, released in early 2003.
It compresses an audio CD to a range of 206 to 411MB, at bit rates of 470 to 940 kbit/s. The result is a bit-for-bit duplicate of the original audio file; in other words, the audio quality on the CD will be the same as the file when played back. WMA Lossless uses the same .WMA file extension as other Windows Media Audio formats. It supports 6 discrete channels and up to 24-bit/96kHz lossless audio. The format has never been publicly documented, and support for it remains limited outside of Windows-based PCs.
