+ * 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.
