Reprint of the 1980 handbook produced by National Semiconductor for the application of operational amplifiers to audio circuits. The introduction provides a detailed explanation of the IC parameters applied to audio followed by chapters on design of preamps, tone controls, filters, power amplification, radio, and others. The "Floobydust" section is a mixed bag of miscellaneous topics not covered elsewhere.

"The topics that are covered are done well, with both practical overviews and all the mathematical detail you need to design high-quality circuits." --Charles Hansen
