Hey all!
I see this thread started quite sone time ago but here is my favourite.
MAAT Digital DRMeterMK2 is fantastic. You can calibrate it yourself, there are presets in there already to satisfy almost all needs. It doesn't have stereo filed graph, phase and all those things like IK or Ozone but this one does the job every time. You can get it's companipn for free for testing Mid/Side, phase issues etc. Ah yes, it costs me literally 0% CPU. Not 0 but so neglectable, 0,1% and I can live with that. I know some here will disagree with this but I don't care. It is my opinion and I stay by it.
I vote for MAAT's DRMeterMK2. Take also it's companion and you're good to go having something of accuracy at the end. And on tracks, of course.
PS: Dorrough is fine, don't get me wrong as well as IK or Ozone. Maybe it's a preference thing, I don't know. Klanghelm's VUMT Deluxe is fantastic as well, balistics adjustable, settings of all sorts...
Da***n, there ARE a lot of grat products out there. It is probably a subjectivity in action.
Best to all Slutz out there!
