The department has developed many software tools for teaching and research.
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. More information.
ESynth is a free program designed to explain the harmonic analysis and synthesis of signals. With ESynth you can create signals by adding together individual sinusoidal waveforms (sinewaves) and study the resulting waveform and spectrum. You can also perform an analysis of an input waveform, to see how a given sound can be represented in terms of a sum of sinewaves. More information.
