* @brief A simple WebSocket client sketch that sends out some PCM audio
|
|
* data using the https://github.com/Links2004/arduinoWebSockets library.AdapterAudioStreamToAudioOutput.AdapterAudioStreamToAudioOutput
|
|
* The WebSocket API is asynchronous, so we need to slow down the sending
|
|
* to the playback speed, to prevent any buffer overflows at the receiver.
