Church Sound: Working Within Volume Limits

Live Within Your Means
Or in this case, your leadership. In my current church, I have a different definition of “too loud” than my senior pastor does. Since his is lower, I have to adapt my mixing style to suit him—he’s the boss after all. The challenge for me is that his definition changes week to week.

I’ve been told it’s “awesome” one week at 92-94 while it could be “too loud” at 90-91 next week. So I’ve spent a lot of time working on getting my mixes right, the balance correct and the system tuned to his liking.

I’ve also adapted a different way of metering my loudness. I use a software program called LAMA, which can display both a standard SPL readout (I use A, Slow) and an average (I have chosen 10-seconds). LAMA allows me to set colors at various levels so I have my average number turn yellow at 85 dBA SPL, and red at 91, which gives me a “corner of the eye” indication as to where I am.

I keep an eye on the standard readout as well, and occasionally my peaks run into the low to mid 90s, but for the last month and a half, if I keep my 10-second average below 90, my pastor is happy.

Personally, I’d be happier if it was louder. But I’m not paid to be happy; I’m paid to make him happy. I often say, “If you can’t abide by the limitations your leadership puts on you, then you need to leave.” Same applies here.

Again, I would talk to my pastor and find out where this is coming from. As him if it would be OK to try mixing to a 85 dB 10-second average and see how that feels. Address the spectral and mix balance issues; you might be surprised.

Beware Compression
The reader asked if he should compress the inputs, and bus compress the mix to give him the power he wants, while staying under the “legal limit.” To me, that’s a little like putting your phone on speaker and holding it in front of you while you drive.

Yes, you could compress the inputs a few dB, then bus compress a few more, then compress the master another a little further, and compress it again in the DSP. That would certainly raise your average SPL while keeping your peak below 85.

However, it’s very likely that this technique will result in the perception that it’s even louder, which may cause your limit to be lowered further. You could also hard-limit your DSP so you can’t exceed 85; but again, if you suck all the dynamics out of the music, all the life goes with it, and it will also sound louder. This would be self-defeating on two fronts.

At the end of the day, I think you’re better off dealing with the root cause of the problem rather than trying to figure out how to stay below an arbitrary number.
