  • the easiest way to eliminate feedback is to use your own ears, when mixing sound there is only one tool u can trust, your own ear, if something sounds a bit off then chances are it probably is. to eliminate feedback look at speaker position and where a speaker is pointed, think of a speaker like a light if your "light" shines on your microphone the chances of feedback are greatly enhanced. if u need a rundown and some tips, send me a message ive done sound designs for londons west end.

  • Why not make the artists all wear false teeth on stage,,,:thu:

  • So what software is the best for ringing out a room.

    I know most people are saying just use your ears, but if there is a tool to make things easier, I am all for it. Every room is different, so running this type of software on a laptop could be a real time saver.

  • @samuelr720 All you need is a 31 band EQ and your ears. Turn up the mic gain until you get feedback and try cutting different frequencies until the feedback goes away.

  • @samuelr720 take each frequency band that are close to the frequency you think it is and try each one

  • thnx for the vids, what spectrum anaalyzer software do you use?

  • How do you get a hold of a spectrograph?

  • @bikergeekgd I agree. I'm pretty sure that guy shouldn't even be messing with this stuff. 31 would be the appropriate number.

  • Very good clip - concise and to the point!

  • Using this technology can prevent ear damage. Feedback is very bad for your ears. Mixing a band can only be done by ear. If Its there, (ab)use it.
