is FLAC better than wav?

I use Media Monkey (get it here) to play and organize all the media files. As long as you have the FLAC codec installed (get it here) you will be able to use the program to play FLAC as well as use it to convert any other formats to FLAC.

As stated before, both formats are loss less, but FLAC compresses the file some what, so the files will be smaller, but sound just as good. If you don't have the room for a library of WAV songs (not many people do) then I suggest switching.

I also have the codec package linked by unofficial_GT_master and it allows me to play FLAC in Windows Media Player as well as Media Player Classic, which is good.

Finally, keep in mind that if you like to edit audio in any shape or form using Sound Forge, Audition, , Acid, etc... They will most likely not be able to read the FLAC files, you will need to convert them to another format to edit them.

Hope this helped!
