+AUDIO-ESS library                                {#mainpage}
+=================
+
+@tableofcontents
+
+What is AUDIO-ESS:                               {#audio_ess_mainpage_what}
+==================
+
+AUDIO-ESS, or Ewol Sound Set interface is designed to be a 'small game' audio effects engine. 
+==> fast to generate sound without attention at how thay are play and do not pay attention at the stop.
+
+
+What it does:                               {#audio_ess_mainpage_what_it_does}
+=============
+
+  - Load ogg/wav efffects and stay ready to play it
+  - play file without latency
+  - Manage a basic soundset
+
+AUDIO-ESS is dependent of the STL (compatible with MacOs stl (CXX))
+
+What languages are supported?                    {#audio_ess_mainpage_language}
+=============================
+
+AUDIO-ESS is written in C++.
+
+
+Are there any licensing restrictions?            {#audio_ess_mainpage_license_restriction}
+=====================================
+
+AUDIO-ESS is **FREE software** and _all sub-library are FREE and staticly linkable !!!_

+Tutoral: use sound-set                              {#audio_ess_tuto}
+======================
+
+@tableofcontents
+
+Objectifs:                                          {#audio_ess_tuto_objectif}
+==========
+
+  - Understand config file
+  - Create a simple playing sounds
+
+Create a configuration file                         {#audio_ess_tuto_config_file}
+===========================
+
+configuration file is really simple:
+```{.sh}
+soundSet.json
+```
+it contain 2 mains object:
+  - **musics:** That containig the list of all music files
+  - **effects:** That contain all effects files
+
+A simple example:
+```{.json}
+{
+	musics:{
+		"BG-1":"DATA:audio/Clean Soul.ogg"
+		"BG-22":"DATA:audio/Dark knight.ogg"
+	},
+	effects:{
+		"end":"DATA:audio/end.wav",
+		"error":"DATA:audio/error.wav",
+		"levelup":"DATA:audio/levelup.wav",
+		"ok":"DATA:audio/ok.wav"
+	}
+}
+```
+
+what you need to do first:                          {#audio_ess_tuto_include}
+==========================
+
+Include and basic init:
+```{.cpp}
+#include <audio/ess/ess.h>
+
+//in the main application:
+int main(...) {
+	audio::ess::init();
+	/*
+	 * Do your stuff
+	 */
+	audio::ess::unInit();
+	return 0;
+}
+
+```
+
+Select your sound set file:
+```{.cpp}
+	audio::ess::soundSetLoad("DATA:soundSet.json");
+```
+
+Play a background music:                            {#audio_ess_tuto_play_music}
+========================
+
+Start playing:
+```{.cpp}
+	audio::ess::musicPlay("BG-22");
+```
+
+Stop playing:
+```{.cpp}
+	audio::ess::musicStop();
+```
+
+Change volume: (reduce at -5dB)
+```{.cpp}
+	audio::ess::musicSetVolume(-5.0f);
+```
+
+Play an effect:                                     {#audio_ess_tuto_play_effect}
+===============
+
+Start playing:
+```{.cpp}
+	audio::ess::effectPlay("error");
+	sleep(1);
+	audio::ess::effectPlay("levelup");
+```
+
+or (faster way):
+```{.cpp}
+	int32_t effectId = audio::ess::effectGetId("error");
+	audio::ess::effectPlay(effectId);
+```
+**Note:** An effect can not stopped ...
+
+Change volume: (reduce at -5dB)
+```{.cpp}
+	audio::ess::effectSetVolume(-5.0f);
+```
