Digital Audio Processing

Digital techniques for processing sound described in accessible language! C++ programmers involved in digital signal processing (DSP) for telephony, audio, video, and user interface development will learn how to achieve:

• Normal effects to replicate natural sound processes
• Special effects processing designed to sound unnatural
• Noise reduction
• Signal generation

Learn how to get predictable results when faced with a task and be able to visualize how a system works in general. The author employs a unique blend of theory and practice in explaining the fundamental principles of DSP and the basic mechanisms of human sound perception. In relating DSP principles, the author eschews the standard explanations and mind-numbing math notations in favor of a more intuitive set of explanations of phenomena and theory.

Use the author's practical DSP programming techniques to, compensate for acoustic and instrument limitations. The author walks you through the creation of a practical DSP product - a waveform editor for the desktop - for which full source code is provided.

You get an unprecedented amount of practical, reusable DSP source code. No commercial libraries are used - you get complete source code for:

• A treasure chest of C++ software tools
• C++ source code for a complete commercial-grade wave editor
• C++ software tools for Windows 32-bit sound programming
• DSP and user interface advancements for the WinTel platform
• Optimized assembly functions for DSP

Doug Coulter recalls that his first engineering projects used tubes. He has kept up with technological advances ever since, as he worked in private and public sectors. Doug has worked as a free-lance consultant and writer for the Last 20 years. Consulting projects have included process control, prosthetics for the deaf, hearing aids, embedded system and opsys development, CPU design, audio test equipment, telecom equipment development, and DSP development and instruction. Doug Lives on a farm in the beautiful Blue Ridge mountains, where he grows much of his own food, generates his own electricity, plays drums, guitar, and keyboards, and runs a digital recording studio.
