so, when i put music on audacity and then i record me singing to the music my vocals sound as if i’m singing with a cotton ball on my mic or something ( this is not the case, my mic is actually pretty good ( i think ) ) This is probably just a newb problem ( ive been using audacity for about… idk 3 weeks ) but when i search for an answer i dont exactly get the right thing. ( also, the thing said state your vers. of windows so windows 10 ) Im just not good at this i guess. I cant follow simple directions 'cus im dumb xD but yea… i have no idea what is wrong.
I got a pretty good idea. How do you have your microphone connected?
Lots of detail: “I plugged my Frammis model 4 microphone into a Signal-Spritzer Preamp…”
Are you overdubbing? Singing to the music playing in Audacity and then recording your voice.
Be accurate. Those jobs or descriptions can cause voice damage in a different way.

my mic is actually in the computer ( im using a laptop but again, xD my mic isnt the problem because when im recording with it it sounds fine and my voice is clear 
) and yea, the thingy kabob says overdubbing but idk if thats the problem. (also sorry is i seem rude or dumb xD im not good with ppl )
That works. I have recorded temporary voice tracks for a television commercial with a built-in microphone. As long as you’re not expecting Warner Brothers Studio quality, its usually good to go.
Overdubbing is where you have one track as a background or rhythm. Switch the system to overdub and when you record your microphone it plays that background track to your headphones so you can stay in rhythm or pitch. When you get done, you’re supposed to have two tracks: the original background track and your voice. You can do it again and add a guitar and do it again to add a banjo. Each one ends up on its own blue wave track stacked up top to bottom.
You can edit each one or change the volume or do whatever production you want.
Audacity will smash the whole thing down to one single sound file when you Export. If you want to keep the whole pile to edit later, Save an Audacity Project. Please note Projects will save all the tracks right where you left them, but will not save UNDO.
Do you like to record YouTube or other sound from the internet? The settings to do that can really mess up Overdubbing.
You are using headphones, right? You should be using headphones any time you have a live microphone.

Boosting frequencies above 2000Hz , & reducing those below 200Hz (on the vocal track only) will make it sound less muffled.
Audacity has a built-in equalizer which can enable you to do that, ( but it doesn’t work in real-time 
There are free equalizer plugins for Audacity [on Windows] which do work in real-time e.g. https://forum.audacityteam.org/t/very-nice-free-vst-plugins-from-voxengo/40911/2
