I added MS ParamEqu filter ( which is a DMO ) into my graph using IDMOWrapper interface. I want to manipulate parameters of it ( gain,bandwidth,center freq) programatically in my code. When I searched for this , I found IMediaParams Interface ( http://msdn2.microsoft.com/en-us/library/ms785964(VS.85).aspx) But I am not sure that it will solve my problem. If you experienced changing parameters of a DMO fitler programatically , can you give me advices about that ? For example I didnt understand "envelope" concept. Also sample code for using that interface would be very good. Best Regards
