Could someone please write down what these parameters mean?
(FL) (FR) (FC) (LFE) (BL) (BR)

How to read it? When is it good and when is not good, Does more mean better sound or does as less means better sound?

This is the result of scanning my CD

The LUFS test version at https://foobar.hyv.fi/foo_truepeak_0.6.8.fb2k-component was just refreshed.

Nice.

Just for my understanding. I removed the old version. Restarted foobar and installed the updated version.
I still see the names I entered for LUFS-S/M which are:
truepeak_scanner_max_lufs_s_track
truepeak_scanner_max_lufs_m_track.

Can you confirm that your default names upon first time installation are:
truepeak_scanner_track_max_lufs_s
truepeak_scanner_track_max_lufs_m

Thx for looking into the speed/performance problem as well.

EDIT: Sorry, let me rephrase .. What are all default names for custom fields you provide upon first-time installation?

EDIT2: You just hit one of my major annoyance points in foobar ...  the settings screen is not resizable and you have now more options than one small settings screen.

Is the Clip count based on the PCM sample value, or the True Peak reading? I am assuming the former, as I have scanned a number of albums showing TP levels of above digital zero, but the Clip shows zero too.
Clip count is calculated from the upsampled signal currently. Are you certain about clip count showing zero? That should not be possible.

Yes, using this string to display the Clip count in the playlist:

%truepeak_scanner_clipped_samples_track%

And this King Tubby CD is showing dBTP overs of up to +2.45dB on one track, but the Clip count is zero for every track.

The LUFS test version at https://foobar.hyv.fi/foo_truepeak_0.6.8.fb2k-component was just refreshed. Version number intentionally kept the same as I'm still tweaking things for public release.

There's now an option to also include LUFS-I tags when ReplayGain scanning. Album variants of LUFS-M and LUFS-S tags are now also supported.

I too noticed that momentary and short-term loudness evaluation is very slow. First test version called the calculations after each processed audio chunk. Refreshed build runs the calculations approximately every 100 ms. Sadly the results change a bit depending on when the calculations are done. I will need to tweak this behavior still a bit, I don't like that the numbers change for bit-identical data depending on how many samples a decoder produces per decode pass.

There was also a stupid mistake with SoX upsampling setup that was found thanks to @ngs428's sharp eyes. SoX upsampling mistakenly didn't use the power-of-two resampling ratio that it was meant to. Processing speed is now a bit faster as this issue was fixed.

You can merge in ffmpeg on-the-fly and pipe merged output to qaac.

What's wrong with this? :)
