what a file after acmConvert

[Dirk Reske]

Hello,

I've tried to convert a MP3 file to WAVE using the Audio Copression Manager.
my Destination format is: WAVE_FORMAT_PCM
All works fine
what a file Type do I get then?
When I try to open it with media player, it says that it is an unknown
format

Wrong newsgroup, but my bet is that you have forgotten to update chunk sizes
in the RIFF header

ohh...sorry.
I uses this code:

I can't open the output file

Yes, this sample does not write RIFF header at all. It produces raw PCM.
This gives you some idea of the riff format:

but it is in fact very poor if simplified reference.
The best thing to do would be to read documentation on
mmioReadChunk/mmioWriteChunk in MSDN library
