+# Webserver
+
+With the help of the ESP32 WIFI functionality we can implement a simple web server. 
+In the example we use a Sine Wave generator as sound source and return the result as an WAV file
+
+The server can be used like any other output stream and we can use a StreamCopy to provide it with data.
+
+Multiple users can connect to the server!
