High pitch noise with all mics

The link says the video has been removed but my guess is a ground loop picking up noise from the power supply in your computer. Use balanced cables and don't bypass the ground when plugging gear into the wall or don't use an outlet without a ground.

My computer gets fired by 2 different jacks. I guess that is what is causing it.

The broken English and vapid monologue made it impossible to listen for very long, but the only issues I hear are plosives.

I like windshield a lot more because they are small. But I heard it distorts the high frequencies.

Back away from the mic. I'm hearing mostly plosives and sibilance issues, also occasionally some distortion. Backing up will help, sometimes only a few inches. You'll get a more natural sound that way.

Of course, backing up can introduce other problems, especially if your room is not acoustically treated.

Ok I can do that, but do I need a popfilter?

well I guess I don't even need a pop filter anymore. Increasing the distance between me and the mic helped a lot!
I really thought if I get that far from my mic the recording will sound ****ty like it did before when I still used my USB mic. But to me it sounds even better and as if my room was treated, no!? I guess I'd get an even better sound with room treatment, but I'm astonished how good it already sounds, and this with an only 73$ mic.

Room isn't even treated.

What do you think?

Put treating your room on your list of things to do.

That short clip definitely sounds better. I didn't notice any glaring distortion in the clip, but if you are still experiencing it then either back off some more, turn down the mic preamp gain, or both.

And yes, treating your room will help a lot.

I also lose quality when I put the wave file from Audacity to Sony vegas and then create the video. The afterwards audio is pretty bad, althouhg I set sound quality on high on vegas.

Ok now I figured out what messed up the quality of my sound: Handbrake, a program to decrease file size.
Sony vegas wasn't the issue here.

still messes up my sound!!!!
My recording loses all the good bass after compression

That is what lossy compression does to save so much data space: it gets rid of what it thinks you will not notice, including bass and highs and what it deems to be background noises. If Handbrake will allow you to have a less compressed track try that, eg. a 256kbps MP3 file will have fewer data deleted than a 128kbps MP3 file.

I think it sounds OK now.
#I changed "Dolby Pro Logic" to "Stereo" in Handbreak audio output, just like it is set in Sony Vegas.

That solved it, I think. It sounds clean now.
But I still have grounding issues.

The distortion caused by the grounding issue might not be noticable to you, but I can hear it slightly and I want to fix it:

Handbrake is still ruining my audio quality!!!!
Is there a program that decreases file size but doesn't destroy the good audio!?

This is the room acoustics forum; you would probably get more help by posting this in a more appropriate forum.
