What does a compressor's attack time control?
Answer: How fast it reduces gain after the signal crosses the threshold
Attack time sets how quickly the compressor clamps down once the signal exceeds the threshold.
A ratio of 4:1 means that for every 4 dB above the threshold, the output increases by how much?
Answer: 1 dB
A 4:1 ratio passes only 1 dB of output for every 4 dB of input over the threshold.
What is the practical effect of a fast release time on a sustained vocal?
Answer: The compressor can 'pump' or breathe as gain recovers quickly
A very fast release lets gain spring back quickly, which can cause audible pumping.
What does the 'knee' setting on a compressor determine?
Answer: How gradually compression engages around the threshold
A soft knee eases compression in gradually, while a hard knee applies it abruptly at the threshold.
Makeup gain on a compressor is used to do what?
Answer: Restore perceived loudness lost to gain reduction
Makeup gain compensates for the level drop caused by compressing the loud peaks.
Which compressor type is generally prized for fast, transparent peak control?
Answer: FET compressor
FET compressors react very quickly, making them good for transient and peak control.
What is dynamic range in an audio signal?
Answer: The difference between the quietest and loudest parts
Dynamic range measures the span between the softest and loudest levels in a signal.
