Best Selling Books by Hugh Scott

Abstract: "This report is concerned with the choice of filters for the estimation and detection from a time-frequency representation of audio signals of partials -- the approximately sinusoidal components, typically generated in harmonic series, of which many musical signals are composed. The report contains a detailed theoretical and experimental comparison between filters with Gaussian and bilateral exponential time envelopes, in terms of performance on noisy data and simplicity of implementation. It is concluded that the exponential filter is better on both counts. There follows a brief examination of the problem of onset detection, in which both additive and multiplicative approaches are examined. Some tentative conclusions are drawn about the most effective way to solve the problem of partial detection in noisy signals."
