Commonly used sound quality terms explained

Timbre: also known as timbre quality, one of the basic attributes of sound. For example, erhu and pipa have different timbres.

Coloration: The opposite of natural neutrality in music, where the sound is stained with characteristics that the program itself does not have, such as the sound obtained by speaking into a can. Coloration indicates that some components are added (or reduced) in the reproduced signal, which is obviously a distortion.

Distortion: The output of a device cannot completely reproduce its input, resulting in waveform distortion or increase or decrease in signal components.

Dynamic: Allows recording of the ratio of maximum information to minimum information.

Transient response: The ability of an instrument to follow sudden signals in music. An instrument with good transient response should respond immediately when a signal comes, and stop abruptly when the signal stops, without any delay. (Typical instrument: piano)

Signal-to-noise ratio: Also known as the signal-to-noise ratio, it is the comparison between the useful components of the signal and the noise, often expressed in decibels. The higher the signal-to-noise ratio of a device, the less noise it produces.

Air: An acoustic term used to describe the openness of the treble, or the space between instruments in the sound field. In this case, the high frequency response can extend to 15kHz-20kHz. Antonyms include "dull" and "thick".

Low-frequency extension: refers to the lowest frequency that an audio device can reproduce. It is a measure of how far a sound system or speaker can go when reproducing bass. For example, a small subwoofer can extend its low frequency to 40Hz, while a large subwoofer can extend it to 16Hz.

Bright: refers to highlighting the high frequency band of 4kHz-8kHz, at which the harmonics are relatively stronger than the fundamental wave. There is nothing wrong with brightness itself, and live concerts all have bright sounds. The problem is to grasp the right degree of brightness. Too bright (even howling) will be annoying.
