- You're looking at some results as captured and dispalyed by ARTA .

- Author of this software is : Ivo Mateljan , Electroacoustic Laboratory, Faculty of Electrical Engineering, 21000 Split, Croatia.

- Download his shareware Here !

- I use an M-Audio USB card. This is it ( it has more input channels than necessary / most people should look at the Fast Track Pro instead ) >

- My test mic is this Audix TR40. >

- Sorry , but I don't have that file saved ( so, I have no ability to reprocess without retesting ) .

- I agree that these semi 3D perspective makes it quite hard to precisely connect a frequency to "some big bulge in the color" .

- It's easier to make the connection using the "sonogram" layout which is 2D ( and makes no bones about it ) .
