[Valer Nur]

Hi Shrikant,
If the problem was not solved yet, you can always used a centralized AEC/NR like PBXMate.

Hi
I need to implement echo canceller in my audio application.I am sending audio alsasrc to remote mobile android app from my hardware.The command is as follows:
Sending and receive combined in single command:
"gst-launch-1.0 -v alsasrc ! audioresample ! audioconvert ! audio/x-raw, format=S16LE, layout=interleaved, rate=8000, channels=2, endianness=4321, width=16, depth=16, signed=true ! udpsink host=$1 port=5001 & gst-launch-1.0 -v --gst-debug-level=4 udpsrc port=5003 ! audio/x-raw, layout=interleaved, rate=8000, format=S16LE, channels=2, endianness=4321, width=16, depth=16, signed=true ! audioconvert ! autoaudiosink"

But right now I am doing push to talk to avoid echo and noise on the hardware side.
Please tell me how to implement AEC in GStreamer.....

Thanks,Shrikant_______________________________________________
