New bass clipping trick: More punch. See new 'Clipping delay' slider in Loudess -> Distortion section. At 0 it's equal to version 7.00, values around 0.040 or so should be good, not sure how much higher you can go yet. Basically, whenever bass kicks in, the first (this time) it's clipped at 0 dB instead of the configured clipping level.

First test with Loud-D preset I'm seeing +1 dB in the lowest frequencies during bass punch.

And why at 0 db the first but not at configured level ?
It`s a kind of the effect of MB when bass stops and is back ( not the first but first two seconds are loud , then goes down ) .
Are you telling us the same ?
And why in version 7.00 . is it the old style clipping with the "logarithmic" view. As i remember you change it to some kind of "linear rising" style ?

The idea here is to never have these loud cuts and then "normalize" of whatever part of music we talk about ( bass, mids, highs ). If you have these cuts it tells listeners for a bad equipment :(

@DJ-Doggy

The Clipper delay is in mSeconds.
Normaly this gives somewhat more bass punch.
It was not availabe in former versions, so when the delay is 0 mS, it sounds the same as in V7.02

In the big Orban boxes the same effect is done by setting the BASS atack time at band 1 at about 35mS, this can only be done without negative effects when the so called bass clipper can be set at MED or SOFT (8300/8400/8500/8600)

Same with more config options and better behavior and control:

I think (after doing some tests) that the response speed must be set higher - around 20 Hz seems to be good. Make sure to avoid using that without using a HPF at a higher freq then 20 Hz (30 Hz is probably good) or you'll get really bad distortion!

Ah.

First, what this filter does is increase the clipping level if there's a sudden increase in the amount of clipping.

Now say you play a tone of 10 Hz, and the response speed is also set to 10 Hz. At the first top in the waveform, that's a big rise in clipping, so the clipping level is increased. Now, when this top is gone, the clipping level used for calculations is reduced (similar to what happens in a compressor); and since the response speed is set to 10 Hz, the moment it reaches the bottom of valley that comes after the peak, the level would have dropped far enough to allow another peak to get through (but the peak is already there so the clipping level is not increased anymore).

Now if you would instead play a 5 Hz tone, the calculated level would have dropped much further and the valley - and each following peak - would again cause an increase in the clipping level.

If you don't understand what I wrote (which I can very well imagine) I can draw an image, that's probably much clearer.

An image will be more graphic :)

Drawn VERY quickly!

Top image: 10 Hz tone with 10 Hz response time - only first clipping is ignored.
Bottom image: 5 Hz tone with 10 Hz response time - as you can see the 2nd one is not completely clipped anymore. Same thing will happen to 3rd etc.

For both images, the bottom display shows the amount of clipping; the green lines follow the clipping level and determine whether clipping will proceed or be ignored. Green line steepness corresponds to response speed!
