What is Apple Lossless?
Unlike an MP3, this is a Lossless format, meaning that virtually every bit of the sound/information on the original recording is captured and almost nothing is lost in the coding and decoding of the song. As a proprietary technology of Apple, its use is limited to Apple-licensed devices (like iPods) and software (like Quicktime and iTunes). If you play your music through high quality ear buds, good computer speakers and/or your home stereo you will notice that the sound is as good as your CDs.
