CochSim is a dynamic simulation of the time and frequency analysis performed by the ear.
Sound signals such as sinewaves, pulse trains, sawtooth waves and vowels can be fed into an
auditory filterbank and the output monitored in a moving animated display. The program shows the
vibration of the oval window and the basilar membrane, the haircell activity against filter
frequency and time, and an average excitation pattern across the cochlea.
ESection is a free program for calculating and displaying spectral and other related analyses of sections of a speech signal. It can be used to demonstrate the different spectral properties of elements of speech. It can also calculate an LPC spectrum, autocorrelation and cepstrum analyses, and can display the signal as a waveform or as a spectrogram. It automatically finds formant and fundamental frequency values.
A tutorial that provides an elementary introduction to the mathematics of Logarithms.
FAROSON is a free program for displaying a real-time scrolling coloured pattern from speech sounds. The aim is to construct a pattern that reflects our subjective sensations of loudness, pitch and timbre. The program may be useful in teaching about the nature of sound sensation.
