Cook Records was a record label founded by Emory Cook (1913–2002), an audio engineer and inventor. From 1952 to 1966, Cook used his Sounds of our Times and Cook Laboratories record labels to demonstrate his philosophy about sound, recording equipment, and manufacturing techniques.
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. These tones are recorded then read during the duplication process to detect if there ...
Many audio components are tested for performance using objective and quantifiable measurements, e.g., THD, dynamic range and frequency response. Some take the view that objective measurements are useful and often relate well to subjective performance, i.e., the sound quality as experienced by the listener. [12]
The Isobarik, like the Sara and Kan that were developed in the 1970s and 80s, was designed to work best near room boundaries. [8] Manufacturer's leaflets advise positioning of the speaker close to a rear wall and approximately 2 to 3 feet (60 to 90 cm) from corners. [4] [7] The trade-off is the less than solid stereo image.

For a multiple sound source speaker system, the measurement should be carried out for all sound sources (woofer, bass-reflex vent, midrange speaker, tweeter...). These measurements are easy to carry out, can be done at almost any room, more punctual than in-box measurements, and predicts half-space measurements, but without directivity information.
Audiophiles in the 1970s and 1980s preferred to buy each component separately. That way, they could choose models of each component with the specifications that they desired. 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.
When a winter storm is on the way, everyone rushes to the grocery store. If you don't join them quickly, the shelves could be bare by the time those first flurries fall. You'll probably buy extra ...
The perception of analog audio being demonstrably superior was also called into question by music analysts following revelations that audiophile label Mobile Fidelity Sound Lab had been covertly using Direct Stream Digital files to produce vinyl releases marketed as coming from analog master tapes, with lawyer and audiophile Randy Braun stating ...
