resonance-finder

A tool to help you find the resonance of objects in your room. Make sure you have a subwoofer.

Setup

You need to install the Wavebender library before doing anything.

Playing the resonant frequency of an object is simple with these 3 steps:

Find when the sweeper reaches resonance. Run python sweeper.py | aplay and a stopwatch simultaneously. When you reach resonance, record the time on your stopwatch.
Get the resonant frequency from this time. Use the command python get_frequency.py 3.4 replacing 3.4 with the number of seconds elapsed (the time you recorded on the stopwatch).
Play the frequency. Use python play_wave.py 100.0 | aplay where 100.0 is instead the frequency from get_frequency.py in Hz.

Now you can troll people by shaking their desks/room/anything!
