  • Vienna Suite: convolution reverb and decorr

    Hi,
    I've been searching the manual and the forums for some clue regarding the de-correlation parameter in the convolution reverb, but to no avail. What does this parameter exactly do and when should I use it?
    Best,
    D.

  • denis,

    I had done some Net searching about decorrelation; here are some notes I retained.

    1. From VSL themselves:

    "There is no specific slider or knob for controlling early reflections. We have made the control solution for this a little bit different than other convoverbs out there. To simply lower the early reflection level, you can set the volume node lower in the beginning of your impulse. If you wish to have less defined early reflections, you can set a higher value for the decorrelation graph in its early stage. Our decorrelation algorithm basically will act the same way as a diffuse acoustic material, and the resulting sound is usually very pleasant if you have any irritating ER's you want to get rid of."

    2. various tech discussions:

    'Decorrelation: While not a classic reverb control, decorrelation allows greater control of the reverberationís stereo spaciousness. "

    "It is also possible to use only one tail instead of two, and later apply some stereophonic adjustment - decorrelation of the channels - to have a stereophonic experience, but this is not discussed here. "

    I hope this helps.  In my own limited listening tests, it seems to vary the stereo effect, if I recall right.

  • Thanks a lot Larry. Now I understand why Beat uses decorrelation to create different depth. That makes sense. Oh, by the way, where did you find this explanation by the VSL team?

    I dug up this thread:

    http://community.vsl.co.at/forums/t/21494.aspx?PageIndex=4

    See Martin's reply, 4th entry down from top.

    I keep various notes about VSL operation, and if I'm smart, I even store info about what thread they came from. -)
