Thursday, May 24, 2012In The Studio: Phase—Timing Difference or Polarity?
Randy Coppinger 05/24/12 10:54 AM,This article is provided by the Pro Audio Files. What Do We Mean? One of the most confusing topics in audio is phase. I think part of what makes it confusing is that people use it in reference to more than one issue. What always seems to make things clear for me: figure out precisely which aspect is the concern then focus on the part that matters. It is such an issue that I avoid using the word phase… View this post

Tuesday, May 15, 2012Accuracy vs. Realism: Simulating The “Human” Side Of Audio Measurement
Pat Brown 05/15/12 10:27 AM,The human auditory system is equipped with two inputs - left and right ears. This “binaural” processing system provides us with the ability to localize where sound is coming from, something that a one-eared listener would have difficulty in doing. Playback systems may utilize any number of channels to surround the listener with sound, but two channels is always enough to simulate the human listener. Recording enthusiasts have long discovered the benefits of stereo microphones. While not necessarily “human-like,” they… View this post

Tuesday, May 08, 2012Understanding Sound System, Loudspeaker & Room Interactions
Sam Berkow 05/08/12 05:35 PM,If one could listen to only the direct sound of a loudspeaker, the world would be a very different place! Unfortunately, free field listening, where you have no reflections, room modes or ambient noise, is hard to achieve in everyday life, so we listen to loudspeakers in real rooms. The interaction of a loudspeaker system and a room can be very complex to understand, model or measure! One way to measure this interaction is to measure the impulse response of… View this post

Wednesday, May 02, 2012When Eyes And Ears Don’t Agree: Perspective On The Role Of Measurement
Pat Brown 05/02/12 07:02 AM,In my previous article (here), I addressed some of the caveats of measuring sound fields in enclosed spaces. The conclusion was that the eyes and ears do not always agree when it comes to sound quality. If making acoustic measurements is so difficult, why bother? Why not tune the system based solely on listening? Because there are several very good reasons for including our eyes in the system tuning process! We humans base our concept of reality upon the evidence… View this post
