Question 6

what is a mini disc and how is it recorded?

Answer 6

A minidisc is a disc of 64mm diameter inside a plastic shell.
It is recorded using a laser to alter magnetic information on the disc. In order to alter the information, the disc has to be heated to a high temperature, meaning that if left on a desk near a magnet, it should remain unaffected, unless you heat the disc to the required 180°C.

Question 7

When were mini discs used?

Answer 7

1990s and 2000s

Question 8

What is a Compact Disc (CD)?

Answer 8

A compact disc is a portable storage medium that can be used to record, store and play backaudio, video and other data in digital form.

A standard compact disc measures 120 mm, across, is 1.2 mm thick, weighs between 15 and 20 grams; they have a capacity of 80 minutes of audio.

Question 9

How do you record onto a CD?

Answer 9

A CD works by focusing a 780 nanometer wavelength semiconductor laser onto a single track of the disc. As the disc rotates, the laser beam measures differences in the way light is reflected off the polycarbonate layer on the bottom of the disc, converting it to sound.

Question 10

When were CDs mainly used?

Answer 10

1985s - 2010

Question 11

What is an MP3 player?

Answer 11

It’s a compressed digital audio file. A player stores these files on a memory chip so that you can play it back at your leisure. Contains a miniature hard disk drive, which can store huge quantities of data.

MP3s usually contain music, but the format is also used for general audio files such as audiobooks and podcasts.

Question 12

Question 16

What does it mean if an Audio Format is Lossless and compressed

Answer 16

Lossless, compressed audio formats will be the same as an uncompressed audio format, however they will not take up space in silent parts.

Question 17

What is normalising?

Answer 17

In music, normalising refers to the process of adjusting the volume levels of audio recordings to a consistent or standardised level. The goal is to ensure that all the tracks or audio files have a similar loudness, making it easier to listen to a collection of songs without significant variations in volume. Normalising does not change the relative balance between the instruments or elements in a mix; it simply adjusts the overall volume to a standardised level.

Question 18

What is impedance?

Answer 18

Impedance is like the electrical resistance that a device or component has.
It’s measured in ohms.
High or low impedance matters when connecting things like headphones or speakers to audio equipment. Matching impedance helps avoid problems with sound quality and volume. If you connect devices with mismatched impedance, you might get issues like distorted sound.

Question 19

Name 3 rock Artists

Answer 19

1. Queen
2. Nirvana
3. The Artic Monkeys

Question 20

What is the proximity effect?

Answer 20

**The proximity effect is when you get an increase of low frequencies because you move the mic closer to the source. The closer you get the bigger the bass.
**
This can create problems but if you create a low frequency roll off it should fix the issue.
