Hi, thanks for your answer but if that was the case I should listen ALL my pc audio files and songs with that enhancement and im not. Im just experimenting a bottle neck on my audio quality only on my obs recordings. I think my fix is tweaking the audio output settings on obs.If you feel you hear audio compression, that might also be a feature of your media player or by Windows sound settings itself (Windows sound->Playback tab->choose your device->Enhancement tab->deactivate all sound effects. This is for your speakers.
There is a similar setting for some recording devices as well (your mic), depending on the driver. Some have "enhancements", some do not.
