Too much gain on lower end Frequency

[Blauenfeldt]

Whenever i play a song, and there is some low end frequencies, 0-200 Hz, all of the visualization action gets cramped down the that area, and none of the other frequencies, ~200-8000 Hz, will be lit up.

Is there a way to turn down the gain at those frequencies?

Raspberry Pi 3 b
Settings:
N_Pixels = 88
Min Freq = 20
Max Freq = 8000
N FFT BINS = 14
Min Volume Threshold = 1e-4

Edit: I partially found a fix. At line 220 in visualization.py, I sat mel_gain.update(np.max(gaussian_filter1d(mel, sigma=1.0))) to mel_gain.update(np.max(gaussian_filter1d(mel, sigma=25.0))). Now I see more LEDs being lit, instead of the 10%, but with the cost of oversaturated colors in the middle of the strip.
