ADF里面的algorithm例程没有效果

Postby 三木哥哥很懵逼 » Mon Nov 01, 2021 11:00 am

最近想试试ADF的回声消除,例程里的algorithm有这个功能,但是我用ESP32-LyraT V4.3和ESP32-LyraT-Mini V1.2运行起来都不正常,没有效果,这是为什么呢?有遇到一样问题的吗?

我用的IDF版本是V4.4,发现algorithm例程中不管用哪个开发板都会把算法输入流类型改为type2:
algorithm_stream_cfg_t algo_config = ALGORITHM_STREAM_CFG_DEFAULT();
#if defined CONFIG_ESP_LYRAT_MINI_V1_1_BOARD
algo_config.input_type = ALGORITHM_STREAM_INPUT_TYPE1;
#elif defined CONFIG_ESP_LYRAT_V4_3_BOARD
algo_config.input_type = ALGORITHM_STREAM_INPUT_TYPE2;
#else
ESP_LOGE(TAG, "[ * ] Do not support current board");
return;
#endif
algo_config.input_type = ALGORITHM_STREAM_INPUT_TYPE2;
element_algo = algo_stream_init(&algo_config);

我用的是LYRAT_MINI板子,算法输入流类型改为type1后,发现保存的录音只有播放的音乐声,没有人声,正常应该是没有音乐声只有人声的,十分疑惑

请按照上面的修改,测试下效果,谢谢。
