Perform real-time spectral analysis on up to 16 input and output channels of a single audio device with a single FFT Analyzer. Or, better yet, analyze signals with an FFT Analyzer assigned to each of multiple audio devices.
Plot the spectrum with a linear, logarithmic, or dB amplitude scale and a linear or logarithmic frequency scale.
Use the dual cursors to precisely measure signal strengths (peak, rms, or peak-to-peak) at any frequency, or measure the difference in signal levels between two frequencies.
Harmonic cursors also facilitate harmonic distortion measurements (THD, THD+N).
Adjust amplitude scaling independently for all input signals.
The FFT Analyzer supports a large number of FFT lengths, including lengths that result in integer frequency resolution for popular audio sample rates.
