Get byte data from swf


I came across a tutorial online which was demonstrating how to dynamically generate sound.

Conceptually I think I know what is going on but I’m stuck on one of the steps.

In step 2 it says

“Copy & paste the entire data from the .swf into an array in my AS3 project”

Below is an example of what the data should look like

0x46, 0x57, 0x53, 0x08, 0x4b, 0x2b, 0x00, 0x00, 0x78, 0x00, 0x05,

Would anyone know how to “copy” the entire data?
