from enviroplus.noise import Noise

print("""noise-profile.py - Get a simple noise profile.

This example grabs a basic 3-bin noise profile of low, medium and high frequency noise, plotting the noise characteristics as coloured bars.

print("""noise-amps-at-freqs.py - Measure amplitude from specific frequency bins

This example retrieves the median amplitude from 3 user-specified frequency ranges and plots them in Blue, Green and Red on the Enviro+ display.

As you play a continuous rising tone on your phone, you should notice peaks that correspond to the frequency entering each range.
