The Audio Signal Routers cell includes 2 different versions. 
  - Audio Signal Router
  - Audio Signal Router External Index Selectable 

===== Audio Signal Router =====
{{ :resources:tools-software:sigmastudio:toolbox:mixerssplitters:audiosignalrouter.png?nolink |}}
Audio Signal router mixes M different inputs to N different outputs with various gains. The number of input and output pins are configurable. 
{{ :resources:tools-software:sigmastudio:toolbox:mixerssplitters:audiosignalroutergrow.jpg?nolink |}}

This module supports multiple mixer configurations. Each mixer configuration has gains for all the inputs and outputs.  A separate gain is available for each of input output combination also. All the gains has a corresponding mute control to quickly mute the particular gain. The current Tab selected (Mix #) in the mixer window is downloaded to the target and used for mixing.

The following equations show the  calculation of the output for given sample mixer table. 
|        ^       ^ <fc #0000FF>Out0</fc>   ^ <fc #0000FF>Out1</fc>  ^
^        |       | //Og0//                     | //Og1//                    |
^ <fc #008000>In0</fc>    | //Ig0//   | G00    | G01   |
^ <fc #008000>In1</fc>    | //Ig1//   | G10    | G11   |



    - <fc #0000FF>Out0</fc> = //Og0// * ( G00 * //Ig0// * <fc #008000>In0</fc> + G10 * //Ig1// * <fc #008000>In1</fc>)
    - <fc #0000FF>Out1</fc> = //Og1// * ( G01 * //Ig0// * <fc #008000>In0</fc> + G11 * //Ig1// * <fc #008000>In1</fc>)

If the input/output channels are more than 16, then the mixer window is split for 16 input/output channels to improve GUI performance.

Labels for each of the input/output channels can be edited. This updated channel name will pear on the each of the Pin's tooltip as show below.

===== Audio Signal Router External Index Selectable =====
This functionality of this module is same as audio signal router except that the current mixer (Mix #) is selected through an external input as shown below. The control pin expects the input in (32.0) format for ADAU145x processors and (28.0) format for other Sigma DSPs.

===== Audio Signal Router Script support =====
User can able to access this module from script.

The following sample code shows how to read parameters from a file using Sigma studio script. 
<code csharp>
// #LANGUAGE# C#
// Get Cell object

object obj = ss.GetCellObject("Router1");
System.Collections.ArrayList arr = null;
System.Reflection.MethodInfo[] memberInfos = ss.ObjectGetMethods(obj);
/*foreach (System.Reflection.MethodInfo memberInfo in memberInfos) 
{	
   ss.PrintLine(memberInfo.Name);
}*/

//OPEN the SETTINGWINDOW
System.Reflection.MethodInfo methodInfo = ss.ObjectGetMethod(obj, "settingswindowopen");
ss.PrintLine(methodInfo.Name);
methodInfo.Invoke(obj, new object[]{});

//CHANGE the Table INDEX
//and set the values
// chage the tabindex count based on need and will get the tabindex value.which is used here.
//setTabIndex should be 0 to 3.
for (int idx =0; idx <= 1; idx++)
{
System.Reflection.MethodInfo methodInfo1 = ss.ObjectGetMethod(obj, "setTabIndex");
ss.PrintLine(methodInfo1.Name);
methodInfo1.Invoke(obj, new object[]{idx,2});
ss.ObjectSetProperties("setControlValue", "Router1", 0, 0, "InputGain_0" , 6.0);
ss.ObjectSetProperties("setControlValue", "Router1", 0, 0, "InputGain_10" , 2);
ss.ObjectSetProperties("setControlValue", "Router1", 0, 0, "InputGain_12" , 3);
ss.ObjectSetProperties("setControlValue", "Router1", 0, 0, "OutputGain_10" , 0.3);
ss.ObjectSetProperties("setControlValue", "Router1", 0, 0, "OutputGain_12" , 0.3);
ss.ObjectSetProperties("setControlValue", "Router1", 0, 0, "OutputGain_9" , 0.3);
ss.ObjectSetProperties("setControlValue", "Router1", 0, 0, "CrossGain_0_1" , 0.5);
ss.ObjectSetProperties("setControlValue", "Router1", 0, 0, "CrossGain_0_0" ,0.6);
}


//CLOSE the SETTINGWINDOW
System.Reflection.MethodInfo methodInfo2 = ss.ObjectGetMethod(obj, "settingswindowclose");
ss.PrintLine(methodInfo2.Name);
methodInfo2.Invoke(obj, new object[]{});
