Finite Observation intervals

Choose a signal (sinusoid, white/coloured noise, or speech), adjust the observation length, and compare real measurements against the theoretical autocorrelation and power spectral density.

Compact controls
Speech-friendly option
Controls above plots

Controls stay pinned above the plots. Ideal mode falls back to a real measurement for the speech option.
