23 | * These are the scalefactor values for Layer I and Layer II. | ||
24 | * The values are from Table B.1 of ISO/IEC 11172-3. | ||
25 | * | ||
26 | * There is some error introduced by the 32-bit fixed-point representation; | ||
27 | * the amount of error is shown. For 16-bit PCM output, this shouldn't be | ||
28 | * too much of a problem. | ||
29 | * | ||
30 | * Strictly speaking, Table B.1 has only 63 entries (0-62), thus a strict | ||
31 | * interpretation of ISO/IEC 11172-3 would suggest that a scalefactor index of | ||
32 | * 63 is invalid. However, for better compatibility with current practices, we | ||
33 | * add a 64th entry. | ||
