GT3b2 with HF Reduction, Proof of concept Options

[QuantumKnot]

I've included the HF boost reduction technique I used in QKTune beta 3.2 into the current GT3b2, as a proof of concept.

The nice pre-echo handling of the original GT3b2 may be slightly worse. Start at -q 5 and compare this with the original GT3b1/GT3b2 and see whether the HF boost is there or not.

The second one.

When you said 'start at -q5', does it mean that we have to follow the test with -q6, -q7..., or with -q4, -q3...? (sorry if it sounds stupid, but I didn't follow HA during a whole week, and I probably miss some important informations).

That's ok.

Theoretically, these changes should reduce HF boost in all quality ranges, even though when I tuned it in QKTune beta 3.2, I used q 4. This is because the changes are not quality-dependent.

I suggested people start with q 5 because that is where the benefits of Garf's tunings start to occur so we have (hopefully) a combination of good pre-echo handling and low HF boost. I want to see if this technique can improve other tuned encoders as well, not just my own.

But yeah, my feeling is that it will work on all quality levels that use lossy stereo coupling (q < 6). So feel free to try it on q 1,2,3,4, which is the 1.0.1 tuning range (ie. poor pre-echo handling).
