Slap not the same live.

We have house sound issues but they are being resolved somewhat.

We have on of those devices that sweeps the room for frequencies and attenuates them, I think it's a feedback eliminator, and supposedly you can save the scene where you don't have to do it every time, but I'm a little skeptical of the over all effectiveness of it. I played in bands for years that fought off such difficulties with just minor tweaks to the eq.

There's no perfect room, or even outdoor hollow stages... and some rooms are horrendous for sound, bass in particular.

The best sound I've ever gotten was outside set up on the ground. Just some mats under us.

Those ‘attenuators’ may work like a computer’s firewall or spam filter and just attack anything it defines as unfriendly.

You can't really save a preset for a feedback eliminator to be used at the next gig if the gear is not left in place.

Some modes of feedback are dependent on room resonances and microphone characteristics. A preset has a good chance of catching these. Other modes of feedback are based on the distance between the mics and speakers. Unless everything is in exactly the same position, the presets for these modes of feedback will become invalid.

I used to ring my PA for feedback at every gig. I noticed there were a few frequencies that I always dipped, but most of the corrections varied significantly from gig to gig.

If the temperature in the room changes significantly, you may have to ring the room a second time because it can shift resonances up or down.

It's like a sonic maximizer that's supposed to set the sound just right for the room... they save it for each place we play, but I've mentioned to them that there are too many variables, but they think it works, just like a placebo effect.

Each time we go back in there, we don't get the speakers exactly the same, mics aren't exactly where they were.

I've seen them use it it in a room with draped walls that are closes while we are getting a sound check... sound check ends and the walls open... totally different room. But what do I know?
