Popis:
Spectrum analysis of uncompressed source for 10 seconds of white noise. Note the logarithmic frequency scale.
The analysis was done using Audacity, and plotting with gnuplot. Transparency was touched up in GIMP to make the graph background pure white.
(I find the log frequency plot here confusing, as it suggests that white noise may rise slightly with increasing frequency. A linear frequency scale would be better. However, for comparison with pink noise, having the log frequency plot keeps the frequency axis on both the same.)
