Error in 1.1.9 Using p5.Amplitude with p5.AudioIn

[lisajamhoury]

I'm using p5.js and p5.sound.js @1.1.9. I am using p5.Amplitude without a problem. When I add a new p5.AudioIn to the sketch to use the microphone I get the following two errors in the console:

You can see the error in this p5 sketch. It works without a problem with 0.9.0. If you update the library in the index to 1.1.9 you will see the error in the console.

Although I didn't get any error what I found out is p5.Amplitude doesn't work as expected if the mic(p5.AudioIn) is running. For that either stop the mic while listening to other sources/soundfiles or use max(amp.getLevel(),mic.getLevel()) . The first one is the logical way , second one is just a workaround
