ok, it seems as i found the error. When reading a wav file, i used 
read_header(), and then started with read_fragments(), wrongly assuming reading 
will begin at the right position, in fact it begins 8 bytes too soon ("data" 
keyword + audiosize (4 bytes))... this explains why the files grow in size, and 
why i had this ugly click.
So before reading a file, skip_header() must be called, regardless if 
read_header() had been called or not. Alternatively, rewind_audio() can be used.

So i can continue to split a few concerts to wav-tracks in order to make CDs... 
and continuing working on praf !
