+
+2. License Grants and Conditions
+--------------------------------
+
+2.1. Grants
+
+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or
+    as part of a Larger Work; and
+
+(b) under Patent Claims of such Contributor to make, use, sell, offer
+    for sale, have made, import, and otherwise transfer either its
+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+*  statutory, including, without limitation, warranties that the       *
+*  Covered Software is free of defects, merchantable, fit for a        *
+*  particular purpose or non-infringing. The entire risk as to the     *
+*  quality and performance of the Covered Software is with You.        *
+*  Should any Covered Software prove defective in any respect, You     *
+*  (not any Contributor) assume the cost of any necessary servicing,   *
+*  repair, or correction. This disclaimer of warranty constitutes an   *
+*  essential part of this License. No use of any Covered Software is   *
+*  authorized under this License except under this disclaimer.         *
+*                                                                      *

+
+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the
+courts of a jurisdiction where the defendant maintains its principal
+place of business and such litigation shall be governed by laws of that
+jurisdiction, without reference to its conflict-of-law provisions.
+Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License
+---------------------------
+
+10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section
+10.3, no one other than the license steward has the right to modify or
+publish new versions of this License. Each version will be given a
+distinguishing version number.
+
+10.2. Effect of New Versions
+
+You may distribute the Covered Software under the terms of the version
+of the License under which You originally received the Covered Software,
+or under the terms of any subsequent version published by the license
+steward.
+
+10.3. Modified Versions
+
+If you create software not governed by this License, and you want to
+create a new license for such software, you may create and use a
+modified version of this License if you rename the license and remove
+any references to the name of the license steward (except to note that
+such modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary
+Licenses

-[right][tutorial[000_Build | Next: Tutorals]][/right]
-
-=== Overview:===
-
-===User requires:===
-To use ewol you need to know only C++ language. It could be usefull to know:
-:** [b]Python[/b] for all build tool.
-:** [b]git[/b] for all version management
-:** [b]Audio[/b] Basic knowlege of audio streaming af data organisation.
-
-=== Architecture:===
-River has been designed to replace the pulseAudio basic asyncronous interface that create 
-more problem that it will solve. The second point is that is not enougth portable to be 
-embended in a proprietary software without distributing all the sources (Ios).
-
-Start at this point we will have simple objectives :
-:** manage multiple Low level interface: (done by the [lib[airtaudio | AirTAudio]] interface):
-::** for linux
-:::** Alsa
-:::** Pulse
-:::** Oss
-::** for Mac-OsX
-:::** CoreAudio
-::** for IOs
-:::** CoreAudio (embended version)
-::** for Windows
-:::** ASIO
-::** For Android
-:::** Java (JDK-6)
-:** Synchronous interface ==> no delay and reduce latency
-:** Manage the thread priority (need sometimes to be more reactive)
-:** manage mixing of some flow (2 inputs stereo and the user want 1 input quad)
-:** AEC Acoustic Echo Cancelation (TODO : in the current implementation we have a simple sound cutter)
-:** Equalizer (done with [lib[drain | Drain])
-:** Resmpling (done by the libspeexDSP)
-:** Correct volume management (and configurable)
-:** Fade-in and Fade-out (done with [lib[drain | Drain])
-:** Channel reorganisation (done with [lib[drain | Drain])
-:** A correct feedback interface

