IPP 5.3.4 Echo Canceller Update

jhr — Wed, 21 Oct 2009 10:07:55 GMT

Hi,

In IPP 5.3.4 release note you can read this about the echo canceller:

. Improved Echo cancellation issues in Speech coding function and Sample

Unfortunately there is no sample package for 5.3.4, the closest I can get is w_ipp-samples_p_5.3.101.zip which has no changes in the echo canceller code.

Where can I get the samples which contains this update ?

Thanks.

I understand, but I can't update to 6.x for now.

Since there is an improvement in 5.3.4 as stated in the release note I would like to be able to get it.

Can you get more information about this AEC fixed issues in 5.3.4 ?

Regards.
