Hello,
I'm looking for a circuit where I can record audio like the sound of a train engine. Then I would like to play the audio back and as the voltage on the tracks increases the speed of the sound increases. I have been trying to look for a circuit and I can't seem to find one. I have experience with electronics so don't hold back on the complexity of the circuit. I know I can buy sound modules already made but I don't want to spend $150 on it when I can make one. Your help would be appreciated. Thanks
Ryan
