Resources and Going Further
This project is meant to be hacked! Try changing some of the variables in the Parameters section of the code to see if you can get the voice to sound the way you want. You can also import the block diagram into the Audio System Design Tool by copying in everything before the // GUItool: end automatically generated code line and clicking Import in the Audio System Design Tool. Add some new blocks and really distort your voice!
Here's an example of the project wired into a Scout Trooper helmet:
