  1. EQ

  2. Compression

  3. Panning

  4. Reverb
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Reverb is the process of adding a sense of space and depth to an audio recording by simulating the natural reverberation of a room or other space.

Multiple choice

What is the term used to describe the process of converting an analog audio signal to a digital signal?

  1. Sampling

  2. Quantization

  3. Dithering

  4. Normalization
Reveal answer Fill a bubble to check yourself
Correct answer
Explanation

Analog-to-digital conversion (ADC) is the process of converting an analog audio signal to a digital signal by measuring its amplitude at regular intervals and representing it as a series of binary numbers.

Multiple choice

What is the term used to describe the process of converting a digital audio signal to an analog signal?

  1. Sampling

  2. Quantization

  3. Dithering

  4. Normalization
Reveal answer Fill a bubble to check yourself
Correct answer
Explanation

Digital-to-analog conversion (DAC) is the process of converting a digital audio signal to an analog signal by reconstructing the original waveform from the series of binary numbers.

Multiple choice

What is the term used to describe the process of reducing the bit depth of an audio signal?

  1. Sampling

  2. Quantization

  3. Dithering

  4. Normalization
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Quantization is the process of reducing the bit depth of an audio signal by rounding the amplitude values to the nearest discrete level.

Multiple choice

What is the term used to describe the process of adding noise to an audio signal before quantization?

  1. Sampling

  2. Quantization

  3. Dithering

  4. Normalization
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Dithering is the process of adding noise to an audio signal before quantization to reduce the effects of quantization error.

Multiple choice

What is the term used to describe the process of adjusting the overall level of an audio signal?

  1. EQ

  2. Compression

  3. Panning

  4. Normalization
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Normalization is the process of adjusting the overall level of an audio signal to a specified target level, typically 0 dBFS.
