This book deals with small-signal audio design: the amplification and control of audio in the analog domain, where the clever stuff is done with op-amps or discrete transistors, usually working at a nominal level of a volt or less. ‘Small-signal design’ is the opposite term to the large-signal technology used in power amplifiers, welding gear, and the electricity distribution grid. Audio signals frequently need to be manipulated, by altering their level, frequency response, routing and so on. It is obviously much more economical to perform these functions on a small signal, rather than a large signal that has already been amplified up to loudspeaker level, and so has tens of volts and several amps to its name.
