Audio Spectrum Analyzers (Signal Analyzers) are expensive.
Measuring the frequency response of an audio device by the manual method is tedious and time consuming.
Setting the frequencies of a Graphic Equalizer without special equipment is a tough project at best.
In this video I am going to show you a quick and inexpensive way to accomplish all of these things using an inexpensive USB Audio Interface, some FREE software and your computer.
Here is the link to the download site for Visual Analyzer:

Here is the link to where to buy a Behringer UCA-222

Here are the promised links to the UCA-222 Driver and Instruction Manual:
DRIVER DOWNLOAD: asio4all.en.softonic.com/down...
MANUAL & LOTS OF OTHER STUFF: www.behringer.com/product.htm...
I decided to NOT provide the actual files in a ZIP file so you can be assured to the get the latest and greatest from the manufacturer themselves.
