How to get Flash to use more memory/hardware

Hi I use a browser app called ''AudioTool'' which allows me to create music in browser.

Over the past few months of using it my songs have become complex and heavy and now most of them have loads of lag or crashes.
This is very annoying for me as I can no longer continue my work

It says either the Flash has crashed or the shockwave has crashed

I contacted the developer and they told me I was hitting the flash players memory limit, it quickly used 2gb then stopped loading.
I have a fast machine with 16gb of ram.. How do I allocate this browser/flash to use more of this ram to stop the crashes?

Thanks!
