Hi guys,


I made some tests with this decoder...So, here is my results :

Tools :
 - mkvtoolnix 1.4.1
 - wavpack 4.2 beta 3
 - WavpackDShow Filter 20050321-2
 - Haali Splitter 20050322
 - MPC 6.4.8.4

Comments : All seems to be fine. Good work Toff ;-) Just one issue during the
mux process with mmg. I've a warning at the end ( "wavpack_reader : non_audio
block found") for the files with a Sampling-Rate inferior to 44100 Hz. However
the playback works fine. But it's concern much more Mosu'stuff...;)
