0x92—Bits[4:2] Sampling Frequency

0x92—Bits[1:0] Ample Size

0x93—Bits[7:0] Max Bit Rate

For compressed audio only, when this value is multiplied by

8 kHz represents the maximum bit rate. A value of 0x08 in this

field yields a maximum bit rate of (8 kHz × 8 kHz = 64 kHz).

0x94—Bits[7:0] Speaker Mapping

These bits define the mapping (suggested placement) of

speakers.
