Abstract: We are developing special-purpose, low-power analog-to-digital converters for speech and music applications, that feature analog circuit models of biological audition to process the audio signal before conversion. This paper describes our most recent converter design, and a working system that uses several copies of the chip to compute multiple representations of sound from an analog input. This multi-representation system demonstrates the plausibility of inexpensively implementing an auditory scene analysis approach to sound processing.

- 01 Jan 1996
TL;DR: A blackboard-based implementation of the 'prediction-driven' approach is described which analyzes dense, ambient sound examples into a vocabulary of noise clouds, transient clicks, and a correlogram-based representation of wide-band periodic energy called the weft.
A Library of Analog Operators Based on the Hodgkin-Huxley Formalism for the Design of Tunable, Real-Time, Silicon Neurons
TL;DR: A library of analog operators used for the analog real-time computation of the Hodgkin-Huxley formalism make it possible to design a silicon (Si) neuron that is dynamically tunable, and that reproduces different kinds of neurons.

Approximation and Optimization of an Auditory Model for Realization in VLSI Hardware
Samuel L. SanGregory
- 01 Aug 1999
TL;DR: An all-digital approximation of the AIM which is suitable for implementation in very large scale integrated circuits is presented and simulation results indicate that the architecture, when implemented in 0.8jtm CMOS VLSI, will sustain real- time operation on a 32 channel system.
