I don't have any flipping idea what I am doing, I just want to add some more components to the tubes list!
LiveSPICE is a circuit simulator that attempts to run in real time with minimal latency for audio signals. It processes signals from audio input devices attached to your computer, and plays the results to the speakers.
For more information, see http://www.livespice.org.
The LiveSPICE solution requires the ComputerAlgebra project: https://github.com/dsharlet/ComputerAlgebra
To clone the LiveSPICE repo, run the following commands:
git clone --recursive https://github.com/dsharlet/LiveSPICE.git LiveSPICE
