<DIV><FONT face=Arial size=2><FONT face="Times New Roman" size=3>Hi
All,<BR>
I have one doubt, suppose we have conference between 3 users (PCM<BR>companded
voice channels) then we add the streams together with scaling but <BR>data which
a user can receive will include his own voice information also<BR>or i think we
should substract his info. from the combined data,<BR>also as the total sum of
scaling factors should be 1 how we decide these<BR>scaling factors becoz these
factors decides audio gain of each
channel?<BR>
Can you plz suggest me steps to follow to implenent voice conference using DSP(I
am using Fixed point DSP TMS320c55x) and Components to use from DSP and level of
buffering for incoming
data.<BR> Thanks in
advance.<BR>Rahul jadhav. </FONT><BR></FONT></DIV><FONT face=Arial size=2>
