My audio is a terrible high pitch screeching noise and I am having a lot of trouble getting rid of it. I’ve tried playing with the Noise Reduction, Graphic EQ, and the Filter Curve. It seems like I can’t get rid of the noise without losing my own voice too!
I’m a complete Audacity beginner…I’ve attached the audio file and would greatly appreciate some advice on how I can get rid of that screech!
Audacity version 2.3.3
Windows 10 Home Version 1903
That’s pretty badly banged up. Do you have a sample
before you did anything to it? I assume the original recording didn’t sound like a bad cellphone call.
Unfortunately, this is the original
. I recorded it on my laptop.
I think most of that is your laptop internal fan. Whatever you did, don’t do that any more.
This is brute force killing each whistle individually with Notch Filters.

I also applied the Audiobook Mastering filters to make it louder and get rid of the low-pitched rumble sounds.
In My Opinion you overused Noise Reduction and once you do that, there is no recovery from the honky, wine-glass sound.
You are a candidate for the Special Hollywood Filter. Write down what he said and have an actor read into a good microphone in a quiet, echo-free room.
Koz, you’re a wizard. I went through your steps and it sounds so much better, thank you.
What does the ACS-check do? When I ran it, it says the left and right channel fails to meet ACS requirements. Noise floor exceeds ACX specifications of -60 dBFS.
I’ve attached a picture of the message.
