AES Los Angeles 2014
Live Sound Track Event H4
Saturday, October 11, 12:15 pm — 1:15 pm (Room 402 AB)
Historical: H4 - History of Audio Measurement Technology
Presenter:John Murray, Optimum System Solutions - Woodland Park, CO, USA
Abstract:
Starting with early CRT real-time analyzers and strip-chart recorders, moving through LED RTAs to time-gated direct sound and windowing methodologies, to the full dual FFT era, including both dedicated boxes as well as software cards and programs, this presentation will track the historical development of audio measurement systems for sound reinforcement. Systems to be mentioned in the timeline will include HP, Altec, Amber, Arta, Audio Control, Audio Precision (Tektronix), Barclay Badap, B&K, Crown BDP-2 & TEF, General Radio, Goldline, Ivie, Meyer SIM, Neptune (NEI), SIA SMAART, Spectra Foo, UREI Sonipulse, UREI 200/2000 w/HP 7010B, and White Instruments.
Perspective on the practical application and technical progression of these types of measurement systems will be shared. Insight will be presented as to how the advancement of the technology fostered the expansion of knowledge for both the practitioners of system design and tuning, and for the developers of new loudspeaker/processing products. The presenter, John Murray, has made a life-long study of sound-system equalization and the tools used for it. Having experience in all sides of the sound reinforcement industry, his career has been greatly influenced by these measurement systems.
