Hello fellow madmen (and hopefully the occasional female),
I have lately been, rather intensly, watching the great Youtube videos of "Obsessive Compulsive Audiophile" (user @OCA ), a by now well-known Frankfurt genius He shows in detail how to correct for speaker/room deficiencies/influence using only the freeware REW and rePhase software.
Mastering that craft could put one in more control than when using more automated methods, I presume.
I focus on 2.0 and 2.1 systems and am struggling a bit to understand which of the presented methods that can be combined and in what order that should be. The videos I am referring to were released mainly between 2 yeras ago and up until 8 months ago.
For instance there is:
* VBA - Virtual Bass Array, create a convolution filter which reduces LF dips and peaks based on an inverted LP filter with appropriate cut-off frequency and slope, adapted to room measurements/fundamental mode frequency. Allegedly (from Youtube comments) it is hard to combine this method with other filters?
* Inversion of FR around a target curve (instead of REW's parametric EQ)
* Inversion of minimum phase response below Schröder frequency (the method which was last presented and considered superior to the other inversion method above)
* Correction of phase skews from crossover, bass reflex port and box
* Other corrections of excess phase in rePhase using allpass-filters
Generally, the rePhase actions seemed more difficult to me and more of an art. Except maybe when only (roughly) the direct sound was windowed out in REW before export to rePhase.
A video or text clarifying a kind of current best practice would be much appreciated. Of course, all help from anyone with sufficient experience in this field is very much welcome.
Thank you & a nice weekend
