Hello,
please help me, Im writing an app for my schoolarship.
I want to do a fuzz and a overdrive. I created a switch, which picks the right fucntion and with an aplly button, matlab should run the function and read it in as an audio, with audiorecorder.
The funtion are working fine, if im not in app designer.

The first argument in a method (that's what functions are called in object oriented programming) of an object is the object instace (i.e self in Java or this in .Net)
Writing
app.fuzz(x)
Invokes the fuzz function the same as this line would:
fuzz(app, x)
So you actually need to have two arguments in that method, where the first one is app
Java and .Net sugar-coat it and hide the passing of instance arguments behind the scenes but Matlab doesn't. It takes some getting used to, but it makes sense

The app.audioin1 is the overdone audio, the input is the first audio data I recorded and read it in with uigetfile.
This file was read in in fuzz and then i want to make an audiofile of it using audiorecorder.
I dont understand what you mean with instance.
Do you think i have to make an extra fuzz output wich is only data and then read it into audiorecorder? thats what i tried to do.

An instance is a unit of some class.
When you careated the audiorecorder you got an instance of that class.
I think your best option is to save it as a property of your app
