Raspberry Pi sensing audio? Answered
Hi all --
I have been programming all kinds of things all my life, but I have never had a chance to build a program that responds to audio input. Suddenly: Dancing Baby Groot. I have a great idea for an algorithm for making a very clever and funky Dancing Baby Groot using Raspberry Pi or Arduino -- if I can figure out how to get the processor to "listen" to audio input.
How would I get one of those processors (or any processor) to "listen" to the mic and translate it into either digital or analog data which one could then plunder to figure out the tempo and beat in order to get Baby Groot to Dance? I am 100% sure I can do the plundering (because it works on digital files) if I can get the processor to "listen" to the mic and create a file of numbers which represent the music being played.
