How to Estimate Delay and Level Offset Between Speakers in Your 3D Models
Save time in the field by presetting your speaker output delay and level offsets. Here's a model from a recent show where I estimated the level and delay for a pair of relay speakers and line of front-fils. If you know the difference in distance between two sources, you can accurately estimate their time offset, and therefore, the delay necessary to bring them into alignment. The challenge is finding the correct crossover point. Drawing About Sound Crossover (spatial): An … [Read more...]
Do all-pass and FIR filters cause delay?
For a long time I was afraid of all-pass and FIR filters because they seemed exotic and supposedly cause lots of delay, making them unusable for live sound. Turns out this was just an excuse I was using to avoid some mental hurdles. Do all-pass filters cause delay? Here's a measurement of my BLU-160. It's an output processor from BSS. Pretty boring. Here's that same measurement with 5ms of delay inserted. Let me draw your attention to the Live IR. It's the exact same shape as in … [Read more...]
SIM3 is easy. The hard part is figuring out what to do with that data.

In this episode of the Sound Design Live podcast, I chat with Dale West and Brian Mohr about the most important things we learned at Meyer Sound's SIM3 seminar with Bob McCarthy. We talk about calculating phase offset for a frequency range, using lateral aspect ratio to space your front fills correctly, aligning off-axis points of your speakers for even coverage, and debunking line array myths.

What is Audio Visual Integration?
Subscribe on iTunes or SoundCloud. Support Sound Design Live on Patreon. In this episode of Sound Design Live, I speak with writer, educator, and AV integrator Josh Srago. Srago has worked in recording, broadcast, television, concert sound, corporate events, and AV integration. In our interview he claims that having no specific focus was the best career choice he ever made, and walks me through the life cycle of an AV integration project. Srago also talks about the value of a CTS certification … [Read more...]
