pipeline_a2dp_sink_and_hfp application with aec algorithm technically can I import? (AUD-7223)

Hi all,

Technically, can I add the AEC algorithm to the pipeline_a2dp_sink_and_hfp example?

[jason-mao]

Integrating AEC into the HFP project on ESP32 is feasible, and the performance at an 8 kHz sample rate is good.
Are you evaluating this for a new project? We plan to release a new esp_bt_audio component next week, which will include this example for direct use.

Yes, we are considering using it in a mass-produced product. Which development board did you use for your tests? Could I get your schematic suggestions?

For example, I am not using both i2s slots simultaneously with the codec on my card (for DAC and ADC). Will this cause problems for the algorithm? We would appreciate your help with issues like whether microphone feedback is necessary.
