Foreword by Bob McCarthy

Foreword by Bob McCarthy

I have written and released a book about sound system design and optimization, inspired by these blog posts, and fittingly titled Between the Lines: Concepts in Sound System Design and Alignment. You can purchase a copy directly from the publisher by clicking here, or order it from most booksellers. I am incredibly humbled and honored that the …

Higher Ground: The Subtle Art of Giving A Shit

Higher Ground: The Subtle Art of Giving A Shit

In a recent post on this blog, I discussed what I refer to as The Magnitude Fallacy, which describes the human tendency to focus disproportionately on All The Small Things. In the weeks since, I’ve come to realize that this concept also readily describes my views on the general state of sound system engineering. Lately, …

Deriving 6o6’s Lateral Aspect Ratio

Deriving 6o6’s Lateral Aspect Ratio

Those studying the third edition of Bob “6o6” McCarthy’s system design treatise, Sound Systems: Design and Optimization, are introduced to a mechanism coined the Lateral Aspect Ratio. The basic idea is as follows: The coverage angle of a loudspeaker is traditionally defined as the point as which, moving axially away from the on-axis reference, the high …

The Magnitude Fallacy

The Magnitude Fallacy

Humans are worriers. It’s what we do. Some more than others, of course – my late Italian grandmother could have won an Olympic gold medal in it – but there are legitimate scientific underpinnings to this. Statistically speaking, humans are not good at estimating probabilities or risk. In his book Innumeracy, author John Allen Paulos …

Microphone positions for system alignment

Microphone positions for system alignment

“Where do I put the mic?” is probably the single most frequently asked question whenever system alignment topics are discussed. Ask fifteen sound engineers and you’ll get twenty opinions – here we will instead explore a reductionist approach to the question. A measurement microphone can be considered a test probe – its job is to …

20-Minute System Tuning

20-Minute System Tuning

Note: this is an updated and expanded version of a much older post. It also appears in this same form on ProSoundWeb. There’s a running joke in the system optimization community: “How much time does it take to tune a sound system?” The answer (“as much time as you have”) is often all too true …

Impulse Response vs Transfer Function

Impulse Response vs Transfer Function

Q: Wondering if I could get a hand with using Impulse Response to tune PA as opposed to using TF with Pink Noise. I’m aware of the “Common way” blasting Pink noise, Finding the delay and then storing traces and averaging and making the adjustments. I’m just not familiar with using Impulse Responses. Is there …

Conceptual Explanation of FIR Filters

Conceptual Explanation of FIR Filters

As technology marches on, FIR (Finite Impulse Response) loudspeaker presets are becoming increasingly common, and with good reason – they’re not just a marketing buzzword. FIR filters offer some real benefits in pro audio applications – and, like other tool – they come with their own drawbacks and considerations. I am often asked how FIR …
