1/3rd octave band measurements with FX100 Analyzer

Octave and one-third octave band representations of measurements are widely used for real-time acoustic spectral analysis (RTA) in sound level meters. Audio Analyzers, on the other hand, typically represent spectrums with high-resolution FFT's. NTi Audio provides a tool to derive octave and one-third octave band results from FFT measurement results using the FX100 Audio analyzer. The octave and one-third octave results derived by the FX100 would be applied, for example to: Sound pressure level...
