Hi there,valhallasound wrote: The idea behind the Dark Modes (Dark Room, Dark Chamber, Dark Space, Nostromo, Narcissus, LV-426) is that the reverb is downsampled, so there won't be any signal above 1/4 the sampling rate. The downsampling filter (8th order elliptical, less ripple) used isn't super steep, so the rolloff will probably start happening around 8 kHz for a sampling rate of 48 KHz. Any signal/artifacts above 1/4 the sampling rate should be attenuated by 106 dB, as that is the highest sidelobe for the elliptical downsampling filter.
I also use Valhalla room for my stuff, since I got it. I really love it! Thank you so much for this reverb! Besides I would like to ask a question, which hopefully is tolerated here - even if it's a little bit offtopic:
You already explained the technical idea behind the dark modes. May I ask what the practical idea is? Is it for less CPU usage or something like this in the first place? Or is it only for a different sound? I have to confess that I was sitting many hours switching between the "Large Chamber" and the "Dark Chamber"(filmmusic orchestra context). Somehow I like both, since the Large sounds bit brighter of course, but the Dark sounds a bit more "something is really inside the room". In the end I was wondering, if there is maybe some very basic difference in the usage of these two modes?
Thanks for the reply!

Edit:
May I add some further question? Your "tutorials" are nice on your site. Nevertheless: you did not mention how to find the right algorithm for the right situation. Of course there are some information about how the algorithms work and so on, but I still do not feel very comfortable with all the algorithm choices. Is there maybe some basic rule or trick how to chose the right one?
Please forgive me for this offtopic. Maybe I should start a new thread in the Valhalla DSP foorum?
