 == NVGate 1/n octave plug in==
-This plug-in computes 1/1, 1/3, 1/12 and 1/24 octave analysis based on order 3 digital filters and RMS detectors.
-The filter bank complies with:
-'''IEC 1260 class 1''' and'''ANSI S1.11-1986'''
-Mid band frequencies are based on powers of ten.
 '''Available results''':
-'''FilterNumber = ((1/Mode) * (ln (High/Low) / ln 2)) <nowiki>+</nowiki> 1'''
-Where:
-"Mode" is the value of the ''1/n octave/CPB filters/Mode ''setting: 1 for octave, 1/3 for 1/3 octave…
-"High" and "Low" are respectively the values of the ''1/n octave/CPB filters/Upper central freq'' and ''1/n octave/CPB filters/Lower central freq'' settings
-For example if mode = 1/3 octave, High =7.94 kHz and Low = 7.94 Hz then ''FilterNumber = 3 * (ln 1000 / ln 2) <nowiki>+</nowiki>1 = 30.897'' =<nowiki>></nowiki> 31 filters
