Toning Your Sound System

No this is NOT a typo. I did not mean to write “Tuning your sound system” because that is entirely a different subject. So what is the difference between toning and tuning?  Here is a simple example from the muscial side: This is my son Simon. He has a guitar effects pedal that has exactly […]

SIM3 Optimization & Design Seminar at UC Irvine

We just completed a 4-day SIM3 training seminar in the south side of southern California. UC Irvine is located very near the ocean, which makes one wonder how folks could study when the surf’s up. It is also right next to John Wayne Airport. Naturally I flew in and out of LAX, and drove the hour down to the other […]

Subwoofer Delay Taper (Update 1)

Here is a quick preview of my next post.  These plots contain concentric circles. Each represents a wavelength traveled from the speaker at 125 Hz (2.73 meters). The first one shows 7 speakers spaced at 1/2 wavelength (1.37m) and all set to 0 ms delay. The concentric are all the same for the 7 speakers […]

Line Array Gain Taper (Breaking the Line II)

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? […]

Sound Systems: Design & Optimization – 2nd Edition

The second edition came off the press in October of this year and I am quite happy with the result. First thing is that the book can sit on your lap or a table without flopping around. The graphics came out much better. I was able to get them reformatted so as to get the most […]
