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...

dedicated hardware for handling audio signals more efficiently form the start, rather than requiring you to add components later. These boards often feature analog-to-digital (AD) and digital-to-analog (DA) converters that allow them to seamlessly convert between analog audio inputs and digital ...
(supports up to 3 meter sensitivity when playing music), DSP chip for handling the 4-mic array input, phone jack, left & right speaker output ports, audio driver chip, DC/DC boost power supply, power switch, battery connector, USB power input port, USB connectivity port, UART headers, ...
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 ...
