Dante Level 1 - Chapter 4 - Basics of Digital Audio

What is the term used to describe the moment when air molecules are pushed forward by vibration in the context of sound waves?

• Refraction

• Amplitude

• Compression

• Rarefaction

What term is used to describe the digital representation of a sound wave at steady intervals?

• Binary bits

• Audio clip

• Sample

• Waveform

According to the Nyquist theorem, how many times should the sample rate be compared to the highest frequency you wish to capture?

• Twice the frequency

• The same as the frequency

• Half the frequency

• Four times the frequency

What is the result of sampling below the Nyquist rate, according to the explanation in the text?

• The original wave is perfectly captured.

• The sample rate is optimized.

• An alias of the original frequency is created.

• The sound quality is enhanced.

What is the purpose of filtering out frequencies above 20 thousand hertz in digital audio?

• To prevent problems with aliases

• To increase the audio quality

• To reduce the file size

• To match the human hearing range

Which sample rates does the Dante device in the video support?

• 44.1 kHz

• 192 kHz

• 48 kHz

• 96 kHz

What happens if you try to make a patch between two devices that are running at different sample rates, according to the text?

• The system automatically adjusts the sample rates.

• The controller won't let you do it.

• The devices will connect but with reduced audio quality.

• The sample rates will be averaged out.

What is the role of the clock leader in a Dante system?

• It selects the devices that can connect to each other.

• It distributes a time, date, and data stamp so accurate that any device can then derive whatever sample rate or frame rate that they wish from that reference.

• It controls the volume levels of all devices in the network.

• It converts different sample rates to a single unified rate.

What is the consequence of having two devices at different sample rates that cannot digitally connect?

• The devices will not work together at all.

• The devices will connect but will not synchronize.

• The devices will synchronize but will not pass audio.

• The devices will pass audio but at a lower quality.

What is the purpose of using a sample rate converter in a digital audio network?

• To increase the speed of the network

• To allow devices operating at different sample rates to communicate

• To reduce the size of the audio files

• To improve the quality of the audio signal
