Question and Answers [100% Correct] 2025
What is the primary purpose of a compressor in audio engineering?
A compressor controls the dynamic range of an audio signal by reducing the level of the loudest
parts and boosting the softer ones.
What is the difference between analog and digital audio signals?
Analog audio signals are continuous waveforms, while digital audio signals are discrete samples of
sound at specific intervals.
Explain the concept of sample rate in digital audio.
Sample rate refers to the number of samples of audio taken per second, typically measured in
Hertz (Hz), with common values like 44.1kHz or 48kHz.
What does the term "bit depth" refer to in digital audio?
Bit depth defines the resolution of each audio sample, determining the dynamic range and the
amount of detail captured in the signal.
What is the role of an equalizer (EQ) in audio processing?
An equalizer adjusts the balance between different frequencies in an audio signal, enhancing or
reducing specific frequency ranges to achieve a desired sound.
What is clipping in audio?
Clipping occurs when an audio signal exceeds the maximum level that a system can handle,
resulting in distortion and a loss of audio quality.
Define the term "signal-to-noise ratio" (SNR) in audio.
Signal-to-noise ratio is the ratio between the desired signal and unwanted background noise, with
a higher ratio indicating clearer audio.
1
,What is the difference between a dynamic microphone and a condenser microphone?
Dynamic microphones use an electromagnetic diaphragm to capture sound, while condenser
microphones use a capacitor and require an external power source.
Explain the concept of phase cancellation in audio.
Phase cancellation occurs when two identical audio signals are inverted in polarity and combined,
causing them to cancel each other out.
What is the purpose of a high-pass filter (HPF)?
A high-pass filter removes low-frequency sounds below a certain cutoff frequency, allowing higher
frequencies to pass through.
What is a low-pass filter (LPF)?
A low-pass filter removes high-frequency content above a set cutoff point, allowing lower
frequencies to pass through.
What is the purpose of a limiter in audio processing?
A limiter is used to prevent the audio signal from exceeding a set threshold, ensuring that the
output does not distort or clip.
What is a DAW, and what is its role in audio engineering?
A DAW (Digital Audio Workstation) is software used for recording, editing, mixing, and producing
audio content.
Explain the function of reverb in audio production.
Reverb is an effect that simulates the natural reflections of sound waves in a physical space,
adding depth and ambiance to the audio.
What is the difference between mono and stereo audio?
2
, Mono audio consists of a single channel of sound, while stereo audio uses two channels to create
a sense of space and directionality.
What is the purpose of a sound card or audio interface in a computer-based recording setup?
A sound card or audio interface converts analog audio signals into digital data for recording and
vice versa for playback, ensuring high-quality audio performance.
What is the function of an audio mixer in a live sound environment?
An audio mixer combines multiple audio sources, adjusts their levels, and applies processing such
as EQ and effects for a balanced sound output.
What is the Nyquist-Shannon sampling theorem?
The Nyquist-Shannon theorem states that a signal must be sampled at least twice the highest
frequency contained within the signal to accurately reconstruct it.
What is the function of a patch bay in a recording studio?
A patch bay provides a convenient and organized way to route audio signals between different
pieces of equipment without having to physically plug and unplug cables.
How does a parametric equalizer differ from a graphic equalizer?
A parametric equalizer allows precise control over frequency, bandwidth, and gain for each filter,
while a graphic equalizer offers fixed frequency bands with visual sliders.
What is the difference between direct and indirect sound in acoustics?
Direct sound comes straight from the source to the listener's ears, while indirect sound is
reflected off surfaces before reaching the listener.
What is the purpose of a noise gate in audio engineering?
A noise gate is used to eliminate unwanted background noise by cutting off the audio signal when
it falls below a certain threshold.
