High Performance Echo Suppressor For PJMEDIA

If you were unhappy with the performance of echo suppressor in PJMEDIA, specially on mobile devices, This is partially due to AEC, Acoustic Echo Canceler cannot be used on these devices due to the high processing requirements.
PJSIP group has whipped up a completely new echo suppressor, and according to a post on the PJSIP Blog, it works better than before. I have had no time to test yet but will be working on doing so next week.
In tests conducted by the development team, on PocketPC 2003 PDA with 312MHz StrongARM CPU,(which I am using for mobile tests as well) it only used less than 0.5% (half percent) of CPU.Not only that it used a very little CPU power, it was able to suppress echoes! That indeed is good news.

The new echo suppressor is available in SVN at pjmedia/echo_suppress.c, and it will be included in the next release.
