bitrate than regular Stereo.   There are some other settings that can also make a difference.

If you want a known-fixed bitrate you can use CBR or ABR.     With CBR/VBR Joint Stereo should give you better quality (although it can't be "better" if it's transparent and sounds identical to the uncompressed original).

With VBR you choose the quality setting and lame chooses the required bitrate moment-to moment needed to hit the quality target.   Silence and "simple sounds" give you a lower bitrate than complex sounds.
