Adobe Audition: Spectral Pan and Spectral Phase Display

I recently discovered an awesome but misknown feature in Adobe Audition. It is the Spectral Pan and the Spectral Phase display. I rarely work with stereo data, but I am a big fan of microphone array processing and I wasn't aware all the power hidden in this software!

These view not only let you work with the frequency magnitude, but also the phase which is awesome! In the X axis we still have the time but in the Y axis we have either the difference of phase (for the phase display) or location in the stereo field (for the pan display). The frequencies are shown with different hue/colors (as opposite to the rainbow with the default setting, the blue represent the low frequencies while the red represent the high frequencies). Finally the brightness reveal the amplitude.

As example the previous image show moderatly high frequency in color yellow going from one side to another of the stereo field. The blue shows low frequencies noises that are more spread in space, but a bit more on the right, then changes side as well a few time.

Each lines represent a different frequency. In the previous image, there are multiple lines due to higher FFT size used. It is rarely requiered to use over 1024 as FFT size as not only it will significantly increase processing time, but will reduce time resolution. A high FFT size would be recommended only if you need to track the pan or phase of two very close frequency.

I have created a small tutorial on bellow if you are interested to learn more on this t0pic.

I hope that enjoy it and you are welcome to share your inputs!
