After initializing the I2S stream, if you need to reuse the same I2S interface (e.g., with audio_codec_new_i2s_data), you can simply pass the handles through the audio_codec_i2s_cfg_t structure. If you choose...

To reuse the I2S interface, configure the audio_codec_i2s_cfg_t structure with the same i2s_port value as your i2s_stream initialization.

The speaker's output is the voice signal captured by the microphone. If used as a reference signal, it may have high correlation with the input signal, causing AEC errors. May...

Thank you for your question. After testing, we found that you are using stereo format for playback, but the AEC algorithm outputs mono data. You may try modifying the buffer...

在新版本的 i2s_stream_idf5 中，没有对 MONO 状态下指定声道，可以在 create_i2s_stream 函数中加入如下代码： `i2s_stream_set_channel_type(&i2s_cfg, I2S_CHANNEL_TYPE_ONLY_LEFT);` 即可正常录音

You can modify the CMakeLists.txt file as follows to add `custom_board` to the environment variable `COMPONENT_ADD_INCLUDEDIRS`: ``` # Edit following two lines to set component requirements (see docs) set(COMPONENT_REQUIRES) set(COMPONENT_PRIV_REQUIRES...
