BBC Sound Effects Library (FLAC) - The Full 60 CD Collection

FLAC is the acronym for "Free Lossless Audio Codec". It's an audio-specefic file allowing lossless compression; Meaning the file size is compressed without any loss in the audio quality. It's similar to zipping, but FLAC gives you way better compression because it's designed specifically for audio files.
NOTE: Certain audio software like Soundbooth (as of cs5 anyway) or Audition 3.0 can't open FLAC files. If your audio software can't read an .FLAC file.... Then use the Audacity audio program to first open the file, and then export it as a WAV for use in your preferred audio program... Audacity is an open-source audio editor, it's able to read FLAC files and is freely availible to anyone.

The BBC Sound Effects Library is comprised of 60 cd's, Giving you a vast resource of diverse, royalty-free sounds recorded by the BBC's top engineers.
