The convolver processes small impulse files ( cabinet etc…) almost identical to most other imp.reverbs .
However sometimes when loading certain imp.files , there is still a big difference …especially medium sized rooms etc…
It’s mostly the first portion of the reverberated output that makes the difference , ( obvious when rendering a 1 sample impulse trough convolver and comparing the rendered file )
When other reverbs sounds distant, behind you; convolver sometimes sounds nearby/centered , ( so obvious when using headphones)
I noticed that convolver is applying dc offset filtering ,which might clarify the different results compared to other reverbs .
As a test I created an impulse file of the psp pianoverb vst effect .( process the dsp effect with a 1 sample impulse )
The rendered file ( see screenshot ) has no negative energy .
When this file is loaded in the convolver , the convolver is applying dc offset filtering .
Took it a step further and loaded a sample with only +1 energy , a pure dc sample .
As expected ,convolver applies high pass filtering.
I don’t know whether the filtering is done to the input signal or the imp.file , or both.
The effect is most noticeable when processing a oneshot decaying rampwave ,positive only , convolver loaded with the provided imp.file .
I can totally understand the benefits of this , minimizing the risk of dc offset .
On the other hand , this might also modify the processed output .
Maybe a option to turn off dc filtering …?

Don’t get me wrong , the convolver has definately improved since it’s first appearance , but it still has some difficulties
with the beginning of certain imp.files …
