Microphone - Noise in the microphone, nothing helps ...

Question

Hello. I have a microphone that doesn't record sound "clean". In the background you can hear slight noises and distortions. The voice can be heard...

It is more of a hum. I had this problem too. You don't have grounding in the outlet.
If you are using a laptop, disconnect the charger. There should be no noise then.
Touch the USB contacts and a metal part of the microphone at the same time. Check if the humming has gone away.

Buying an external USB sound card can help, cheap for a few zlotys, but all analog circuits are away from the motherboard. https://www.google.pl/search?q=usb+sound+card...&spell=1&ei=UOlYVJTpPMLTaKmUgdgE&ved=0CBEQBSg

or maybe there is some other way? maybe some program can fix it?

DominTR3B · Answer

Noises are generated in the analog path, the programs only cut out noise samples, eg "Audacity". The best solution is a good shielded preamplifier with a symmetrical input.

Indeed, when I disconnect the power supply, the hum subsides, but you can hear a slight noise, but GoldWave made the noise also disappear and it's okay, but there is one problem. I need good audio quality in order to record videos on YouTube (games), and as you know, games eat up a lot of battery and here's the problem because if I want to play longer without hum (without power), I will record for a shorter time. Do you have a way to remove this hum when the power source is connected to the laptop?

Do you have a dynamic microphone (PLN 5 and more) or a condenser microphone (PLN 200 and more)? If it's headphones, it's 90% dynamic.

the one attached to the headphones which is probably cheap

Approx.
If you don't want to keep touching the USB housing / contacts, you can take the wire.
Tie one end to the computer housing (e.g. on the net), REMOVE THE PAINT WHERE YOU BINDED and the other end just this metal part of the microphone.
For convenience, you can take a microphone from your desk, you don't even need to have this wire next to you if you have headphones ;)

And the noise (not hum) cannot be eliminated, only you can equip yourself with a better microphone so that there is no such noise. In my opinion, the USB microphone has less noise because it is not an analog signal, but a digital one, so with virtually no loss or distortion of the signal.

and if I connected the charger to an extension cord with grounding, would it help?

It should work, but if there was no grounding in a socket, there is probably no ground in the whole house.
I don't know how I can help.
A moment ago, I also removed the hum from the microphone ( coincidence, a few days ago it started to be like that! ), I did it in such a way that I put one end of the wire on the microphone and the other end on the microphone input terminal. Humming then 0%!
