Question 1

A MIDI sequencer records _____________.&#10;A) performance gestures.&#10;B) music.&#10;C) audio.&#10;D) the sequence of songs on an album.

Accepted Answer

A MIDI sequencer records performance gestures, such as note on/off, velocity, and other control changes, rather than actual audio or music.

Question 2

The result of a sequencer recording is called ____________.&#10;A) a step-wise recording.&#10;B) a .mid file.&#10;C) a .wav file.&#10;D) a MIDI arpeggiator.

Accepted Answer

The result of a sequencer recording is typically saved as a MIDI file (.mid), which can be played back on a variety of devices and software programs that support MIDI playback. A .wav file is a digital audio file format, and while a sequencer recording may be converted to a .wav file for further processing or distribution, the initial recording itself would not typically be referred to as a .wav file. Step-wise recording refers to the process of inputting notes or other musical data one at a time, as opposed to playing them in real time or recording multiple tracks simultaneously. A MIDI arpeggiator is a type of software or hardware device that automatically generates arpeggios (chord sequences) based on input from MIDI controllers, but it is not directly related to the result of a sequencer recording.

Question 3

Data compression __________________.&#10;A) adds punch to a mix.&#10;B) reduces file size at the expense of sound quality.&#10;C) improves sound quality at the expense of file size.&#10;D) control the dynamic range of a track.

Accepted Answer

Data compression is the process of reducing the size of a file by removing redundant information. This reduction in size often results in a loss of sound quality, as some of the original data is discarded. Therefore, option B, "reduces file size at the expense of sound quality," is the correct choice.

Question 4

Data compression is used to ________________.&#10;A) make audio files smaller so they upload/download more quickly.&#10;B) send audio on the Internet.&#10;C) control the dynamic range of a track.&#10;D) improve reliability of data.

Accepted Answer

Data compression is the process of reducing the size of a file without losing any important data. This makes it more efficient to upload/download files, making it possible to send audio over the internet with less bandwidth. It does not have any impact on controlling dynamic range or improving reliability.

Question 5

A minimum bitrate of _______________ is necessary for CD quality audio.&#10;A) 128 kbps.&#10;B) 160 kbps.&#10;C) 192 kbps.&#10;D) 224 kbps.

Accepted Answer

The answer of A minimum bitrate of _______________ is necessary...

Question 6

A .wav file is ________________.&#10;A) compressed for PC's.&#10;B) not compressed.&#10;C) always 16-bit.&#10;D) always 44.1 kHz.

Accepted Answer

A .wav file is not compressed, which means it maintains its original audio data and quality. It can be a variety of bit depths and sample rates, so it is not always 16-bit and 44.1 kHz.

Question 7

With an mp3 file, a low bitrate provides ____________.&#10;A) small filesize and high sound quality.&#10;B) small filesize and low sound quality.&#10;C) large filesize and high sound quality.&#10;D) large filesize and low sound quality.

Accepted Answer

A low bitrate means that there is less data used to compress the audio file, resulting in a smaller filesize. However, this also means that the audio quality is reduced because there is less information available to accurately represent the sound. Therefore, a low bitrate provides a small filesize and low sound quality.

Question 8

A codec with lossless compression is ______________.&#10;A) MPEG 4&#10;B) AAC&#10;C) Ogg Vorbis&#10;D) FLAC

Accepted Answer

FLAC stands for Free Lossless Audio Codec, which is a codec specifically designed for lossless compression of digital audio. This means that the compressed file maintains the full quality of the original audio without any loss. The other options listed (MPEG 4, AAC, and Ogg Vorbis) all use lossy compression, which means that some audio data is discarded during compression, resulting in a smaller file size but a lower quality audio output.

Question 9

A ripper converts __________ to _____________.&#10;A) mp3 files to .cda files&#10;B) CD tracks to mp3 files&#10;C) analog audio to digital&#10;D) aac files to mp3 files

Accepted Answer

A ripper is a software program that converts CD tracks to digital audio files, usually in the mp3 format, making it the best choice. A is incorrect because .cda files are already digital audio files and cannot be converted from mp3 files. C is incorrect because while a ripper does convert analog audio to digital, it specifically refers to CD tracks. D is incorrect because aac files are already digital audio files and do not need to be converted to mp3 format.

Question 10

An mp3 encoder converts ___________ to ____________.&#10;A) mp3 files to .wav files.&#10;B) wav files to mp3 files.&#10;C) low bitrate mp3 files to high bitrate mp3 files&#10;D) RazorLame files to standard audio files.

Accepted Answer

An mp3 encoder converts uncompressed WAV files to compressed mp3 files. So, option B - wav files to mp3 files - is the correct choice.

Question 11

CDBaby is _____________.&#10;A) a website to download iTunes.&#10;B) a service that can convert a CD into data-compressed files.&#10;C) a service that prepares your music for encoding.&#10;D) a CD replication service.

Accepted Answer

The answer of CDBaby is _____________.&#10;A) a website to download...
