If you know how much I love Twin Peaks, you can probably imagine my reaction to this retweet.
From Gabriel Heinrich:
“The Virtual Sound Stage 2 design assumes that the input signal is stereo, and relatively decorrelated already, which is true for most popular sample libraries.
If your input signal is mono (Sample Modeling Brass, for example), or the left and right channel are highly correlated (this is the case with Sample Modeling woodwinds and strings, and occasionally very dry sample libraries) you will probably want to add some processing before VSS. Adding a short IR with a high wet/dry ratio and absolutely no pre-delay will usually do the trick.”
