At first glance, RTA octave band measurements appear rather coarse compared to an FFT. However, it is precisely this reduced resolution that proves advantageous in many practical applications.
The key point is that octave bands are based on the frequency-dependent resolution of human hearing and also comply with standard technical specifications. As a result, they provide a more interpretable and practical representation than a high-resolution FFT. Our x1RTA and x1BAR products are excellent software solutions.
