Term
| This wave property indicates how many wave cycles are completed per second. |
|
Definition
|
|
Term
| This is considered the normal frequency range of human hearing. |

|
Term
| Using an analog-to-digital converter to sample a sound wave offers the manipulation of these two parameters. |

Definition
| Sampling rate and quantization |
|
|
Term
| This is the term for how many samples are taken per second. |
|
Definition
|
|
Term
Circle the correct answer.
The higher / lower the sample rate, the more completely the analog wave’s shape can be represented digitally. |
|
Definition
|
|
Term
This rule states that in order to faithfully describe the basic characteristics of an analog wave,
the wave must be sampled at a rate that is at least twice that of the highest frequency being recorded. |

Term
Determine if the statement is true or false. If false, correct the statement.
The CD sampling rate is higher than that actually required to digitally reproduce the high pitched tones audible to humans. |
|
Definition
|
|
Term
| The Nyquist Theorem states that as the highest frequency being captured increases, the sample rate used should also increase proportionally. Select the mathematical relationship demonstrated by the Nyquist Theorem. |
|
Definition
|
|
Term
| This lower-quality sample rate captures most of the sound frequencies audible to humans, generates less digital data, and requires less memory than sample rates that capture the full range of frequencies audible to humans. |
|
Definition
|
|
Term
If the highest frequency contained in a particular analog recording is 18,065 Hz, what minimum sampling rate would be required to reproduce the quality of the original sound in digital form?

Definition
|
|
Term
Determine if the statement is true or false. If false, correct the statement.
Higher sample rates are responsible for generating more data, thus requiring more
computer storage space. |
|
Definition
|
|
Term
| These frequencies are recorded using sample rates that capture frequencies two to five times the highest frequency audible to humans. |

Term
Circle the correct response.
Quantization is the process of assigning a wavelength / wave amplitude value to each
sample. |

Definition
|
|
Term
Determine if the statement is true or false. If false, correct the statement.
The more bits used to sample a wave, the more detailed its digital amplitude ranges can be. |
|
Definition
|
|
Term
| This algebraic formula illustrates the bit rate, or number of amplitude values available for quantization. The number of bits used is represented by n. |
|
Definition
|
|
Term
| The formula for bit rate is this type of function. |
|
Definition
|
|
Term
Circle the correct answer.
Sampling error can be reduced by increasing / decreasing both the sampling rate and the quantization. |
|
Definition
|
|
Term
| This term refers to the similarity between the original wave and the digital signal generated by the DAC. |
|
Definition
|
|
Term
| This is the span between the quietest and loudest sound in a recording. |
|
Definition
|
|
Term
| This is the volume or loudness of a sound wave. |
|
Definition
|
|
Term
Circle the correct answer.
Recording at a higher / lower resolution will capture a fuller dynamic range. |
|
Definition
|
|
Term
Determine if the statement is true or false. If false, correct the statement.
If either the sample rate increases, the quantization increases, or both increase, the amount of memory necessary to store a sound file decreases. |
