+# ESP32-audioI2S, better WiFi speed
+with a high bit rate or low compression rate, the data throughput via WiFi may not be sufficient to fill the audio buffer sufficiently. In this case, the message 'slow stream, dropouts are possible' appears periodically. Better TCP settings can help. This can be achieved via menuconfig followed by Arduino compilation.
+Here is a complete example that can be easily copy that into PlatformIO.
+
+
+````c++
+#include <Arduino.h>
+#include "WiFiMulti.h"
+#include "Audio.h"
+
+Audio audio;
+WiFiMulti wifiMulti;
+
+String ssid =     "xxxx";
+String password = "xxxx";
+
+#define I2S_LRC     26
+#define I2S_DOUT    25
+#define I2S_BCLK    27
+#define I2S_MCLK     0
+
+void setup() {
+    Serial.begin(115200);
+    wifiMulti.addAP(ssid.c_str(), password.c_str());
+    wifiMulti.run();
+    audio.setPinout(I2S_BCLK, I2S_LRC, I2S_DOUT, -1, -1);
+    audio.setVolume(20); // 0...21
+    audio.connecttohost("http://us3.internet-radio.com:8342/stream");
+}
+
+void loop(){
+    audio.loop();
+}
+
+// optional
+void audio_info(const char *info){
+    Serial.print("info        "); Serial.println(info);
+}
+
+
+````
+
+
+
+These are the main settings:

+
+This directory is intended for project header files.
+
+A header file is a file containing C declarations and macro definitions
+to be shared between several project source files. You request the use of a
+header file in your project source file (C, C++, etc) located in `src` folder
+by including it, with the C preprocessing directive `#include'.
+
+```src/main.c
+
+#include "header.h"
+
+int main (void)
+{
+ ...
+}
+```
+
+Including a header file produces the same results as copying the header file
+into each source file that needs it. Such copying would be time-consuming
+and error-prone. With a header file, the related declarations appear
+in only one place. If they need to be changed, they can be changed in one
+place, and programs that include the header file will automatically use the
+new version when next recompiled. The header file eliminates the labor of
+finding and changing all the copies as well as the risk that a failure to
+find one copy will result in inconsistencies within a program.
+
+In C, the usual convention is to give header files names that end with `.h'.
+It is most portable to use only letters, digits, dashes, and underscores in
+header file names, and at most one dot.
+
+Read more about using header files in official GCC documentation:
+
+* Include Syntax
+* Include Operation
+* Once-Only Headers
+* Computed Includes
