I have recorded my recordings and it works!
The recordings are still very quiet and I will continue to try and make them louder, but I really think it is just because of the size and power of the speaker.
Here is a video of it working.
Words can't express how happy I am. This long journey is now over. While I am happy it is over, I can't help but feel there is a part of me missing.
Thank you for my professor, Audrey, and all of her help. I wouldn't have been able to make it this far without her.
Thank you to my parents for all of their support. Thank you to my friends and extended family - you didn't know I was doing this...but you still helped me. And thank you to my fans - I love ALL of you.
