This is how you would implement a function inside an interface:

For example, create a custom screen named "audioPlayer" and in the audioPlayer.xml file add:

<interface>
    <function name="doSomething" />
</interface>

In the audioPlayer.brs file declare "doSomething" function:

Function doSomething(param as String)
    print param
End Function

Now in your HomeScene.xml add this custom created "audioPlayer" screen/component and in HomeScene.brs init() function add:

m.audioPlayer = m.top.findNode("audioPlayer")

You can call your doSomething() function from HomeSceene.brs with this peace of code:

param = "Do Androids Dream of Electric Sheep?"
m.audioPlayer.callFunc("doSomething",param)
