Using Parametric EQ for Room Echo

[Jes2000]

Hello!

Last year, I saw a video about using the parametric EQ to reduce room echo. The guy showed how to do it manually by sweeping through the frequencies and reducing them, but then he showed a quicker way to do it by creating a certain curve. Seems like I remember it looking like the first part of a sine curve. This helped so much, and I made myself a preset to use whenever I needed. Last month, work gave me a new laptop, and I saved everything except my custom presets, of course. Worse yet, I cannot remember what that curve looked like to recreate it. I tried, but it doesn't reduce much of anything. Does happen to know what I'm talking about?? LOL If so, can you please help me? I'd appreciate it!

Firstly, you can't reduce the effect of the acoustic of a room using EQ at all - all you can do is cut back some of the frequencies at which it sounds more prominent, but in doing this you cut back the actual signal at these frequencies just as much - achieving nothing except an altered frequency response, which may be undesirable.

Secondly, what the heck is a 'sine curve' in this context? The curve of a sine wave applies to a single frequency only, and has nothing to do with anything you can do with parametric EQ. A sine curve is only a mathematical function; y = a sin (bx + c)

So no, I don't know what you are talking about. You might, though, try investigating Audition's DeReverb effect. At least this attempts to address the real problems with room tone, even though it can't cure them either.

Sine as in the shape of the curve in case it jogged anyone's memory. I don't know anything about what it does, all I know is that it worked great for me.

I think you may be referring to this video:

However, as Steve mentions, DeReverb is AMAZING and does so much more than shown in this video with one simple slider to increase intensity. Give it a go!

Hey Mike.

This video is great but not the one I was referring to. I did try the DeReverb, and it's great. Thanks!
