FFT SPIRAL PLOTS

These spectral plots are realized in mixture of Audacity for fft data, Python and Processing. The brightness of the image reflects the overall power of the recording. The color-scale goes from minimum: red, over yellow, green, blue to maximum: pink. Octave harmonics lie on a straight line from the center and out. The maximum frequency represented is 96khz.
