when you 'rip' a cd file/song, don't use any compression options(aka mp3 or wma etc)and it will be in an uncompressed wave file aka the highest quality. :)
to check click on the file. if using windows, near the end of the list is something called properties. onr the tabs in properties when have info such as number of chaneels,the compression rate etc....if you see numbers like 16 bits, 44100 for frequecny, 1 to 1 ration uncompressed etc. yep you've defenitely got the wave/wav. file in it's highest fidelity. :)
the drawback is this does take abit more size on your computer.
hmm sorry i'm not familiar with winamp,i'm usually just listening to cds while net surfing/so i'm very behind on the media player 'wars'
i fond of exact audio copy for 'ripping' it's free a program you can download. :)
