Monkey’s Audio is a fast and easy way to compress digital music. Unlike traditional methods such as mp3, ogg, or lqt that permanently discard quality to save space, Monkey’s Audio only makes perfect, bit-for-bit copies of your music. That means it always sounds perfect – exactly the same as the original. Even though the sound is perfect, it still saves a lot of space. (think of it as a beefed-up Winzip™ for your music)
The other great thing is that you can always decompress your Monkey´s Audio files back to the exact, original files. That way, you´ll never have to recopy your CD collection to switch formats, and you´ll always be able to recreate the original music CD if something ever happens to yours.
