MUSTC220Fall Class Info

Our textbook is Modern Recording Techniques by David Miles Huber

Here is the syllabus for the class in PDF format

PowerPoint Presentations

Week 1: A brief overview of the class and how it fits into the various degree options. The recording chain as a process and a business.

Week 2: An introduction to acoustics. An analysis of sound. Wave propagation theory as it relates to sound. Waveform terminology including pitch vs. frequency and loudness vs. amplitude. The threshold of hearing vs. the threshold of pain andthe biology of the human hearing system..

Week 3: Start where we left off last week, then: the harmonic overtone system including the fundamental, overtones, partials, inharmonic tones and their relationship to timbre. Sound envelopes and interior dynamics including attack, decay, sustain, and release.

Week 4: Measuring the loudness levels using the decibel scale. Metering systems including R.M.S. and peak. Direction perception and the binaural effect, the beating effect, the masking effect, and the Doppler effect.l

Week 5: The Fletcher Munson curves, the Eyring equations, studio acoustics and basic studio construction considerations. Single wall, staggered studs, and double wall techniques. Standing waves and how to avoid them. Near-field vs. far-field monitoring. The 85 decibel monitoring standard.

Week 6: Introduction to electricity and electronics in theory and practice. What electricity is and how it works. Resistance, voltage, current, watts, and impedance as it relates to audio. Alternating vs. direct current, Ohm's Law and it's applications.

Week 7: Introduction to microphones by tracing their history and development. Carbon microphone, ceramic microphone, and crystal microphone designs lead into modern microphone designs like ribbons and moving coils.

Week 8: More recent microphone technology is introduced with condenser and various pressure zone designs. Polarity response patterns, impedance, and specifications will be covered. Specialized microphone designs including parabolic, shotgun, and surveillance applications.

Week 9: Stereo microphone techniques vs. multi-track techniques. Stereo microphone placement configurations including A/B, M/S, and X/Y. Multi-microphone set ups, phase cancellation, and the three to one rule. Close vs. distant placements and the multi-track studio session vs. the live sound reinforcement venue.

Week 11: Review for Final
