028 * A SyntaxChecker which verifies that a value is an Audio according to RFC 2252.
029 * 
030 * The encoding of a value with Audio syntax is the octets of the value
031 * itself, an 8KHz uncompressed encoding compatible with the SunOS 
032 * 4.1.3 'play' utility. We implement it as a binary element.
033 * 
034 * It has been removed in RFC 4517
