All About Diffusion is the latest release in our "See and Hear" video lecture series. Most people have no way to hear what diffusors do or how they sound in a room. So this video explains diffusion in plain terms with no math, then lets you hear an acoustic guitar recorded in close proximity to five different surface types - a QRD diffusor, a poly diffusor, absorption, a bare wall, and a typical bookcase. The video is 16x9 wide-screen, and the audio is at 256 kbps for highly accurate sound.

Sorry I keep having questions pop up, but being new to the hi-fi thing, I can't help it. I always try to google/forum search first, by the way. Sometimes I don't know what terminology to use to frame the question, so that can be problematic. In any case, I appreciate everyone's advice - you've helped tremendously. Seriously. I'd be lost.

Just a head's up to SM, JA etal. - check out the comments below Fred Kaplan's excellent blog about the Sonny Rollins concert - they are all filled with SPAM. I don't know if there is a way for you to prevent this happening but until you do manage to find a way it's very annoying and quite a big turnoff, seriously devaluing the worth of both the blogs and the comments. Check it out:

SPAM filled comments

This issue is amazing. With JI taking us to the new world via by a superb music server, and on the other end, AD takes back to 78's. Mickey has us cleaning LPs in the sink!!!!! KR tells us about new Hi-rez releases that we can hope will work out better than SACD. And then, John Marks reminds us, as only he can, that this is a great time to be an audiophile, regardless of the value of the dollar.

Went to Virgin Mobile music festival in Balto.. 2 days of varied bands. From Dylan to Nine Inch Nails, Andrew Bird to Kanye West, She & Him to Armin Van Buurin. Many highlights (Black Rebel Motorcycle Club, Offspring, Chuck Berry, Sharon Jones & the Dap Kings) and lowlights (Dylan, Lil' Wayne, Jack Johnson).

I went to see Ethan Winer on Saturday in Buttfuck Connecticut. Why do all forum members (DUP and Ethan) live in the boondocks, the bowls of their respective states? Why can't you guys move closer to civilization (New York)?

It took me 2 and a half hours to get to Ethan, but the trip was well worth it. Ethan is one of the nicest people I have ever met. He's a very open, and honest guy, a gracious host and very good company.

Stephen M's favorite TV show had a great profile of Shelby Lynne this morning. No rant, just a rave for this very cool artist.
