Abstract
At the University of Nebraska, previous research has been done in the quantification of time varying directivity of played musical instruments using 13 channel anechoic recordings of solo passages. The proposed quantifiers involve measures of the extent to which directivity changes in magnitude as well as how often the directivity changes in spatial direction, using various time windows of analysis from 0.2 to 1 s. In this paper, these proposed quantifiers are applied to 5 channel anechoic recordings of a full orchestra for a Brahms symphony and a Mozart symphony. With silent sections removed from the recordings, the time varying directivity properties of musical instruments are more accurately examined within the context of played notes from two stylistically different symphonies.
