A technique for segmenting sounds using processing based on mam(cid:173) malian early auditory processing is presented. The technique is based on features in sound which neuron spike recording suggests are detected in the cochlear nucleus. The sound signal is band(cid:173) passed and each signal processed to enhance onsets and offsets. The onset and offset signals are compressed, then clustered both in time and across frequency channels using a network of integrate(cid:173) and-fire neurons. Onsets and offsets are signalled by spikes, and the timing of these spikes used to segment the sound.
