Adaptation of Sethares' dissonance measurement function to Python

Example is meant to match the curve in Figure 3:

Original model used products of the two amplitudes a1⋅a2, but this was changed to minimum of the two amplitudes min(a1, a2), as explained in G: Analysis of the Time Domain Model appendix of Tuning, Timbre, Spectrum, Scale.

This weighting is incorporated into the dissonance model (E.2) by assuming that the roughness is proportional to the loudness of the beating. ... Thus, the amplitude of the beating is given by the minimum of the two amplitudes.

How to handle asymmetry of WAV data?

WAV files can store PCM audio (WAVE_FORMAT_PCM). The WAV file format specification says:

The data format and maximum and minimums values for PCM waveform samples of various sizes are as follows:

Sample Size	Data Format	Maximum Value	Minimum Value
One to eight bits	Unsigned integer	255 (0xFF)	0
Nine or more bits	Signed integer i	Largest positive value of i	Most negative value of i

; c1 = ignore the case that was typed, always use the same case for output

This is a Python script to extract GNOME/GTK's color scheme and apply it to Wine, so that the themes (approximately) match.

Instructions:
1. Set your Gnome theme as you would like it
2. Run with a command like "python wine_colors_from_gtk.py"
3. Restart any apps running in Wine.  They should match the Gnome theme colors now.

Measure the distance between two microphones based on the delay of a
clap from a point that is collinear with the two microphones.

Make sure your signal isn't clipping.

First test:
2 electrets 26 cm apart, hand clap
Distance:            -25.72 cm
Sub-sample distance: -26.02 cm
