The Soundscape of a Large Family

I grew up in a large family, and with a large family, you tend to do everything big—larger than life. Dinners, camping trips, birthday parties, pets, you name it, we did it, and it always came with an expected level of cacophony. You could always tell who wasn’t home yet by the level of sound emanating from our house. And of course, this level of activity always attracted friends. It wasn’t uncommon to have double-digit numbers of people at our house for dinner on any given night—no matter if there was school the next day or not. One clear memory I have from childhood is if one of us kids…

Are Gestural Controls the Future of AV Control?

Gestural controls are getting a fair amount of coverage in the press lately, and with good reason. Devices like Myo and Leap Motion have had very high pre-order sales numbers for essentially unproven technology. That says a lot about the public’s interest in gesture-based control. Or is it the latest technology fad? What problem are they trying to solve? I’ve used a Kinect pretty extensively, with varying degrees of success (I will one day defeat you, Wipeout 3), and I’m getting pretty good at waving my hand like a maniac to turn the motion sensor lights on at work. So this week I purchased a Leap Motion and spent quite…

5 Ways to Correct Bad Mix-Minus

When I started my career in the audio industry, believe it or not we used analog electronics to implement mix-minus systems.  We painstakingly mixed phase-inverted microphone signals into the overall mix (thus the ‘minus’) at different ratios, delicately tweaking potentiometers for hours to get larger systems sounding just right.  It was a labor of love, and I remember being so satisfied when we got the perfect, natural sound we were looking for. In today’s world of digital signal processing, the ‘minus’ has been removed and in general we strategically ‘mix’ microphone inputs to outputs at different cross-point levels to give each microphone the right level at each speaker.  Unfortunately, the…

Ceiling Mic Best Practices Tip #1: Consider Room Acoustics

Ever since we rolled out our CM1-6W and CM1-6WS ceiling mics, we’ve been working to give you more information about them. This post is the first in a series of five with tips on how to use your Biamp mics to best effect in any given space. The Impact of Room Acoustics Acoustically treating a room can exponentially increase the performance and intelligibility of the audio. Concrete floors, glass walls, and high ceilings do not make for an ideal environment for ceiling mics. These surfaces reflect instead of absorb audio, and therefore cause reverberation, which reduces intelligibility and makes it difficult to understand meeting participants. By using acoustical modeling software,…
