why set aec_init to false for esp32-box board? (AIS-1181)

code: https://github.com/espressif/esp-skainet/blob/master/examples/wake_word_detection/main/main.c#L96 why is esp32-s3-box special from other s3 boards?

I think it's just to reduce CPU loading and memory size.

int nch = afe_handle->get_channel_num(afe_data); int feed_channel = esp_get_feed_channel();

• afe_handle->get_channel_num(afe_data) 中返回的是 Mic 的数量（afe_config.pcm_config.mic_num）吗
• esp_get_feed_channel 是什么作用，为什么esp32-s3-box 上返回的是4，硬件信息里显示只有2个i2s。
