## Benefits

#### Reliable Far-field performance

- DSP Concepts’ cutting-edge algorithms to cut through the loud music or kitchen noises in living room
- AVS 1.7 far-field and Google ART certified algorithms
- Best-in-class barge-in and wake word detection performance

#### Support for high resolution audio playback

- Multi-channel audio playback for immersive sound applications on smart speakers and sound bars
- 3 channel AEC to effectively cancel out the multi-channel playback signals

## Audio Front-end Features

#### DSP Concepts’ TalkTo for excellent far-field performance in noisy environments

- • 4-mic Beamformer with Single Channel Noise Reduction (SCNR)
- • State-of-the-art noise cancellation with Adaptive Interference Canceller (AIC)  
    - ○ No reference signal needed
    - ○ Eliminates 25+ dB of external noise sources such as background music or a booming movie
- • 30+ dB Acoustic Echo Cancellation (AEC) for excellent music barge-in

#### Support for 3.1 channel playback processing
