Quiz 3

Question 1

Sampling

Answer 1

(1) Examining an analog signal at regular intervals defined by the sampling frequency. (2) A process whereby a section of digital audio repre- senting a sonic event, acoustic or electroacoustic, is stored on disk or into electronic memory.

Question 2

Sample Frequency 44.1 48 96

Answer 2

The frequency (or rate) at which an analog signal is sampled. Also called sampling rate.

Question 3

Bit Depth 16 24

Answer 3

Describes the potential accuracy of a particular piece of hardware or software that processes audio data. In general, the more bits avail- able, the more accurate the resulting output from the data being processed. Also called bit depth and resolution.

Question 4

DAW

Answer 4

digital audio workstation: A multifunc- tional hard-disk production system, controlled from a central location, that is integrated with and capable of being networked to other devices, such as audio, video, and MIDI sources, within or among facilities. Generally, there are two types of DAW systems: computer-based and integrated.

Question 5

Server

Answer 5

A running instance of an application capable of accepting requests from the client and giving responses accordingly.

Question 6

CD

Answer 6

a digital optical disc data storage format

Question 7

CD-R

Answer 7

A digital optical disc storage format. A CD-R disc is a compact disc that can be written once and read arbitrarily many times.

Question 8

DVD

Answer 8

digital versatile disc: A compact disc providing massive data storage of digital-quality audio, video, and text.

Question 9

Blu-ray

Answer 9

High-density optical disc format developed to enable recording, playback, and rewriting of high-definition media.

Question 10

MIDI

Answer 10

Musical Instrument Digital Interface: A protocol that allows synthesizers, drum machines, sequencers, and other signal-processing devices to communicate with or control one another or both.

Question 11

Firewire

Answer 11

A technology that enables isosynchronous service while providing the bandwidth needed for audio, imaging, video, and other streaming data. Isosynchronous service means it guarantees latency—the length of time between a requested action and when the resulting action occurs. FireWire offers a standard, simple connection to all types of electronics, including digital audio devices, digital VCRs, and digital video cameras as well as to traditional computer peripherals such as optical drives and hard-disk drives. FireWire can support up to 63 devices on a single bus.

Question 12

Balanced audio Conductor

Answer 12

A pair of ungrounded conductors whose voltages are opposite in polarity but equal in magnitude.

Question 13

Unbalanced audio Conductor

Answer 13

A line (or circuit) with two conductors of unequal voltage.

Question 14

.aiff

Answer 14

Short for Audio Interchange File Format. An Apple audio format standard. This is a professional lossless and uncompressed format.

Question 15

.wav

Answer 15

Short for Waveform Audio Format. A Microsoft/IBM audio file format standard. This is a professional lossless and uncompressed format.

Question 16

.mp3

Answer 16

Short for MPEG-2 Audio Layer III format. A Moving Picture Experts Group audio file format standard. This is a lossy and compressed format. It removes data from sounds using complicated algorithms and masking principles. It’s a consumer level format commonly used on the internet
