Make It A Double: Inside Approaches to Parallel Processing

Make It A Double: Inside Approaches to Parallel Processing

One of the earliest studio mixing tricks that I learned was parallel processing – running the same signal through several mixer channels and processing them independently. There are a few variants of this technique, the most common being parallel compression. For example, the first application I saw of this was when a studio engineer double-patched …

Why Your RTA App Isn’t Showing What You Think It Is

Why Your RTA App Isn’t Showing What You Think It Is

I was recently reading a forum discussion about whether an external mic was necessary when using a mobile app for RTA / spectrum analysis.  It had occurred to me that the physical dimensions of the device might cause some significant spectral variance as the device’s orientation changed relative to the source. In other words, the …

Filters, Phase, and the Double Patched Kick

Filters, Phase, and the Double Patched Kick

This post comes on the heels of this article by my friend Jim Yakabuski, and my recent article about double-patched channels, so if you’re not up to speed on those, check them out and then come back. I’ll be here.   Back? Okay great. So the discussion now is that we want to split a …

How Not To Set Up A Crossover

How Not To Set Up A Crossover

This week I am working with a modern black-box theater to configure and optimize their installed system. I haven’t gotten to any of the “fun” stuff yet because we’re still untangling the mess left by the original installers. Allow me to elaborate on that statement: Usually when a subwoofer is not working, someone’s blown up …

What System Optimization Means To Me

What System Optimization Means To Me

A colleague of mine owns a production company and had a gig yesterday for a government accounting agency. The setup is simple: a podium mic and a couple of RF handhelds that everybody needs to be able to hear and understand. The trick is that the event is inside a literal aircraft hangar, probably the most acoustically …

Shine On, You Crazy Diamond

Shine On, You Crazy Diamond

A colleague’s upcoming gig posed an interesting set of constraints for the subwoofer subsystem design. It’s a diamond-shaped stage and due to the nature of the event, all the boxes must be located against the stage, not spaced out in a more typical broadside or L/R configuration. (Seeing as there’s a drape/video line about midstage, …

Beware Autopilot and Flying Wrenches: Why I Am Uncomfortable with Getting Too Comfortable

Beware Autopilot and Flying Wrenches: Why I Am Uncomfortable with Getting Too Comfortable

“It’s an easy gig. Just three microphones.” Sounds good, right? But as the day went on, things began to change. The event was a “roundtable” discussion between a moderator and two CEOs who each had a net worth in excess of a billion dollars. They have “people.” There was a fair amount of “hovering” going …

The Dance Foldback Conundrum

The Dance Foldback Conundrum

A few times a year, I run audio for college dance performances. It’s a weird gig from an audio perspective, as it’s a single input show (Qlab from a solid state hard drive because after an embarrassing mishap years ago, I will never again trust a CD for live playback). Cue calling falls to the …
