## Description
|
||
|
||
**Node**, like its namesake, is a smart node with full-featured functions in a IoT application scenarios. Together with M5Stack Core, it can be programmed as an intelligent speaker like Echo. Node provides more hardware resources: built-in high-fidelity audio codec chip，MIC, DHT12, IR
|
||
|
||
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, TF-card(microSD), 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.
|
||
