[Speex-dev] Mixing 16-bit signed Digital Sound

[Fabio]

Hi all,

I hope i'm not too out the scope of this mailing list, but i'm sure someone
can help me.
I'm using speex in my VoIP application and now i need to Mix two decoded
stream in one.
I'm using speex i'n narrow band mode, 16 bit per sample in fixed point. As
the decoder output is
a 16-bit signed sample. How can i mix two such samples? Do some one have a
formula?
I other words i'm tryng to mix decoded transmission stream and receiving
stream in one.

Thanks in advance
Fabio
