This program is an audio analyzer with FFT and n-th octave frequency analyzers and oscilloscope.
The octave analyzer can show the frequency spectrum at 12th, 6th, 3rd and full octave resolution. (A standard license supports all resolutions)

With the FFT frequency analyzer you can see the spectrum on a linear scale, which can be useful for harmonics and other analysis tasks. Also on board is a real time oscilloscope which is always useful when analyzing audio signals.

There are three main analysis modes you can use. The octave band RTA is the classic analyzer with a logarithmic X-axis:

 The resolution is set to 12th octave, with fast time averaging. The input signal in this case is a pink noise signal band passed at 1kHz, generated with my Filtered Noise Generator. The resolution can also be set to wider bands.
