Often, books about signal analysis and processing are either highly theoretical with high-level mathematics or contain oversimplified explanations which cannot answer the questions of how and why adequately. In this book, the writer attempts to explain the theory from a practical viewpoint, using a common-sense way of thinking. The theoretical principles described are mainly applied to speech sounds but the complex nature of these sounds makes this approach suitable to audio signals in general.

The book contains mathematical formulas, but sparsely used, serving as conclusions of the preceding explanations in ‘normal’ language. The more extended mathematical manipulations can be found in the appendice...
