’0’..’7’ - Channel number is equal to
(d+1)
ee:
This is the hexadecimal value of the second byte of the Audio
InfoFrame. This field specifies the sampling frequency and
sample size reported by the source.
The 7-5 bits of this byte are reserved and shall be zero.
The 4-2 bits determine the sampling frequency:
000 Unspecified 100 88.2kHz
001 32kHz 101 96kHz
010 44.1kHz (CD) 110 176.4kHz
011 48kHz 111 192kHz
The 1-0 bits determine the sample length if the format is PCM:
00 The sample length is not specified by source
01 16 bit
10 20 bit
11 24 bit
For example ’0F’ means 48kHz sampling frequency and 24 bit
sample length.
ff:
This is the hexadecimal value of the fourth byte of the Audio
