Is there a way to change the settings of the Healing Brush?
Also I noticed that it is using the "click/pop eliminator process" during the Healing, can you use the pain brush stroke in lieu of the Healing Brush when you want to select larger areas than the healing brush will allow? I've tried this, selecting an area then going and running the "click pop eliminator process" but it doesn't seem to have the same effect as the healing brush......any suggestions?

Thanks

The difference?

The healing brush is a frequency-selective version of fill single click now... (apparently, according to the developers), and that's the reason that you can't select a larger temporal area with it and still have it work. You have a brush size selection on the toolbar (just to the right of the tool select icons) from 3 to 99, and that's it. On a really big file, zoomed right out, even a size of 3 won't work.

I've been using the Healing Brush to remove some whistles, and some loud screams from concert audio. It works really great, but is just time consuming, I'd like to be ale to do it a little faster at times. I'm also trying to avoid the "squeal" sound I get sometimes when editing parts of the file, any suggestions?

Not a lot I can do about that! Although I have to say that if it's that sort of a concert, I'd generally leave them in.

Quite often, the harmonics of noises get separated - and it's not at all unusual to have to remove vertically separated sections to clear all the sounds associated with a particular noise. Chances are that if you have something left after removing the obvious bits, you are still looking at remaining artefacts in a direct vertical line, after all. One thing that can help to locate them is to select a smaller part of the vertical scale to work on; right-click on it and drag out a particular part to see more of it. When you've done this, you can drag the whole scale up and down with the left mouse button, so you don't have to keep zooming in and out all the time. The other right-click option that sometimes helps with analysis is to set the display to logarithmic frequency - but that rather depends on the material you have.

Yeah it does help to zoom in and out, move up and down the frequency to remove those sounds, but many times I still have a slight squeal, or a swishing sound, that's been impossible to remove, even after selecting all obvious sound and either using the healing brush or the paint brush and then lowering the volume (which seems to work the best, and is the quickest).

Whistles are so hard to remove for me, probably the hardest obvious noise I've had to remove.

Just a follow up to this thread, and for anyone who may be dealing with a similar issue, I've been trying to remove specific noises from an audience recorded concert material, specifically loud whistles, and yells that were close to the recorder in the audience. I first tried the healing brush with varying degrees of success, but it took alot of time to let the brush function run each time, and I could only select so much material because of the size limit allowed.

Next I went to highlighting material with the paint brush and lowering the volume or completling deleting the unwanted noise, sometime with great success, and other times, leaving a vaccum or hollow sound to that part of the audio, plus you had to chase the noise up the frequency scale and remove it there as well. Sometimes this worked just fine, but many times it did not.

The comes the generate noise function, and WOW did that do it. highlighting the specific material with the paintbrush, then apply generate nosie (usually pink) at the right temperature - color really did the trick, totally removing those sounds! The other sound around it dominates, and you do cannot hear the noise that's been generated, so long as it you keep it at the right level, so that it blends well. I still have to chase up it the frequency scale, but it comes across much cleaner, and is so much easier and quicker than previous attempts.

Hope this helps someone, it's helped me a great deal in making this material much more enjoyable to listen to without the annoying whistles and screams piercing my ear.
