What does You think, does it acceptable to use it for DRC?

I'm not a expert in DRC, but I think if DRC algorithms use parameters like attack and dekay is for good reasons.

A instant volume conversión with simple math formulas produce distort output like you can see in this image.

With a frequency analysis you can see the audible overtones, not present using more sophisticated algorithms:
Frequency Analysis.

For me the DRC is only useful with ac3 or dts sources, and this work ok with your modified NicAaudio.dll. For others uses the compand Sox function still work better than this AudioLimiters.
