Q

A process in which computers capture/record sound waves in electronic format. In simple terms, it means capturing the state or quality of a particular sound wave a set number of times each second. Measured in kilohertz (KHz)

A

Sampling

28
Q

Loudness

A

Amplitude

29
Q

How high or low the tone

A

Frequency

30
Q

Qualities that differentiate the same note played on different instruments

A

Timbre

31
Q

Measurement of the number of characteristics of a particular sound captured during sampling

A

Bit depth

32
Q

A

CD Quality

33
Q

Sound format developed in the 1960s to carry telephone calls over the first digital lines

A

Pulse Code Modulations (PCM)

34
Q

A

WAV

35
Q

Broadcast of data that is played on your computer and immediately discarded

A

Streaming media

36
Q

Interface between a computer and a device for simulating musical instruments. Rather than sending large sound samples, a computer can simply send “instructions” to the instrument describing pitch, tone, and duration of a sound. Because this file is made up of a set of instructions rather than a copy of the sound, modifying each component of the file is easy. It is possible to program many channels/“voices” of music to be played simultaneously, creating symphonic sound

A

Musical Instrument Digital Interface (MIDI)

37
Q

Powerful speaker capable of producing extremely low-frequency sounds

A

Subwoofer

38
Q

Nomenclature for multiple speakers that follows a simple format in which x is the number of satellites with 1 subwoofer

A

X.1 system

39
Q

Part of a connector into which a plug is inserted

A

Jacks

40
Q

A special connector that enables you to connect a sound card directly to a 5.1 speaker system or receiver. Comes in both a coaxial version and optical version

A

Sony/Philips Digital Interface (S/PDIF or SPDIF)

41
Q

Software that compresses or decompresses media streams

A

Codec

42
Q

File containing 2+ separate, compressed tracks, typically an audio track and a moving-picture track

A
