Summary[edit]

Spectrum analysis of the uncompressed source for 5 seconds of triangle wave at 1000 Hz. Note the logarithmic frequency scale. The y-range of this graph may not be appropriate for comparison of similar waveforms; it is designed to match the frequency spectrum graphs for audio noises on en:Colors of noise.

The analysis was done using en:Audacity, and plotting with en:gnuplot. Transparency was touched up in en:GIMP to make the graph background pure white.

Instructions[edit]

Obtain the frequency analysis from Audacity, set the maximum number of windows, and use a Hamming window. The following script was used to generate the image:

 
This plot was created with Gnuplot.
