Detect beat and play (wav) file in a synchronised manner

Question

I am trying my hands at Audio Processing in python with this Beat Detection algorithm. I have implemented the first (non-optimized version) from the aforementioned article.

Answer 1

A good bet would be to try portaudio (pyaudio) to get the data live, then you should be able to see if it matches.

Here's a nice example using fft from the mic with pyaudio:
