exporting a processing sketch that uses microphone input to webpage - processing

Question

i'm trying to get my processing sketch to work online with processing.js. It work fine when i just use a very simple processing sketch but when i try to uploade my actual code to the server it does not work
I know my code is pretty messy and stuff but i don't have time to clean up right now i just want it to show in a browser
here is my code :
`

Answer 1

That's because minim (and most Processing libraries) are made in Java. When you are in "Java mode" your sketch is also in Java. When though you go to "Javascript mode" and you upload to server, your sketch is translated to javascript (a different language) but your library is not, thus it can not run. Your best bet is probably to find a way to embed your sketch as a Java applet!
