AFE frame AEC etc algorithm need hardware support? (AIS-1642)

[WangShuoran]

In your doc https://docs.espressif.com/projects/esp-sr/zh_CN/latest/esp32s3/audio_front_end/README.html show all of AFE algorithm.

I have ESP32-LYRAT_V4.3 want to use all of last picture algorithm. But I don't know the hardware requirements for each algorithm.

My Question is ESP32-LYRAT_V4.3 support all of the last picture algorithm?

The following question is a sub question of the previous question:

1. Does the AEC algorithm require ESP32S3 to have two I2S hardware connections( SPEAKER and MIC )?

ESP32 does not support all algorithm. I recommend to use ESP32-S3.

AEC need SPEAKER and MIC signal, but one I2S can get those at the same time. Please refer to esp32-s3-korvo-2.
