NXP i.MX 8M Pico-Pi Sound bar reference design integrates 3.1 channel playback processing together with TalkTo multichannel AEC and Adaptive Interference Canceller (AIC) running on one of the i.MX 8M Arm® Cortex®-A53 cores to provide far-field voice activation up to 6m+. The reference design can be extended up to 7.1 channel playback with the corresponding multi-channel AEC algorithms from DSP Concepts.
