Is Roon’s built in parametric EQ Linear Phase, Minimum Phase, or Intermediate Phase?
I’d like to know as well.
Roon’s own documentation (https://help.roonlabs.com/portal/en/kb/articles/dsp-engine-headroom-management#Because_of_inter-sample_overs) says (emphasis added for clarity):
Because of the phase shift associated with minimum phase processing, it’s possible for DSP that doesn’t make things louder to nonetheless cause individual samples to clip. Roon’s equalizer features are all minimum phase, and its sample rate converters can be configured to be minimum phase. Convolution filters may be minimum phase depending on how they were constructed.
