1. Audio Signal Flow By Jodi Kidneigh Week 1 IMPMOOC

2. Introduction Hi I’m Jodi Kidneigh, and I live in Orlando, FL in the United States. Welcome to my lesson in Audio Signal Flow. This lesson is for week 1 of Introduction To Music Production at Coursera.org. I will be explaining a basic condenser microphone recording signal flow using the gear in my home studio which I like to call “Frog Song Studios”.

15. Reflections and Thanks Thank you for taking the time to review my lesson in Audio Signal Flow. I chose this topic to gain a deeper understanding of the equipment I’m using because I realize that I am not utilizing the full capabilities of my home studio setup. Any advice or techniques you wish to share are welcome and appreciated!
