Dynamic Range Compression Cut Scale Factor
0 to 0x7FFF (at ‘0’ the compression is minimum, at
0x7fff the compression is maximum).
(default: 0x 7fff)
Dynamic Range Compression Boost Scale Factor
0 to 7FFF (at ‘0’ the boost is minimum, at 0x7fff the
boost is maximum).
(default: 0x7fff)
PCM Scale Factor
0 to 7FFF (default)
Output LFE Present

SPDIF Output Stream Format
(the SPDIF output can send either the PCM decoded
output, or the input encoded elementary stream)
AC3/MPEG (default)
00
PCM
01
SPDIF Output Latency
Delay between the decoder and the bitstream sent via
the SPDIF output. The delay is expressed in multiples
of 1/Fs, where Fs is the sample frequency. The delay is
signed.
0xffff to 0x7ffff (default: 0)
