Neutrino A-1608AEC DSP Processor with AEC
Acoustic echo is inevitable whenever a loudspeaker is placed near a microphone in a full-duplex communication application.
This is the case in speaker-phones, audio and video conferencing, desktop communication, and many other communication scenarios. In all those and similar communication scenarios, the voice from the loudspeaker is inevitably picked by the microphone and transmitted back to the remote speaker.
This makes the remote speaker hear his/her own voice distorted and delayed by the communication channel, which is known as echo. The longer the channel delay, the more annoying the echo becomes until it makes natural conversation impossible and decreases the perceived quality of the communication service. It is therefore absolutely necessary to avoid transmitting back the echo picked by the microphone.
AEC echo cancelling algorithm is included on top of the DSP modules existing in the standard Neutrino Series.