+========================
+
+@tableofcontents
+
+Objectifs:                                         {#audio_river_config_file_objectif}
+==========
+
+  - Understand the architecture of the configuration file.
+  - all that can be done with it.
+
+
+Basis:                                             {#audio_river_config_file_bases}
+======
+
+The river configuration file is a json file. We use @ref ejson_mainpage_what to parse it then we have some writing facilities.
+
+
+River provide a list a harware interface and virtual interface.
+
+
+The hardware interface are provided by @ref audio_orchestra_mainpage_what then we will plug on every platform.
+
+
+The file is simply architecture around a list of object:
+
+```{.json}
+{
+	"speaker":{
+		
+	},
+	"microphone":{
+		
+	},
+	"mixed-in-out":{
+		
+	},
+}
+```
+
+With this config we declare 3 interfaces : speaker, microphone and mixed-in-out.
+
+
+Harware configuration:                             {#audio_river_config_file_hw_config}
+======================
+
+In every interface we need to define some Element:
+  - "io" : Can be input/output/... depending of virtual interface...
+  - "map-on": An object to configure airtaudio interface.
+  - "frequency": 0 to automatic select one. Or the frequency to open harware device
+  - "channel-map": List of all channel in the stream:
+      * "front-left"
+      * "front-center"
+      * "front-right"
+      * "rear-left"
+      * "rear-center"
+      * "rear-right"
+      * "surround-left",
+      * "surround-right",
+      * "sub-woofer",
+      * "lfe"
+  - "type": Fomat to open the stream:
+      * "auto": Detect the best type
+      * "int8",
+      * "int8-on-int16",
+      * "int16",
+      * "int16-on-int32",
+      * "int24",
+      * "int32",
+      * "int32-on-int64",
+      * "int64",
+      * "float",
+      * "double"
+  - "nb-chunk": Number of chunk to open the stream.
+
+
+Generic configuration file use
+==============================
+
+You can specify a generic configuration file foir a user in the path ```~/.local/share/audio-river/config.json```
+
+The default config file is:
+
+```{.json}
+{
+	microphone:{
+		io:"input",
+		map-on:{
+			interface:"auto",
+			name:"default",
+		},
+		frequency:0,
+		channel-map:[
+			"front-left", "front-right"
+		],
+		type:"auto",
+		nb-chunk:1024,
+		mux-demux-type:"float"
+	},
+	speaker:{
+		io:"output",
+		map-on:{
+			interface:"alsa",
+			name:"default",
+		},
+		frequency:0,
+		channel-map:[
+			"front-left", "front-right",
+		],
+		type:"auto",
+		nb-chunk:1024,
+		volume-name:"MASTER",
+		mux-demux-type:"float"

-== Why we use "DECLARE_FACTORY" Macro ? ==
-
-For some reason!!! But everything might be clear:
-:** In ewol we masively use std::shared_ptr<xxx> (I have create my own but it is not "standard" (I like when we use genecic system)).
-:** The main class : [class[ewol::Object]] herited from [i]std::enable_shared_from_this<Object>[/i] to permit to access at his own [i]std::shared_ptr[/i].
-:** Acces At his own [i]std::shared_ptr[/i] is not allowed in the class contructor/destructor.
-:** Many time for meta-widget we need to propagate our [i]std::shared_ptr[/i] in child.
-
-Then for all these reasons, I have create a simple MACRO that create a static template funtion that create the object and just after 
-creation call the init(...) function to permit to create a complex widget or others with some writing convinience.

-it is designed to be multi-platform and is based on licence that permit to integrate it
-on every program we want.
-
-===Where can I use it?===
-Everywhere! RIVER is cross-platform devolopped to support bases OS:
-: ** Linux (over Alsa, Pulseaudio, JackD)
-: ** Windows (over ASIO)
-: ** MacOs (over CoreAudio)
-: ** Android (Over Ewol wrapper little complicated need to be change later)
-: ** IOs (over CoreAudio for ios)
-
-===What languages are supported?===
-RIVER is written in C++11 with posibilities to compile it with C++03 + Boost
-
-===Are there any licensing restrictions?===
-RIVER is [b]FREE software[/b] and [i]all sub-library are FREE and staticly linkable !!![/i]
-
-That allow you to use it for every program you want, including those developing proprietary software, without any license fees or royalties.
-
-[note]The static support is important for some platform like IOs, and this limit the external library use at some license like :

