(Moved here by moderator)

Hello, Everybody,

I hope this is the right place for DAW questions.

I have some sibilance in my voice. I have done some things at the source to help correct, but it still slips through.

So, I'm trying to "notch" it out with my DAW I'm using Audacity and the built in notch filter effect. I have totally isolated the "sss" sound to 900 hz. I know that sounds crazy low, but so is my voice. I can completely eliminate the sibilance by notching out that frequency, but then the result sounds kind of muddy.

Any suggestions for brightening up the file once I've taken out all the 900 hz frequencies?

Thanks

Paul

These types of questions usually go in the gear or chat sections, but I would recommend using a De-Esser instead of a notch filter for sizzly esses. A De-esser is basically a frequency-targeted compressor, so it only kicks in when the set frequencies get too loud...leaving the audio largely untouched (when set up correctly). 900Hz is not a typical sibilance problem area though, it is usually in the higher frequencies. You sure you don't mean 9000Hz?

Audacity doesn't have a De-Esser built in though. You can probably find a freeware plugin or if you have a Mac you can accomplish de-essing with the AU Multiband compressor. You will want to do some research so you fully understand the process in order to set it up correctly though.

Spend some hours on Google researching De-esser and Compressor. You'll benefit from a good understanding of the processes.

I'm not endorsing this product. I've had a few people mention it in the past and its on sale for $29 until tomorrow.

Again, i've never used it but I've heard good things. For $29 it may be worth a shot.
Never used Audacity so make sure that it will even run this type of plugin!

Paul, are you able to send me some audio? If you can, please send about 30 seconds worth of the already-recorded audio you find troubling, and also please make a new raw recording of the same material without whatever you've done at the source (or anything else) to eliminate the issue.

I'd like to hear, see and analyze the audio using Adobe Audition.

Thanks.

I downloaded your file, I listened, and then I let it display it's frequency response in graphic form. (Using Audition)

I don't SEE and 900 hertz problems. If I had not read your posts about the problem with S-sounds, I don't know that I would have even noticed them. They didn't strike me as all that outrageous. And in Audition, I couldn't come up with a quick-fix that would reduce them. Maybe someone else can help you there.

But I do have one suggestion. Your graphically displayed audio on the low end begins a good healthy nosedive below 70 to 75 hertz. But then at about 50 hertz, it begins to rise like a rocket!!! It peaks at about 13 hertz. You can't hear it, but when people put their meters on your dead spaces, your room tone, your noise level readings are corrupted by this 13 hZ trash. I would suggest you run a high-pass filter to take out stuff below 70, 80 or 90 hertz. Where you want to begin the cut is a matter of personal choice.

That's great feedback thanks. Maybe my perception of my "hsss" in my voice is worse than reality. Good problem to have.

Another reason to have a coach...but in the meantime, thanks for the 2nd set of ears.

Be sure to check the spec on your hardware hpf. I have personally seen a few hpf on mics that cut as high as 140-150 hz. Horrible hardware setting for someone that has any bass in their voice.

True dat! And, most hardware HPFs don't cut nearly as much out as one might cut out using software.
