by Pat Brown An alternative title for this blog could be “How a Balloon Pop Can Save the Day” for a sound system designer. When building room models for acoustics simulation, the order of workflow is important. The intuitive order is 1. Build wireframe 2. Assign absorption (ABS) 3. Calculate reverb time (RT) Logical, but it can lead […]
Take a step back in time to 1958. Don & Carolyn Davis (SynAudCon founders), William H. Bell and George Petry were selected to exhibit their HiFi system at Brussels World’s Fair. For 10 days, they staged demonstrations every 30 minutes drawing crowds which probably totaled 50,000. What a neat article.
I don’t see movies in theaters often, but when I do, I want a good seat. This means getting there 30 minutes early to get a seat along the center line of the theater, usually about half-way back. This provides the best stereo image and mix of the surround channels. Last week we were in […]
It’s been about 5 years since I published a couple of articles on the differences between Digital Signal Processors (DSP). You can find those articles on the SynAudCon website. I had to revisit the topic on a recent loudspeaker measurement project. The back story is that a loudspeaker manufacturer sent me a two-way loudspeaker for testing, along […]
It’s been over 100 years since Wallace Clement Sabine sculpted his famous reverberation formula for estimating the room reverberation time from a handful of variables that include the room volume, surface area, and the “alpha” of the material covering each surface area – the so-called absorption coefficient. Multiplying the alpha by the surface area yields […]
The freeware GratisVolver™ continues to be one of the most useful applications that I own. The ability to convolve impulse responses with anechoic program material let’s me sit at the mic position and listen to what a room measurement sounds like in the comfort of my office. It is also a powerful tool for producing […]
Things are buzzing at SynAudCon this week, and it’s not a ground loop. Preparations are under way for two upcoming specialty seminars – SynAudCon Digital and Making Wireless Work. SynAudCon Digital – Better Than Ever Steve Macatee and Brad Benn flew in on Monday for a couple of days of prep. We devoted the first […]
SynAudCon’s Training in Singapore received a nice write-up in Systems Integration Asia. Check out page 24.
