ESP32S3上使用ESP-SR时 给SR feed两个麦克风的数据 只会输出第一路的数据 不管有没有第二路
比如说我现在拔掉第一路，第二路不动，说话没用
但是第一路不动，第二路不管在不在都正常
我看手册MISO选择信噪比高的一路音频输出这个是需要开启还是？
说明下：SR我使用了aec ns vad agc
我确认了板子上两个麦克风是正常的。

I am working on integrating the ESP-ADF AEC algorithm into my existing full-duplex audio project to eliminate speaker echo.

### Hardware
Board: ESP32-S3 Korvo-2 V3.1
Verified hardware is working correctly (as the official ADF AEC example on the same board works correctly with AEC)

### Project ...

Hi everyone,

I’m trying to get AEC (Acoustic Echo Cancellation) working with a custom board that uses the ES8311 codec for a single microphone and speaker setup.

I’m using the ESP-ADF VoIP example (Release v2.7, commit 9cf556d) and have modified the board files to match my custom hardware. Both the ...

ES8388 好像不支持硬件回采，也就是说它并不支持硬件回采后的 AEC , 只能支持软件回采也就是这里说的 https://github.com/espressif/esp-adf/bl ... m_stream.h type1、type2 的区别
如果您需要软件回采，得参考这里说明配置一下才可以

ps: 对于算法而言，硬件回采效果要优于软件回采效果；如果需要双入双出的话可以考虑 ES8389
