about half as much space on a disc. Level B is used in both the CD-i and CD-ROM XA formats; this method of recording audio
offers medium fidelity but is more highly compressed than level A. Used in both the CD-i and CD-ROM XA formats, level C is
a method of recording audio that offers fidelity sufficient for speech. It is highly compressed.
