How can you play audio without knowing these 56 professional audio evaluation terms!

　　1. Wide sound

　　Wide frequency band, small distortion, long linearity, large dynamic range, and relatively uniform distribution, prominent energy in the middle and low frequency bands, appropriate reverberation sound ratio, wide range of sound, fullness and comfort in listening.

　　2. Narrow voice (narrow)

　　The high and low frequencies are lacking, the frequency band is not wide, the reverberation is too short, and the intermediate frequency is too prominent. Narrow is the opposite of wide sound.

　　3. The sound is bright (loud and bright)

　　In evaluation, it is sometimes called brightness or brightness. In the entire sound range, the bass and midrange are moderate, the treble energy is sufficient, and there are rich harmonics and a slow decay process in the harmonics. At the same time, the reverberation sound ratio is appropriate, the distortion is small, and the transient response is good. Brightness is a prerequisite for improving clarity and intelligibility. The brightness is good, and listening to the sound will give people a sense of intimacy and activity, it sounds effortless, and the tone is bright and prominent.

　　4. The sound is dark

　　This is a response to the lack of high frequency and medium and high frequency, especially at 5000-6000 Hz and above, there is a significant decline, the sound conditions of the recording studio or listening room are poor, and the reverberation time of the medium and high frequency is short, and the sound will be dark in hearing. Matte and dull. Dark is the opposite of light.

　　5. The sound is thick

　　The sound is thick and powerful, the bass is full, the treble is not lacking, there is a certain brightness, and the low-frequency and mid-low frequency energy is strong, especially the 200-500 Hz sound. During recording and playback, the peak amplitude modulation of the volume meter is not necessarily very high, but the loudness is relatively large. If combined with the requirements of the picture in the film and television, the microphone is properly handled to be closer, which can give people a very close-range sound and a thick feeling. Thick Some units are called "thick".

　　6. Thin voice

　　Thin tone, lack of strength, poor resonance, less reverberation, low average sound energy level, lack of low frequency and mid frequency, the whole frequency response is too much attenuation below 300-500 Hz, there will be a thin feeling. Some units are called "single", which is the antonym of thick.

　　7. The sound is round (mellow)

　　The frequency band is wide, the sound quality is pure, the distortion is very small, there is a certain strength and brightness, the bass is not muddy, the midrange is not hard, the treble is not hairy, the transient response is good, the ratio of reverberation sound to direct sound, reverberation characteristics, and time are all relatively Appropriate, in the hearing sense: full, bright, clear, high fidelity.
