Partner Questions • 1. What is your name? • 2. What’s your favorite aspect of audio technology? • 3. What is your favorite music that you are listening to now? • 4. What’s the best present you received over the holidays?
Knowledge Quiz • Test what you know • Don’t worry, it’s not graded • Some questions you may know, some you may not have learned yet • We’ll go over the answers when you are done
Topics for Audio Tech. II • Lines and Interconnections • What affects signal flow? • Balanced vs. Unbalanced lines • High vs. Low Impedance • Resistance (Ohms) and voltages • DI and Splitter Boxes • Patchbays, distribution of sound
Signal Flow • Principles of Stereo Sound, binaural • Mic placement and panning techniques • Signal Formats • Signal flow in live sound and multitrack recording • Analysis of various signal flow scenarios What are some reasons why signal flow is so important?
Mixers • What do mixers allow us to do? • Simple vs. Multitrack • Mixing path and gain stages • Analog vs. digital consoles • Mixing approaches and operation • Inserts and Aux. sends
Types of Signal Processors • What does a signal processor do? • How to read and understand equipment specs. • What kind of effects relate to what type of process? For example: Dynamics, Time, Phase, Timbre, Frequency, etc. Power Amplifiers
Advanced Signal Processing • What is a filter? • Spectral Processing • Advanced Compression and EQ • Concepts of dynamics and decibel levels • How is human hearing measured? • What frequencies can we hear? • When does sound cause hearing damage? • In what situations can this happen? • What is the dynamic range of various sources?
Harmonic Distortion • Analog vs. Digital • Concepts of Clipping • Advanced distortion concepts • Uses for harmonic distortion: • When is distortion good and when is it bad? • (End of material for mid-term exam)
Mechanisms • What are mechanisms? • Outboard Equipment • Types of filters • Reverb types, delay, echo • Software Plug-ins • Analog vs. Digital Devices
Consoles and I/O Modules • What does I/O stand for? • Console Architecture • Channel & Monitor Path • Learning the SSL • Understanding pre/post • Aux Sends • (All has to do with signal flow)
In Short: • Signal Flow! • Signal Processing • Harmonic Distortion • Advanced Dynamics • Mechanisms/Modules • Consoles
QUIZZES • Almost Every week (6 total): • Quick test of main topics from the previous week. • You must be here to take it! • All short answer
ASSIGNMENTS • Take-home projects • Usually involve some research and writing • Due on the day listed on syllabus • Graded on content and effort • Be sure to ask questions before taking them home! (You can e-mail me, too)
EXAMS • Mid-term and final • Counts for 45% of your grade! • I will allow for challenging of quiz and exam answers • Class takes a vote, decides if you get the point • Possible chances for extra credit…
Give it your best effort! • Come to class! • Remember: This is what you love to do and is going to be your profession • Never hesitate to talk to me or send an e-mail. COMMUNICATE! If you don’t tell me, I have no way of knowing. • Have fun… yes there are tests, but it’s more about what you learn.
