  1. REW convert frequency spectrum to fractional octave

    REW Forum
    When taking a RTA measurement in REW you have the choice of taking spectrum measurements (power/hz) or various fractional octave measurements (ie 1/12 RTA). It is impossible to ever compare the graphs of the two due to the different units, though it is mathematically possible to convert at least...
  2. Fractional octave smoothing

    REW Forum
    How fractional octave (e.g. 1/12) smoothing is done in REW? Is it by a Butterworth filter or brick wall filter?
