Description:
Node, like its namesake, is a smart node with full-featured functions in a IoT application scenarios. It can be program as a intelligent speaker like Echo. Node provides more hardware resources: built-in high-fidelity audio codec chip,MIC, DHT12, IR emitter ...
ESP32 provides an Audio Develope Platform called ESP-ADF. ESP-ADF supports development of audio applications for the Espressif Systems ESP32 chip in the most comprehensive way. With ESP-ADF, you can easily add features, develop audio applications from simple to complex:
- Music player or recorder supports audio formats such as MP3, AAC, FLAC, WAV, OGG, AMR, TS, EQ, Downmixer, Sonic, G.711, SPEEX ...
- Play music from sources: HTTP, HLS(HTTP Live Streaming), SPIFFS, SDCARD, A2DP-Source, A2DP-Sink, HFP ...
- Integrate Media services such as: DLNA, WeChat ... Internet Radio
- Voice recognition and integration with online services such as Alexa, DuerOS, and more.
