Subtractive
What is ‘music theory’ primarily concerned with?
The study of the practices and possibilities of music.
What is the standard digital audio file format that stores waveform data without compression?
WAV
Which algorithm is commonly used in MP3 compression to remove inaudible sounds and reduce file size?
a) Huffman Coding
b) Fast Fourier Transform
c) Perceptual Coding
d) Run-Length Encoding
c) Perceptual Coding
MIDI (Musical Instrument Digital Interface) is a protocol used for digital music production. What does MIDI transmit?
Answer: b) Musical notes and control signals
Which of the following is a machine learning technique used in AI-generated music?
a) Reinforcement Learning
b) Markov Chains
c) Dijkstra’s Algorithm
d) RSA Encryption
Answer: b) Markov Chains
In digital audio processing, what does a Fourier Transform help analyze?
a) The frequency components of a sound wave
b) The length of an audio track
c) The metadata of a music file
d) The volume level of a song
Answer: a) The frequency components of a sound wave
MP3 files maintain the highest possible audio quality because they use lossless compression.
TRUE OR FALSE
Answer: False (MP3 uses lossy compression, which removes some audio data to reduce file size.)
Auto-Tune, a pitch correction software, works by shifting the tempo of a recording.
TRUE OR FALSE
Answer: False (Auto-Tune adjusts pitch, not tempo.)
Digital Signal Processing (DSP) techniques are essential for creating sound effects, reverb, and equalization in music production.
TRUE OR FALSE
Answer: True
AI-generated music models like OpenAI’s Jukebox use deep learning to generate realistic audio compositions.
TRUE OR FALSE
Answer: True
Lossless audio formats such as FLAC and ALAC preserve all original sound data without compression.
TRUE OR FALSE
Answer: True
What is the primary purpose of a Digital Audio Workstation (DAW)?
Answer: b) To edit and produce digital music
Which data structure is commonly used in music recommendation algorithms like those in Spotify or Apple Music?
Answer: b) Graph
In audio synthesis, which technique involves breaking down complex waveforms into sine waves?
Answer: a) Additive Synthesis
The Nyquist Theorem states that the sampling rate of digital audio should be at least twice the highest frequency to avoid aliasing. What is the standard sampling rate used in CD-quality audio?
Answer: b) 44.1 kHz
Music Information Retrieval (MIR) systems often use Mel-Frequency Cepstral Coefficients (MFCCs) to analyze:
Answer: c) The spectral features of audio
Lossy compression formats like MP3 and AAC remove frequencies that are less noticeable to the human ear to reduce file size.
TRUE OR FALSE
Answer: True
In MIDI technology, a file contains recorded sound waves, just like MP3 files.
Answer: False (MIDI files store note and control data, not actual sound.)
Autoencoder neural networks can be used in music generation by learning compressed representations of music and reconstructing similar patterns.
TRUE OR FALSE
Answer: True
In algorithmic composition, genetic algorithms have been used to evolve music by applying selection, mutation, and crossover principles.
TRUE OR FALSE
Answer: True
Reverb is a type of digital effect that primarily modifies the frequency spectrum of a sound without altering its spatial characteristics.
TRUE OR FALSE
Answer: False (Reverb simulates the effect of sound reflections, creating a sense of space and depth.)
