Hello,

im am writing a little App. It is a project for my schoolarship.

I want to create an rocker switch, which can create the fuzz sound and an overdrive sound.

But everytime i try to do it, it doesent work. Matlab brings always the same error. I have tried anonymous function, setting only a var for the val, create abs as a own function in my app and so....

Please someone helps me... I m really frustrated...

You're trying to call abs on the audioin property of your app, which is not a number but some sort of audio importing object. Try importing the audio data from that object then call abs on that data rather than the object.
