Stereo Tool

Not true.. i still can have bass at 100% with "Strict limit" at 0.10! ofcourse with enough ammount of punch.
Second, i reply fast because i learned how much you need for building, i already downloaded and tested.

Uh?
- Clean/Punch: Max punch
- Max punch: +200%
- Clip lowest bass at (dynamic): 0.10
- Clip punched lowest bass at (dynamic): 0.10
- Never dynamically raise bass level above: 0.10
Result: Bass level at 9.7%-9.8% at normal input levels, raising upto about 10.5% if I increase the input level to over 10 times the maximum level (so Pre Amp at x 10.0, all other filters turned off, input bass at -0 dB).

Please read carefully the interaction between 'Clip ... at' and 'Never dynamically raise bass level above' - if EITHER is set to a higher level, bass upto that level is still possible.

my error, actually i set "Clip Lowest punch" to 2.00.. so i expected anyway clip without that.
I have to set it to 0.71. dynamic, again not strict.
push to one place and down to other...

I must be missing something i can make it strict.

Can or can't?

Try setting all 3 sliders at the same value, that should be strict. How do you check if it's strict?

(Try this: Set the strict frequency sliders to 900 Hz and 1000 Hz, and use a lowpass filter at 900 Hz. Then you should be able to see that it's completely strict).


So something like this:
- All filters OFF (hit RESET)
- Enable Lowpass filter at 900 Hz
- Pre Amp high (say x 20.00)
- Turn Loudness on (value doesn't matter)
- Clip strict from 0 Hz to: 900 Hz
- then to non-strict at: 1000 Hz (NAME 'from 0 Hz upto' IN INTERFACE IS INCORRECT!)
- Clip lowest bass at, Clip punched lowest bass at, Never dynamically raise bass level above: All to 0.10.

Now you should be able to increase Post Amp to x10.00 without getting overshoots.

By the way: I just tested 'Allow more distortion' a bit more, and to me it seems to give a more open, dynamic sound. And I can't really say that I hear extra distortion. So I'll change the name.

nope..
Signal is already lowpassed at input...
None of you mention can make it strict /// BUT///


'Allow more distortion" - If i set it to +1 and...
- Never dynamically to -.40
- Then rioze to 100
- Clip punched to 200
- Clip lowest bass to 0.86

I have 93-97% bass output.

But this 'Allow more distortion" again kills punch.

Have you tested it with the lowpass setting I mentioned? Here it's PERFECTLY clipped below the selected level... So I really don't understand it (unless the stand alone version behaves differently from the DSP version; will test that tomorrow).

I just performed a different test:
- Loaded a normal preset (FM Loud Bass Europe)
- Set all 3 clipping sliders to 0.10 (10%), frequencies to 1000 Hz .. 1000 Hz
- Let it run for a while
- Opened output file
- Filtered out everything above 1000 Hz

The result clips at about 14% (should have been 10%)

Then ran the same test with all settings at 0.25 (25%)
Result clips at 28% (should have been 25%).

Then ran the same test with all settings at 0.50 (50%)
Result clips at 53% (should have been 50%).

The small errors are probably coming from different lowpass filtering etc; result seems close enough... (If I don't need to lowpass filter it afterwards it's MUCH closer).


Bojcha: How are you testing?

NOTE: I HAVE BEEN TESTING WITH THE DSP PLUGIN (I have some sound card driver issues which make it difficult to test with the stand alone version, which you are probably using). This SHOULD not make a difference unless something is crashing internally.

I use Standalone because i need that for real FM and/or stream use.
Because i test FM mode, i use MpxTool.

Winamp > (vac1) > ST Standalone > (vac2) > MpxTool > Any Soundcard (you don't need superb soundcard)

With Winamp i use ST DSP, only bandpass so i can set desired freqs in it.
Why? Because i can send same sound from winamp to BBP for example.. just fast change of audio proessors.
I can see, hear and measure in real time what happens with MPX output.
So if in BBP level of 0-350Hz is Strictly clipped (brickwall) at 95% (or less - depend on settings), it must be in a StereoTool too (if it is intended).

Ok, clear. The ST lowpass filters are not that steep (to avoid artifacts and keep them phase linear). So if you select for example to process audio upto 350 Hz, it could very well be that the strict clipping is already starting at or even a bit below 300 Hz...

What happens if you set the clipping level lower than 95% (say 50%)? How big are the spikes that you're getting? (I expect them to be non-existent based on my measurements). Do you have 'Remove DC offset' enabled? (I think - still need to check it - that that might also have some impact...


I also have a new idea that - if this is indeed the case - would fix it (and also reduce the CPU load) - the end result should still be roughly the same though. (And I think the current solution better protects the highs).
