Valhalla Room aliasing artifacts 2012-09-12T07:37:54+00:00 First of all, I don't want to offend anybody. Please don't get me wrong, Valhalla Room is a very good reverb, one of the most musical reverbs I ever heard and definitely has the best value for price. Moreover, I even bought it and am very glad. But there are some things I don't like very much. I just want to share my observations. Also my thoughts and observations can be totally wrong. The Room has very pleasant character of modulations, which can be almost unaudible, but have an effect of pleasant blurring the signal. But there are some spectral artifacts in the sound (especially in dark modes) that are not so pleasant. I tryed to take in that I hear and did a 20Hz->20kHz sweep test. And yes, there is aliasing in the spectrum. The LV-426 mode(my favorite mode due to dense tail and pleasant modulations character. I think I would like bright clean variant of LV-426 with its modulation and density but with full sample rate and high quality interpolation. May be I'm wrong): https://dl.dropbox.com/u/57065234/vroom/vr_lv-426_small.png full-size: https://dl.dropbox.com/u/57065234/vroom/vr_lv-426.png Yes, I know, the dark modes operate on low sample rate like vintage reverb units. But may be there was brickwall filter in the sound input of those reverbs to cut frequencies higher Nyquist? The fully-sample-rated Bright Room mode has a little aliasing too (may be interpolation artifacts mirrored by Nyquist?) https://dl.dropbox.com/u/57065234/vroom/vr_bright_room_small.png full-size: https://dl.dropbox.com/u/57065234/vroom/vr_bright_room.png Compare to Logic PlatinumVerb (but short tail. I know I had to make it longer for comparison): https://dl.dropbox.com/u/57065234/vroom/platinumverb_small.png full-size: https://dl.dropbox.com/u/57065234/vroom/platinumverb.png But I may be wrong, and may be Valhalla Room would lost its magic without aliasing artifacts. trance_lucent https://www.kvraudio.com/forum/memberlist.php?mode=viewprofile&u=82512

Keep up the good work Sean.

The Windows updates will be AAX ports as well. The AAX user base on Windows has gotta be WAY smaller than on OSX (about a 4:1 ratio of OSX versus Windows PT users last I checked), but I still need to make all the framework changes on Windows, to be able to maintain a cross-platform code base.

This will also allow me to update in the future when various issues are fixed in the Juce code. The AAX ports require me to use the latest and greatest Juce code base, and this is where bugs are fixed.

And yeah, "effing AAX" ports is the mild way of putting things.

Still, I see a light at the end of the tunnel.
