9 FUNCTIONAL DESCRIPTION

9.8.9 SCI_HDAT0 and SCI_HDAT1 (R)

For WAV ﬁles, SCI_HDAT1 contains 0x7665 (“ve”). SCI_HDAT0 contains the data rate mea-

sured in bytes per second for all supported RIFF WAVE formats. To get the bitrate of the ﬁle,

multiply the value by 8.

Note: if bitrate is over 524280 bit/s, SCI_HDAT1 value saturates to 65535.

For AAC ADTS streams, SCI_HDAT1 contains 0x4154 (“AT”). For AAC ADIF ﬁles, SCI_HDAT1

contains 0x4144 (“AD”). For AAC .mp4 / .m4a ﬁles, SCI_HDAT1 contains 0x4D34 (“M4”).

SCI_HDAT0 contains the average data rate in bytes per second. To get the bitrate of the ﬁle,

multiply the value by 8.

For WMA ﬁles, SCI_HDAT1 contains 0x574D (“WM”) and SCI_HDAT0 contains the data rate

measured in bytes per second. To get the bitrate of the ﬁle, multiply the value by 8.

For Ogg Vorbis ﬁles, SCI_HDAT1 contains 0x4F67 “Og”. SCI_HDAT0 contains the average

data rate in bytes per second. To get the bitrate of the ﬁle, multiply the value by 8.

When FLAC format is detected, SCI_HDAT1 contains “fL” (0x664c). SCI_HDAT0 contains the

average data rate in byte quadruples per second. To get the bitrate of the ﬁle, multiply the value

by 32.
