anybody have DSP specialism regarding live recordings ??   
Hi ... have a bit of a strange problem. Have constructed an audio mixer with 
WMF11. Mixing is done by summing the uncompressed 16-bit shorts from 2 
IWMsyncREader objects, adding the results and feeding the results into 1 
IWMWriter. Thereby I am taking care of clipping by making sure that the 
resulting sum of adding the shorts is never larger than the original signal 
of any of the 2 sources (is done by fading out one and fading in the other 
simultaneously). this works fine, no problem. However as soon as a live 
recording comes along (audience rumour, applaus etc ), results go beserk. Am 
I missing something here ??? As far as I can assess results, the incoming 
live recording sounds fine, but it seems to kill the results on the song 
fading out.

Basic question: are live recordings something to be taken into account (to 
be handled differently ???) in DSP processing ???

thx .. Steve
