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.

  • Haythem,

    Unfortunately our codecs do not have integrated DSPs capable of Acoustic Echo cancellation. we do have very flexible, and simple codecs, but if AEC is needed, an external processor would be needed.

    best regards,
