What is commonly used to convert from unbalanced to balanced?

Direct box

Connecting an electric guitar directly into an audio interface is called:

Direct recording

The two most popular microphones are:

Dynamic and condenser

TorF: Sound in air is a transerve wave.

False

TorF: The maximum amplitude inside the computer is 0 dBSPL.

False

TorF: Vowel sounds are primarily variations of amplitude.

False (Vowel sounds are primarily variations of SPECTRUM, not amplitude)

TorF: The more pulses in a sound wave, the higher the frequency and the lower the pitch.

False (the more pulses in a sound wave, the higher the frequency and the higher the pitch)

Which effect category manipulates timbre and spectrum?

Filter effects

The +4/-10 button next to some line inputs is a:

Gain Stage

A condenser microphone will typically:

Have a better high end frequency response than a dynamic microphone

Frequency is:

How often a wave repeats within a fixed amount of time

Which is a directional polar pattern?

Hyper-Cardioid & Cardioid, Super-Cardioid, & Unidirectional

The polar pattern of a microphone:

Is a diagram that shows from what directions the microphone is sensitive

The frequency response of a microphone is:

Is how sensitive the microphone is across the human hearing range

A directional microphone:

Is useful for isolating a sound source from its environment

Once an audio signal has passed through an Analog to Digital Converter:

It is represented as a stream of binary words

Which is the most important skill when placing a microphone?

Longitudinal, Transverse

The human perception of amplitude is:

Loudness

Which displays shows time on the horizontal (X) and amplitude on the vertical (Y)?

Oscilloscope (The display on the oscilloscope shows time on the horizontal [X] and amplitude on the vertical [Y])

Speakers are:

Output transducers

It is best to monitor:

Outside of the computer

To function, a condenser microphone requires:

Phantom power

When air is less dense than atmospheric pressure due to sound traveling through it, the air is:

Rarefied

A balanced cable:

Rejects noise

Binary means:

Represented by ones and zeros

An Analog to Digital Converter:

Samples an audio signal

Analog to digital conversion is also known as:

Sampling

Signal flow

Which display shows how timbre evolves over time?

Spectrogram/Sonogram

Vowel sounds are primarily variations of:

Spectrum

A 1/4 inch TRS cable can be used in what two ways:

Stereo unbalanced or Mono balanced

Which of the three displays shows X-Time Y-Frequency Z-Amplitude?

The Spectrogram/Sonogram

Dynamic range in a piece of musical equipment is:

The amplitude range in decibels between the noise floor and distortion

Timbre is:

The relative levels of the partials in a sound

Line level is:

The standard operating level used throughout the studio

Monitoring, when recording, means:

To listen to the instrument that is being recorded in real time

Sound traveling through a guitar string is what type of wave?

Transverse

A balanced cable requires:

Two conductors and a shield

A 1/4 inch TS cable is:

Unbalanced

To reduce electrical noise:

Use balanced cables whenever possible

An audio signal is:

Voltage variations

In a typical home studio, where is the A to D converter located?

Within the audio interface

The spectrum analyzer shows:

X-Frequency, Y-Amplitude

The oscilloscope displays shows:

X-Time, Y-Amplitude

The Spectrogram/Sonogram shows:

X-Time, Y-Frequency, Z-Amplitude

A microphone typically converts what type of cable?

XLR

The threshold of hearing is:

0 dB Sound Pressure Level

An electric guitar pickup uses what type of cable?

1/4 inch TS

An electric guitar typically connects via what type of cable?

1/4 inch TS

The range of human frequency perception is roughly

20 Hertz to 20,000 Hertz

Which line level should you use when possible?

+4

The two line level standards are:

+4 (Pro) & -10 (Consumer)

What are two ways to record direct while monitoring through an amp?

-Connect the guitar to the amp and use the amps line out to send signal to the computer -Connect the guitar to a direct box, use the XLR out to go to the computer, and use the parallel 1/4 out to go to the amplifier.

Which of the following are part of the timbre for any given instrument? Check all that apply.

-Frequencies (Timbre is comprised of multiple frequencies) -Partials (Partials are part of the timbre for a given instrument) -Sine Waves (Sine waves represent a single frequency. Since timbre is comprised of multiple frequencies, this means that timbre is also comprised of a multitude of sine waves.)
