 ## Usage
+### Player
 1. Add the player view in your layout :
 ```
 <fr.haran.soundwave.ui.PlayerView
     android:id="@+id/player_view"
-    android:layout_width="match_parent"
-    android:layout_height="200dp"

 ```

 ```
 view.addAudioUrl(url,amplitudes)
 ```
-Note : you need to add the Internet permission in your manifest
+The amplitudes are an array of double inside [-1.0; 1.0].
 
-For a more detailed use case application, please have a look at the example app in the repository.
+4. Do not forget to destroy the player inside the OnDestroy method of your Activity.
+```
+playerController.destroyPlayer()
+```
+
+### Recorder
+The recorder ressembles to the player a lot but here is a quick tutorial.
+1. Add the recorder view in your layout
+```
+<fr.haran.soundwave.ui.RecPlayerView
+        android:id="@+id/rec_player_view"
+        app:rec_color="@android:color/black"
+        app:rec_playedColor="@android:color/darker_gray" 
+        ... />
+```
+
+2. In your Activity, create a custom controller implementing the RecorderController interface or use the default one (You need to reference the view, and the path where the files will be created) :
+```
+recorderController = DefaultRecorderController(findViewById(R.id.rec_player_view), applicationContext.externalCacheDir?.absolutePath?)
+```
+
+3. Set a listener and prepare the controller
+```
+recorderController.setRecorderListener(validate = {...})
+recorderController.prepareRecorder()
+```
+Using the default listener is perfectly fine but you should at least use the validate function to use the files.
+
+4. Do not forget to destroy the recorder inside the OnDestroy method of your Activity.
+```
+recorderController.destroyPlayer()
+```
+For a more detailed implementation, please have a look at the example app in the repository.
 
 ## Building the amplitudes
 As mentionned before, for now this library does not implement the calculation of the amplitudes so you should implement this by yourself. For my use case, a static array was enough.
+Moreover the formats the recorder and the player uses are different. This will be solved soon.
