[Speex-dev] Denoiser and echo cancellation in FIXED_POINT

Hi all,

I'm developing a VoIP application for my IPAQ 5450 and from some moths
i'm using speex as codec.

Now is the time to obtain the best possible audio quality. As my PocketPC is
a smartphone my main problems are the echo cancellation and the noise. As
the first one can be
solved by using headphones how can i solve the second?

Do someone have some hint for me regarding the denoiser as it is still not
ported in fixed point?
Are there other Opensource/free patents denoiser avaible for fixed point


I apologize for my english