+: ** IOs (over CoreAudio for ios)
+
+AUDIO-RIVER is dependent of the STL (compatible with MacOs stl (CXX))
+
+Architecture:
+-------------
+
+River has been designed to replace the pulseAudio basic asyncronous interface that create
+more problem that it will solve. The second point is that is not enougth portable to be
+embended in a proprietary software without distributing all the sources (Ios).
+
+Start at this point we will have simple objectives :
+  - Manage multiple Low level interface: @ref audio_orchestra_mainpage_what
+     * for linux (Alsa, Pulse, Oss)
+     * for Mac-OsX (CoreAudio)
+     * for IOs (coreAudio (embended version))
+     * for Windows (ASIO)
+     * For Android (Java (JDK...))
+  - Synchronous interface ==> no delay and reduce latency
+  - Manage the thread priority (need sometimes to be more reactive)
+  - manage mixing of some flow (2 inputs stereo and the user want 1 input quad)
+  - AEC Acoustic Echo Cancelation (TODO : in the current implementation we have a simple sound cutter)
+  - Equalizer (done with @ref audio_drain_mainpage_what)
+  - Resmpling (done by the libspeexDSP)
+  - Correct volume management (and configurable)
+  - Fade-in and Fade-out @ref audio_drain_mainpage_what
+  - Channel reorganisation @ref audio_drain_mainpage_what
+  - A correct feedback interface
+

+Objectifs:                                          {#audio_river_read_objectif}
+==========
+
+  - Understand basis of river
+  - Create a simple recording interface that print the average of sample absolute value.
+
+
+When you will create an application based on the river audio interface you need :
+
+Include:                                            {#audio_river_read_include}
+========
+
+Include manager and interface node
+@snippet read.cpp audio_river_sample_include
+
+Initilize the River library:                        {#audio_river_read_init}
+============================
+
+We first need to initialize etk sub library (needed to select the log level of sub-libraries and file access abstraction
+@snippet read.cpp audio_river_sample_init
+
+Now we will initilaize the river library.
+To do this We have 2 posibilities:
+With a file:
+------------
+
+```{.cpp}
+	// initialize river interface
+	river::init("DATA:///configFileName.json");
+```
+
+With a json string:
+-------------------
+
+@snippet read.cpp audio_river_sample_read_config_file
+
+```{.cpp}
+// initialize river interface
+river::initString(configurationRiver);
+```
+
+For the example we select the second solution (faster to implement example and resource at the same position.
+
+river::init / river::initString must be called only one time for all the application, this represent the hardware configuration.
+It is NOT dynamic
+
+To understand the configuration file Please see @ref audio_river_config_file
+
+This json is parsed by the @ref {#ejson_mainpage_what} it contain some update like:
+  - Optionnal " in the name of element.
+  - The possibilities to remplace " with '.
+
+
+
+Get the river interface manager:                        {#audio_river_read_river_interface}
+================================
+
+An application can have many interface and only one Manager. And a process can contain many application.
+
+Then, we will get the first application manager handle.
+@snippet read.cpp audio_river_sample_get_interface
+
+*Note:* You can get back the application handle when you create a new one with the same name.
+
+Create your read interface:                            {#audio_river_read_river_read_interface}
+===========================
+
+Generic code:
+@snippet read.cpp audio_river_sample_create_read_interface
+
+Here we create an interface with:
+  - The frequency of 48000 Hz.
+  - The default Low level definition channel
+  - A data interface of 16 bits samples coded in [-32768..32767]
+  - Select input interaface name "microphone"
+
+
+set data callback:                                     {#audio_river_read_get_data}
+==================
+
+The best way to get data is to instanciate a simple callback. 
+The callback is called when sample arrive and you have the nbChunk/frequency
+to process the data, otherwise you can generate error in data stream.
+
+@snippet read.cpp audio_river_sample_set_callback
+
+Callback inplementation:                               {#audio_river_read_callback}
+========================
+
+Simply declare your function and do what you want inside.
+
+@snippet read.cpp audio_river_sample_callback_implement
+
+start and stop the stream:                             {#audio_river_read_start_stop}
+==========================
+
+@snippet read.cpp audio_river_sample_read_start_stop
+
+Remove interfaces:                                     {#audio_river_read_reset}
+==================
+
+@snippet read.cpp audio_river_sample_read_reset
