Tempo Tracking and More Searching

with No Comments

Yesterday, as suggested by Forrest, I added the ability to calculate the current tempo of the music in BPM based on the amount of time in between the last two detected beats. It doesn’t attempt to ignore any false positive readings, and it doesn’t take into account the time taken up by the sleep function, but it’s a rough solution for now.

Now, the next major step I am hoping to take with this program is to use the beats to play some notes through MIDI messages. I am searching for libraries that will allow me to send MIDI note on/off messages to some basic synthesizer, and FluidSynth looks to be a decent option so far.
