An octave is the interval between two frequencies where one frequency is twice the rate of the other.BandwidthThe bandwidth of a filter denotes the range of frequencies the filter allows to pass through. Calculating the bandedge frequencies informs you of the bandwidth's characteristics.Settling TimeWhen starting or resetting the filtering operation of fractional-octave filters, a settling time is required before the measurements are valid.Filter BanksOctave filter resolution is limited because only 11 octaves exist in the 16 Hz–16 KHz range. To overcome the limited resolution of octave filters, you can use other filters known as fractional-octave filters.Parent topic: Fractional-Octave Analysis
