use24 on/off: This is only valid for
SD and selects between 24bit and
20bit sound.
del off/on delay12 delay34: For
each of the embedder groups the
delay bits for ch1+2 and for ch3+4
can be inserted into the ACP. The
delay value can be positive and
negative and is put directly into the
ACP as it is written.
Note: To set both delays to 0 would
be the same as turning the delays off.
The response reflects this.
