I need to average the n-th octave spectra (3rd or 12th) from several (2 to 😎 microphones to get a spatial average of the spectrum in the room. Is there a function in Labview that does this or something in the S&V toolkit? Thanks!
I don't think that there is an out-of-the-box solution for your task but if I understandd you correctly the only thing you will have to do is to average the power associated with each 1/n octave band of all your microphones. In the S&V toolkit the band power is an output parameter of e. g. the SVT Third-octave Analysis.vi. The band powers for each channel are stored within arrays so you will simply have to average the corresponding array elements from each of your channels.
