COMD 5070 Final Exam Study Guide With Complete Solution What is Science? - Correct Answer-1. Empirical: Based on data 2. Deterministic: Obeys physical laws of cause and effect (not random) 3. Predictive: if you do this...then that will happen; it can influence another one 4. Parsimonious: use simplest explanation possible rather than make unnecessarily complicated - boil it down to its essence, without dumbing down. Semitones (how many semitones in one octave, two octaves, etc.) - Correct Answer-Octave: changes mathematical relationship bw frequencies; doubling (up)/halving (down) of frequency 400= 800 (up) & 200 (down) -12 semitone= 1 octave 200-400Hz=1 octave = 12 semitones 200-800Hz=2 octaves = 24 semitones Sampling Rate (How does it relate to playback quality, file size, frequencies saved in Recording, nyquist, etc.?) - Correct Answer--Sampling Rate (snapshots): (specified in Hz) frequency of numbers stored/written to act as sampled analog signal: discrete snapshots in rapid succession. Linked with quality level. Numbers represent amplitude values; more samples, better can represent original signal. Rapidly changing signal needs more samples/dos to reflect all changes in original. Too low sampling rate & changes missed. Think movie shot @ 30fps looks continuous. Any lower tho would look jerky. -Higher Sampling Rate selection: gives
