Hello, While on the list I might as well make a feature request. Or is it already there and did I look over it? A simple form of editing sample points. At the moment I'm working on a recording that is far to low in volume. So I tought of first using the normalise function to give it a large boost. But there are a few very short sharp clicks in it that go almost all the way up. If I could just "paint over" those few samples it would speed up the process a lot. Regards, Johan |

A typical normalize function finds the maximum sample in the audio and adjusts all samples based on that one. The Adaptive Normalize (as far as I know it's not done in any other editors) (IIRC) uses a constantly changing maximum based on RMS detector. It's a little bit like a compressor, but still quite different in the details. You may have to play with the parameters a bit, but after a while you'll have something good sounding. I record some live speaking events with a room mic. The crowd-noise (desired to be in the recording) and the speaker have very different amplitudes and I use this function to balance it all out. It works pretty well. -- Davy >Regards, >Johan > > >------------------------------------------------------- >Using Tomcat but need to do more?

I have played a bit with the adaptive normalise and can very well understand your use of it in the case of spoken word. But here I have a music recording with a few loud "whacks" in it (like a hit on the mic stand). It isn't enough to use GWC for those 3 clicks. But I don't see an easy way of dealing with them with the tools as they are right now. But it nothing urgent, there are ways around like attenuating the click a few times until it is about the same level. > > A typical normalize function finds the maximum sample in the audio and > adjusts all samples based on that one.

Get a flat gain, and add two points- one almost completely to the left, one almost completely to the right. Reduce the volume of those points to 50%. The result should look something like the following (except with steeper slopes): 100% \ / \ / \______________/ 50% Save it as 'peak reduce'. When you apply this curved gain to a peak, it will do a very fast fade-out to 50%, then keep it at 50% for the duration of the peak, and then fade in again to 100%. This should take care of your "Whacks". I've also had success using it as a pop-filter for loud 'P's and 'B's (although an actual pop filter is less work). Make sure to audition the result (although I find most of the time it works like a charm). After you've reduced the main trouble peaks, you can use the regular normalize function.
