大家好！

我们希望采用ESPNOW的通讯模式实现高清音频数据的传送。ESPNOW默认一对一速率是1mbps。我们是否可以通过提高速率（ esp_wifi_config_espnow_rate）的方式来实现音频传送？

谢谢

我使用的是ESP32-S3-Korvo-2开发板，当我进行voip进行通话的时候显示 `Initial ONE-MIC auido front-end `，这应该说明voip只是使用了一个microphone?如果只使用一个microphone的话，使用的是哪一个？

Hi

Dear Friend

I found ESP32-S3-Korvo-2 use the MSM381A3729H9BPC MEMS microphone. It's sensitivity -38dB. Now, I select another microphone(AP3722AT) instead of it. but, AP3722AT's sensitivity is -42dB. I test AP3722AT's microphone level is lower. if I must use -38dB microphone or How to change the ...

Dear

I test use esp_layraT test voip function. aec working fine. now, I use ESP32-S3-Korvo-2 test voip function. found aec function not working or working not good. I think maybe I need to adjust aec delay. I don't how to change aec delay ?

Can you help me? or maybe other problem?

Dear support

我希望将wwe和voip融合到一起。通过wwe唤醒并且语音呼叫voip进行拨打电话。我看到wwe和voip采用了不同的音频处理代码。我不知道是否可以将两个代码融合到一起。采用统一个套代码。这样子可以实现wwe唤醒并且呼叫voip的功能？

谢谢
