On some cassettes was the use of digital tapes to prepare the wide-track duplication masters. Recording a short test toneburst at the beginning and end of the program material on the cassettes, to detect for any loss of audio frequencies in the audio spectrum.

Beginning approximately in the 1950s, a number of magazines devoted to hi-fi enthusiasts and aficionados seeking to assemble an ideal home audio system arose, such as High Fidelity, Audio, Gramophone, The Absolute Sound, Stereophile, and The Boston Audio Society Speaker.

This means the microphone must be positioned precisely equidistant from the two speakers if 'comb-filter' effects (alternate peaks and dips in the measured room response at that point) are to be avoided. Positioning is best done by moving the mic from side to side for maximum response on a 1 kHz tone, then a 3 kHz tone, then a 10 kHz tone.

In the 1980s, several audiophile magazines became available, offering reviews of components and articles on how to choose and test speakers, amplifiers, and other components.
