The Audio Precision Fundamentals of Audio Test and Measurement 5-Disc Instructional DVD Set is a structured educational resource delivering in-depth instruction on audio testing principles, measurement techniques, and signal analysis. Presented by engineer Mike Wolfe, this multi-disc set equips audio professionals—engineers, technicians, and students—with practical knowledge spanning analog and digital audio domains, from basic I/O characterization through advanced protocol testing and certification requirements.
Technical Specifications
The course covers digital audio sample rates including 8 kHz (telecom), 16 kHz (wideband voice), 44.1 kHz (CD), 48 kHz (pro audio), 96 kHz (stereophile), and 192 kHz (HDMI). Bit depth instruction addresses 8-bit (256 levels), 16-bit (65,536 levels, 96 dB dynamic range), and 24-bit (16.7 million levels, 144 dB dynamic range) resolutions. Nyquist frequency concepts and dBFS reference definitions are explained in relation to sample rate and bit depth specifications.
