* -----------------
|
|

|
|
* version v3 w/ 14_4/lpcJ is ok.
|
|
* version v4/5: - atrac3 is ok.
|
|
* - cook is ok.
|
|
* - raac, racp are ok.
|
|
* - dnet is twisted "The byte order of the data is reversed

* from standard AC3"
|
|
* - 28_8 seem problematic.
|
|
* - sipr should be fine, but our decoder suxx :)
|
|
* - ralf is unsupported, but hardly any sample exist.
|
|
* - mp3 is unsupported, one sample exists...
|
|
*
|
|
* Real Audio Only
|
|
* ---------------
|
|
* v3 and v4/5 headers are parsed.
