Learn all about Filters from synthesist Marc Doty and support the educational activities of the Bob Moog Foundation all at the same time...
If Oscillators generate sound, then do Filters degenerate sound? Find out in this third course in the 6-part series on the Foundation of Synthesis that is all about Filters and Subtractive Synthesis. Bob Moog Foundation lead educator, Marc Doty, introduces you to the basic concepts of sound filtration. You’ll learn about cut-off frequencies, resonance and see every resulting waveform displayed on an Oscilloscope.
Filters are some of the most important devices in the synthesists tool box. They give sounds their unique characteristics. They allow the synthesist to sculpt the sound to reveal the hidden sonic qualities deep inside. Learn all about the different kinds of filters and how they are actualized by the designers of great hardware synths. Learn how these filter designs are, in many respects, what makes one synthesizer sound uniquely different from another!
Throughout this series Marc demonstrates the science of sound with informative animations and hands-on demonstrations of his collection of classic synths from many different designers! It’s great to see how these fantastic instruments deploy their sonic technologies.
Bob Moog was an early pioneer and inventor of voltage controlled analog synthesizers. He revolutionized the music industry and his ideas, inventions and musical instruments have dominated the sound of music for more than 30 years. Aside from being an innovator, Dr. Bob was an outspoken advocate of education. The Bob Moog Foundation, created by his daughter, Michelle Moog-Kousa, continues his legacy with Dr. Bob's SoundSchool, the preservation of his inventions and the development of the Moogseum – the only museum of its kind dedicated to the advancement of sonic education. We hope you will help support the BMF's efforts by watching these courses with the knowledge that a large portion of the proceeds go to support their awesome efforts!

In windows 8, I muted system sounds in the volume bar. But the UAC popup still makes a sound. I'm running a regular account, the UAC popup asks for the password. I have tried many ways on google and they all did not fix my problem.
