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 …

Since then, the program has grown tremendously, so much so that Chris put together some snazzy artwork and our friend Sam made us a great Google Form that interested parties can fill out …

System Processing and Control for Live and Touring: The Way Forward

System Processing and Control for Live and Touring: The Way Forward

I’ll be honest, I’m pretty jaded when it comes to DSPs (a technically-not-super-accurate blanket term that we often use as a catch-all for system processors, matrix mixers, and the like). FOH control racks in the live / touring world continue to be dominated by the venerable Lake with some Meyer Galileo thrown in for good …

Why I Started the Signal To Noise Podcast

Why I Started the Signal To Noise Podcast

I was recently approached by an individual who runs an audio engineering website, and was offered a cross-promotion arrangement: I share a few of their links to my “audience” a few times a month, and they will share mine. We can both grow our audiences. I said no. Besides the fact that I don’t have …
