In the search for improved reproduction of a classical music performance, the technique of time delay compensation is shown to be a useful tool for balance in recording. This paper investigates the importance and validity of small time adjustments in recordings to compensate for variation in distance between spot microphones and a main stereo pair. Conventional recording techniques, psychoacoustic considerations and technological aspects of the use of delays are researched in order to determine their validity in timbral improvement. / Multiple microphone set-ups are used to record both large orchestral works and smaller-scale classical compositions where auxiliary microphones may be needed to ensure an optimum balance in the final mix. Small time delays are derived from calculations involving the distances between microphones, the speed of sound, and humidity and temperature readings from the hall. Proper synchronization of these delays is desirable to preserve phase coherence and combat comb-filter effects. Precise delay units are used to compile musical exerpts for listening tests. / The results reveal any change in sound quality and provide a basis for investigating both the positive and negative effects through objective study of the value of time delay compensation in the live recording reproduction of classical music performances.
