Off to Mexico for AES and SIM3 Training – Updated

I have been busy putting together new material for SIM 3 training, and AES seminar and the upcoming Broadway Sound Master Class. You have seen some of the work in progress below, but I have had to push to get things ready for showtime.  Sorry for the delay in getting more things posted and for […]

A Concise Article on Cardioid Subwoofer Arrays – by Steve Bush

This article  Tech Talk: Building Directional Subwoofer Arrays Working toward consistency. was posted just today on the ProSoundWeb by Steve Bush. Well written, concise, plain English and NO MATH!  (lo siento que no es Espanol pero tiene fotografias). I need say no more.  Geez.  That was the easiest post I ever did! 6o6

Phase alignment of spectral crossovers

This is a continuation of the impulse response subwoofer thread. Here are some screens from Sounds Systems: Optimaztion and Design that deal with phase alignment of crossovers. The figure above shows the phase responses brought together between sub and main.  The crossover is not steep and therefore the phase response overlap over a wide range. […]

Training at Disney Animation II: Size Matters

In the world of animation the world can be as big a basketball and a basketball can be as big as the world. In the real world, size matters. Not in the animation world. In the world of animation audio, size does not seem to exist either. Low frequencies don’t have a wavelength in ProTools. Sure they […]

SIM3 Training for Disney Animation Studios

This week I spent two days at the Disney Animation Studios in Burbank California. This is the place where major animation films are created. Unless you have been living under the Rock of Gibraltar you know what these films are.  Mermaids, Beauties, Beasts, Princesses and more come to life in this space in the form […]

Phase Alignment of Subs – Why I don’t use the impulse response

OK. The saga continues down below………………………. What is the best way to phase align our subwoofers to the mains? There is a hint in the way the question was phrased. I didn’t say time align (and it is not because I am afraid of copyright police). I say phase align because that is precisely what […]

Cardioid Subwoofers

A hot topic of discussion is cardioid subwoofers, so this will be the place to get that topic going. At the moment I will use this as a test to see if I can upload a few graphics from the book here.  The first will be some pics that describe the behaviour of end-fire arrays. […]

Breaking the line

A friend of mine who is not an audio engineer went to a show and later told me it sounded too loud and was unintelligible. Sound plausible? Sure. Now try this: a friend of mine went to a show and said it sounded like the line of the speakers had been broken. Still sound plausible? […]

Line Array Tuning

I’ve opened a new page on line array tuning entitled “The ABC’s of Line Array Tuning”   you can find it in the tab at the upper right corner. Comments welcome 6o6

Interpreting Coherence on the FFT Analyzer

When we make the transition from the simplistic renderings of one-dimensional acoustical analysis, i.e: those that present amplitude only, we have several new traces to contend with. The most notable are phase and coherence. Phase is often minimally grasped and coherence even less so. These are both difficult because we don’t have simple mechanisms in […]
