+ * These are the scalefactor values for Layer I and Layer II.
+ * The values are from Table B.1 of ISO/IEC 11172-3.
+ *
+ * There is some error introduced by the 32-bit fixed-point representation;
+ * the amount of error is shown. For 16-bit PCM output, this shouldn't be
+ * too much of a problem.
+ *
+ * Strictly speaking, Table B.1 has only 63 entries (0-62), thus a strict
+ * interpretation of ISO/IEC 11172-3 would suggest that a scalefactor index of
+ * 63 is invalid. However, for better compatibility with current practices, we
+ * add a 64th entry.
