The discussion is about what is involved with system design and implementation for the national tour of musical theatre production Pippin, including building the system from the ground up, signal flow, microphone choice and placement, power distribution and grounding issues. There is a matinee and evening performance of Pippin that day if you would like to see and hear the sound system during the performance. (more…)
The goal of PTF is nothing less than a full set of objective measurements of an audio system that correlate with perceived performance. Rather than attempting to map conventional measurements to perception, PTF uses all-new stimulus, reception and analysis techniques. PTF is organized into test modules that are selected from a Virtual Instrument (VI) computer interface. Each module tests an aspect of audio performance that corresponds to human assessment: Tonal Balance, Imaging, Maximum Loudness and Distortion. Each stimulus signal is generated by the VI and converted to an electrical signal by the hardware. The signal is sent to the system under test and received by the PTF microphone array. (more…)
