Spectra Foo Complete is an audio measurement & metering software package made by Metric Halo. What’s up with the “foo”? It’s my understanding that Foo started out life as a japanese to english / english to japanese translation program & became an audio measuring tool.
Since I own & use Spectra Foo Complete, the screen captures you see on this website were made with SFC. It is not the most popular FFT app but it’s likely the most versatile. It was originally a Pro Tools studio measurement & metering plugin & eventually became a stand alone app. It has some tools you won’t find on any other competing app.
One note of importance. The TRANSFER FUNCTION tool comes with Spectra Foo Complete. The standard version of Spectra Foo does NOT.
