Sound loses quality in Audacity

Hello there! I risk this being a very silly and basic question, but I´ve been using music in Audacity for a while (for podcasting) and it´d never happened. This is the first time I try to use a song from a CD though, but the thing is that the .wav file sounds great when played on WindowsPlay and real lame when I bring it to Audacity (kind of muffled and low). Any tips? Thanks guys! I have Audacity 2.1.2 on windows 8

The Windows player may have a built-in equalizer which is boosting the treble.
Audacity has an equalizer , (but adjustments can’t be made in real-time*).
Audacity has a BassTreble effect which you could use to boost the treble and/or cut the bass to get rid of the muffled quality.

[ * Free equalizer plugins are available for windows which work in real-time , e.g. ]
