Bits 0..7 define the sampling frequency and data format:

0 = MPEG2 / 22.05 kHz

1 = MPEG1 / 44.1 kHz

2 = MPEG2 / 24 kHz

3 = MPEG1 / 48 kHz

4 = MPEG2 / 16 kHz

5 = MPEG1 / 32 kHz

6 = u-Law 24kHz mono

7 = u-Law 8kHz mono

8 = a-Law 24kHz mono

9 = a-Law 8kHz mono

10 = PCM 24 kHz mono big endian

11 = PCM 8 kHz mono big endian

12 = PCM / 24 kHz 16bit mono little endian

13 = PCM / 8 kHz 16bit mono little endian

14 = G.711 uLaw / 32 kHz mono

15 = G.711 uLaw / 12 kHz mono

16 = G.711 aLaw / 32 kHz mono

17 = G.711 aLaw / 12 kHz mono

18 = PCM / 32 kHz 16bit mono big endian

19 = PCM / 12 kHz 16bit mono big endian

20 = PCM / 32 kHz 16bit mono little endian

21 = PCM / 12 kHz 16bit mono little endian

22 =PCM / 44.1 kHz 16bit mono big endian

23 = PCM / 44.1 kHz 16bit stereo big endian

24 = PCM / 44.1 kHz 16bit stereo little endian

25 = PCM / 48 kHz 16bit stereo little endian

26 = PCM / 48 kHz 16bit stereo big endian

In MPEG modes the bit 15 selects the bitrate mode:

0 = VBR

1 = CBR

For VBR the bits 8..14 contain the encoding quality 0..7. 0

being the lowest quality and 7 being the highest quality.

For CBR the bits 8..14 contain the bitrate in kbps/8, i.e. in
