Music Studies 4711 - Final Exam Study Guide You will be asked to match each of the equations with its description. Know what each of the following equations represents (and in order to answer later multiple choice questions, how to use it): f c ± kf m to determine side band frequencies in FM sound synthesis f = 1/p given either the period or a frequency value, you can determine the other P = 1/SR The sample period (P) is the inverse of the sample rate dB = 20 log ( Amp(new) / Amp(orig) ) to determine relative amplitude values in decibels N = .5 * SR to determine the Nyquist frequency : What is the Nyquist frequency? The highest frequency that can be represented using a given sample rate. F' = | NS - F | to determine the alias of a frequency given a sample rate M = LRSC to determine how much memory a certain length sound will consume given the Length (L) the Sample Rate (R) the Sample Size on Bytes (S) and the number of Channels (C) Amp(Pn) = Amp(P1) / n to determine the amplitude of a partial (Pn) of square wave or sawtooth wave Freq(Pn) = n * Freq(P1) to determine the frequency of the nth harmonic partial (Pn) of any fundamental frequency(P1) Know what each of the following equations represents: Yn = .5x n + .5x n-1 a non-recursive low pass moving average filter Yn = .5x n + .5y n-1 a recursive low pass moving average filter Yn = .5x n - .5x n-1 a non-recursive high pass moving average filter The remainder of the exam is multiple choice Know the frequency range of the human auditory system (20Hz - 20kHz) the most sensitive range of the human auditory system (3000Hz-5000Hz) the amplitude range of the human auditory system (120dB) the ratios of octave (1:2) perfect fifth (2:3) perfect fourth (3:4) equal tempered semi-tone (about 1.059) 10 times as loud (20dB)
