Best website/application for downloading ".WAV" music files with a
wide variety of genres (sort of like iTunes but with uncompressed
files available).

Beatport.com is a good example but they have too few genres available.

Hi there,

This may be what you are looking for:

You have access to over 1.4 million tracks and has full rip and burn software.

Cheers.

I believe what you're after is .flac files. There are no .wav download
sites (at least that I know of) but there are sites where you can
download .flacs.

"FLAC, an acronym for Free Lossless Audio Codec, is a popular format
for audio compression. Unlike lossy codecs such as Vorbis, MP3 and
AAC, it does not remove any information from the audio stream and is
suitable both for everyday playback and audio archival."

http://en.wikipedia.org/wiki/FLAC

Flac's are perfect digital reproductions. They do not have sounds
"stripped" from them by lossy codecs such as .mp3, .wma etc...

Unfortunately because of this they are a fair amount bigger than their
lossy brethren. A 4 min song encoded in .mp3 is probably 3-6 MB, flac
might be from 20-30MB. Because they are a fair amount bigger they're
not very popular with legal download sites (because of the extra
bandwidth required to serve them off).

You can play a .flac in almost every popular music player and they
downloadable through "illegal" file sharing bit torrent clients like
azureus (http://azureus.sourceforge.net/) or mIRC.

I would suggest using the pirate bay (http://thepiratebay.org/) to
find flac audio. Just search for the word "flac" under audio and
you'll do fine.

Do the Pepsi challenge, listen to an mp3 and then a flac of the same
song in a decent set of headphones and the difference will surprise
you!
