I just completed a small theremin project. I now have it built using prototype materials. It runs on 5v. When i first finished it, i was low on time and i used a mini amp to connect to for an audio signal which i then connected to an ipad sound visualizer. So i converted to sound to visual. This was a hassle, and it was weak. I now want to directly connect the electrical output to my computer. I'm considering purchasing an interface, possible this: http://www.behringer.com/EN/Products/302USB.aspx.
This way i can take a guitar input cable and directly connect it. Then i can run that to my mac and use audacity to visualize my theremin sine waves. I'm skeptical about this method and i want to make sure it will work before i purchase my mixer. Another doubt i had was power. I don't want to connect my theremin to 15 volts of electricity. I don't know how these mixers work so any clarification to address my concern will be appreciated.
