What is the primary purpose of loudness normalization?
-
To ensure consistent loudness levels across different audio sources.
-
To reduce the dynamic range of an audio signal.
-
To improve the clarity and intelligibility of speech.
-
To create a more immersive listening experience.
Loudness normalization aims to ensure that different audio sources, such as songs, commercials, and movies, have similar perceived loudness levels when played back on the same device.
What is the most common method used for loudness normalization?
-
Peak limiting
-
RMS normalization
-
True peak limiting
-
Compression
RMS normalization is a method of loudness normalization that measures the average power of an audio signal over a specified time interval and adjusts the gain accordingly to achieve a target loudness level.
What is the difference between peak limiting and true peak limiting?
-
Peak limiting only affects the highest peaks in an audio signal, while true peak limiting affects the entire signal.
-
Peak limiting is more effective at reducing loudness than true peak limiting.
-
True peak limiting is more computationally expensive than peak limiting.
-
Peak limiting is only used in analog audio processing, while true peak limiting is used in digital audio processing.
Peak limiting only affects the highest peaks in an audio signal, reducing their amplitude to a specified threshold, while true peak limiting analyzes the entire signal and adjusts the gain to prevent inter-sample peaks from exceeding a specified threshold.
What is the purpose of dynamic range control?
-
To reduce the difference between the loudest and softest parts of an audio signal.
-
To increase the overall loudness of an audio signal.
-
To improve the clarity and intelligibility of speech.
-
To create a more immersive listening experience.
Dynamic range control aims to reduce the difference between the loudest and softest parts of an audio signal, making it more consistent and easier to listen to in different environments.
What are the two main types of dynamic range control?
-
Compression and limiting
-
Expansion and gating
-
Ducking and sidechaining
-
Reverb and delay
Compression and limiting are the two main types of dynamic range control. Compression reduces the dynamic range of an audio signal by attenuating the loudest parts, while limiting prevents the signal from exceeding a specified threshold.
What is the difference between compression and limiting?
-
Compression reduces the dynamic range of an audio signal, while limiting prevents the signal from exceeding a specified threshold.
-
Compression is used to reduce the overall loudness of an audio signal, while limiting is used to increase the overall loudness.
-
Compression is typically used on individual tracks, while limiting is typically used on the master bus.
-
Compression is more computationally expensive than limiting.
Compression reduces the dynamic range of an audio signal by attenuating the loudest parts, while limiting prevents the signal from exceeding a specified threshold. Compression is typically used to make an audio signal more consistent and easier to listen to, while limiting is used to prevent distortion and ensure that the signal does not exceed the maximum level.
What is the purpose of a compressor's attack time?
-
To determine how quickly the compressor responds to changes in the audio signal.
-
To determine the amount of gain reduction applied to the audio signal.
-
To determine the ratio of the loudest to softest parts of the audio signal.
-
To determine the threshold at which the compressor starts to apply gain reduction.
The attack time of a compressor determines how quickly the compressor responds to changes in the audio signal. A shorter attack time will cause the compressor to respond more quickly to transients, while a longer attack time will cause the compressor to respond more slowly.
What is the purpose of a compressor's release time?
-
To determine how quickly the compressor responds to changes in the audio signal.
-
To determine the amount of gain reduction applied to the audio signal.
-
To determine the ratio of the loudest to softest parts of the audio signal.
-
To determine the threshold at which the compressor starts to apply gain reduction.
The release time of a compressor determines how quickly the compressor stops applying gain reduction after the signal level drops below the threshold. A shorter release time will cause the compressor to stop applying gain reduction more quickly, while a longer release time will cause the compressor to stop applying gain reduction more slowly.
What is the purpose of a compressor's ratio?
-
To determine how quickly the compressor responds to changes in the audio signal.
-
To determine the amount of gain reduction applied to the audio signal.
-
To determine the ratio of the loudest to softest parts of the audio signal.
-
To determine the threshold at which the compressor starts to apply gain reduction.
The ratio of a compressor determines the amount of gain reduction applied to the audio signal. A ratio of 2:1 means that for every 2 dB increase in the input signal level, the output signal level will increase by 1 dB. A ratio of 4:1 means that for every 4 dB increase in the input signal level, the output signal level will increase by 1 dB, and so on.
What is the purpose of a compressor's threshold?
-
To determine how quickly the compressor responds to changes in the audio signal.
-
To determine the amount of gain reduction applied to the audio signal.
-
To determine the ratio of the loudest to softest parts of the audio signal.
-
To determine the threshold at which the compressor starts to apply gain reduction.
The threshold of a compressor determines the level at which the compressor starts to apply gain reduction. Signals below the threshold will not be affected by the compressor, while signals above the threshold will be attenuated by the amount specified by the ratio.
What is the purpose of a limiter's threshold?
-
To determine how quickly the limiter responds to changes in the audio signal.
-
To determine the amount of gain reduction applied to the audio signal.
-
To determine the ratio of the loudest to softest parts of the audio signal.
-
To determine the threshold at which the limiter starts to apply gain reduction.
The threshold of a limiter determines the level at which the limiter starts to apply gain reduction. Signals below the threshold will not be affected by the limiter, while signals above the threshold will be attenuated to the level of the threshold.
What is the purpose of a limiter's attack time?

The release time of a limiter determines how quickly the limiter stops applying gain reduction after the signal level drops below the threshold. A shorter release time will cause the limiter to stop applying gain reduction more quickly, while a longer release time will cause the limiter to stop applying gain reduction more slowly.
What is the difference between a compressor and an expander?
-
A compressor reduces the dynamic range of an audio signal, while an expander increases the dynamic range.
-
A compressor is used to make an audio signal more consistent and easier to listen to, while an expander is used to create a more dramatic and dynamic sound.
-
A compressor is typically used on individual tracks, while an expander is typically used on the master bus.
-
A compressor is more computationally expensive than an expander.
A compressor reduces the dynamic range of an audio signal by attenuating the loudest parts, while an expander increases the dynamic range by amplifying the softest parts. Compressors are typically used to make an audio signal more consistent and easier to listen to, while expanders are used to create a more dramatic and dynamic sound.
What is the purpose of a gate?
-
To reduce the amount of noise in an audio signal.
-
To prevent feedback in a live sound system.
-
To create a more dramatic and dynamic sound.
-
To isolate a specific sound from the rest of the mix.
A gate is an audio effect that reduces the amount of noise in an audio signal by muting the signal when it falls below a specified threshold. Gates are often used to reduce the amount of background noise in a recording or to prevent feedback in a live sound system.
