I’m doing some work with Minim and I found a few samples for visualizing waveforms that are using arraycopy. The samples seem to work as expected in the code, except I’m getting warnings that the method is deprecated. `the method arraycopy(object object) from the type PApplet is deprecated`. Code sample was from this post: [https://forum.processing.org/one/topic/how-to-generate-a-simple-waveform-of-an-entire-sound-file.html](https://forum.processing.org/one/topic/how-to-generate-a-simple-waveform-of-an-entire-sound-file.html)
Is there another method I should be using instead of arraycopy? Should I update it or just let the warning run and just ignore it?
Thanks.

Yes, use **arrayCopy()** in place of **arraycopy()**, even though they’re exactly the same thing: 🤪

Thanks, should have noticed that! 🙃
