California Soundscapes with Dan Dugan

Thursday, October 20

Join us for a visual and auditory tour of sixteen fascinating California soundscapes in surround sound. Dan Dugan, a technical mentor for the Nature Sounds Society, will introduce you to the theory of soundscape analysis, demonstrate the difference between mono, stereo, and surround sound, and share a brief survey of the available equipment. Learn how our national parks are struggling with soundscape preservation, and how natural sounds are documented by nature sound recordists in two styles — species hunting and soundscape recording.

Dan Dugan, inventor of the automatic microphone mixer, has recorded surround sound in national parks including Muir Woods, Joshua Tree, and Yosemite. His recordings are submitted to the parks for scientific research.

Date:   Thursday, October 20

Time:   6:30 p.m. refreshments, 7 p.m. speaker

Place:  Northbrae Community Church, 941 The Alameda
