Tool/software: Linux
Hello,
We are in the process of design a new hardwar wiche is IP intercom based on raspberry pi and SIP (voip), but we have problem of echo (part of sound played from the speaker is reflected and picked up by the micro wiche is near from the speaker), so that's why I ask if there is any smart codec withe dsp for accoustic echo cancellation or any software solution ? thank you.
Best regards.
