during last SDCompo Round I stumbled upon the question what kind of algorithm Renoise’s DC offset removal mechanism actually uses (either the DSP Version or those built in implictly in MST).
Does it use a bias correction approach / symmetry correction or is it a highpass filter in disguise, or is it both ?
See also http://en.wikipedia.org/wiki/DC_offset
I ask because I usually don’t use the DC Offset removal in MST. I use a butterworth highpass and IMO it does a great job
Now I want to find out which pros/cons the additional usage of the DC Offset removal has, and maybe if a combination of dc offset removal and highpass makes sense.
