Hans, I have difficult question, every band is processed at input sample rate e.g. 44,1kHz?
Yes.
What do you think about upsampling x2 for last band? I can't imagine good processing on few samples per period...
To detect inter-sample peaks you mean? Or to avoid distortion? (I don't think it would help to avoid distortion btw.)

Simple or Basic, referred to control the speed (which influences Attack, Hold and Release), Energy or Density (Thresholds, Knee, Peak / RMS Ratio), Mix (Band Mix)
You mean all these settings per band, or a single "Density" setting? There's already - even in Simple mode - the Drive and Output level, which I think should be enough for that (because: How would a Density slider affect Knee for example. And Threshold is basically linked to Drive, so that's already ok. Although using a very different drive level might cause big issues if the ratios for bands are different. Grrrr... :(

Advance, should be like the Simple or Basic, adding some control to allow some fine adjustments.[/quote]
In my current version (will post it in a moment) Advanced mode adds burst protection and frequency/slope settings.

BETA060:
Stand alone: http://www.stereotool.com/download/ster ... 04-060.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 04-060.exe
VST: http://www.stereotool.com/download/vst_ ... 04-060.dll

DONE:
- Extra LPF before MB, stereo and AGC. Never below 16 kHz, set 0.25 kHz above actual LPF freq to avoid too steep filtering.
- Multiband compressor: Make frequencies non-editable (view only) in all but Bands section
- Started with: Multiband compressor: Differentiate between Basic/Advanced/Extreme... modes

TODO:
- Crash reported by Christian Steifen: If you change to a different category and quickly change something it crashes (VST version). Unable to reproduce, waiting for feedback - was this with BETA054?
- Multiband compressor: Differentiate between Basic/Advanced/Extreme... modes
- Singleband Compressor: Differentiate between Basic/Advanced/Extreme... modes
- Compressors: Density slider, to be used instead of Drive in simple mode.
- Compressors: Replace 'Speedup' by 2 sliders: Aggression and Softness.
- Update "main" processing window
- Update/Order presets
- Change version number
- Release

Ok, here's an idea.

Since changing the Drive can cause big changes in the sound if bands are configured differently (different ratios's, feedback vs feed forward), it's probably not a good idea to put the Drive in the simple interface - in some cases you can really break things with it.

But: I can make a new slider, let's call it 'Density', with which you can increase or decrease the drive. If you do that, the 'band mix' values would be adjusted as follows:
Say, a band has a ratio 3:1, and works in feed forward mode. Then, if I increase the 'Density' by 6 dB, the band mix of this band would need to be reduced by 2 dB.

For feedback things are a bit more difficult but I guess I should be able to come up with something usable.

This change also means that I can remove the 'Output level' slider from the simple interface, which would be great (I really don't like that one).


Also, PhantomFM just mentioned that it's probably a good idea to leave the attack times alone when changing the Speed slider, and that seems to make sense - I'll change that. In fact, I should probably also place a separate attack speed in the simple interface to allow making the sound 'softer'.

Hmm... I'm not specialist, but I can prepare some signals which can't to be correct measure without oversampling ;) So if I can, music also can :)

What I say is to simplify all in one setting, you just have to find the proportions of each to be consistent. As a user, in Basic mode, just move a slider but internally would adjust several parameters at once (in a predetermined relationship).
I think a little is what you are proposing to "Density" control. ;)

Updated some presets, no further changes.
Please update my preset GAP_Impact to version 0.92. (this version 0.4). Thanks ;)
@Hans, you can update it in next release?

Feed forward is working, and this is indeed very handy. Now I need to think of a way to do the same thing for feedback.

Ok, thanks (sorry for not checking the values :roll:)
