Audio Engineering I Exam 3 Actual Test with Answers
What is the difference between Digital and Analog recording? - correct answer Digital-
unlimited tracks, analog - limited to tape physical size
Analog - continually varying signal. Digital, fixed number of measurements per second.
What is a DAW? - correct answer Digital Audio Workstation
What is the best DAW to work with? - correct answer The one you can earn the most money
with and know how to use
What does Sample Rate mean? - correct answer How many time per second a voltage is
measured.
What does bit depth mean? - correct answer How accurately the voltage is measured.
What is the sample rate and bit depth for CDs? - correct answer 44.1kHz, 16bit
What is the sample rate and bit depth for DVDs? - correct answer 48kHz, 24bit
What happens when the sample rate is lowered? - correct answer The accuracy of the audio
recording suffers.
What is meant by Dynamic Range? - correct answer The difference between "it's" loudest and
softest portions.
Dynamic Range of a 16bit recording is: - correct answer About 96dB
Dynamic Range of a 24bit recording is: - correct answer About 144dB
Regarding Bit Depth, each bit increases dynamic range by how much? - correct answer 6 dB
What does the Nyquist Theorem state? - correct answer Sample rate is at least 2x greater than
the highest frequency to be recorded.
What is meant by Quantizing? - correct answer Rounding the sample value to the closest bit
depth number.
What is meant by Dithering? - correct answer Adding a small amount of noise into the
conversion process to improve the signal's performance when down sampling.
