使用的是esp_dispatcher_dueros_app初始化的audio,初始化函数是setup_player。 使用esp_audio_play播放声音时,用esp_audio_state_get获取播放状态,如果播放源是http,可以获得正确状态;如果播放源是sdcard文件,获取到状态是AUDIO_STATUS_UNKNOWN。 看了一下setup_player,通过函数esp_audio_input_stream_add添加了两个...

River and stream data, for example, needs to cut appropriately into the terrain in order to flow correctly downhill to the sea. There are three main tools that come with this SDK. The Resample tool can replace existing source data with new data, or add photo-imagery to specific locations ...
Additionally, it supports a 3.7V lithium battery input and 5V 2A power input, with simultaneous lithium battery charging capability. **Advanced Features and Connectivity** The ESP32-Audio-Kit is not just about audio; it's a powerhouse of connectivity. It supports interfaces such as UART/SPI/...
