An idealized and extreme smiley face curve shown using a 29-band graphic equalizer. A smiley face curve or mid scoop [1] in audio signal processing is a target frequency response curve characterized by boosted low and high frequencies coupled with reduced midrange frequency power.
An exciter (also called a harmonic exciter or aural exciter) is an audio signal processing technique used to enhance a signal by dynamic equalization, phase manipulation, harmonic synthesis of (usually) high frequency signals, and through the addition of subtle harmonic distortion. Dynamic equalization involves variation of the equalizer ...
For example, in Europe, for many years recordings required playback with a bass turnover setting of 250 to 300 Hz and a treble rolloff at 10,000 Hz ranging from 0 to −5 dB, or more. In the United States, practices varied and a tendency arose to use higher bass turnover frequencies, such as 500 Hz, as well as a greater treble rolloff such as ...
YouTube videos often have profanity bleeped or muted out as YouTube policy specifies that videos including profanities may be "demonetized" or stripped of ads. [10] Beginning in 2019, the bleep censor began to be more often used for censoring out words related to sensitive and contentious topics to evade algorithmic censorship online ...
The audible severity of modest intermodulation distortion is not well established. The result is a degree of "frequency mixing", albeit at a relatively low level. A full range driver may have reduced output at both ends of its frequency range, or a more severely limited frequency response, resulting in a more compromised sound.
For more than a dozen years, YouTube’s Coachella livestream has been contemporary music’s greatest showcase: a proving ground for superstars, rising and returning artists — all of whom know ...
Treble describes tones of high frequency or high pitch, ranging from 6 kHz to 20 kHz, [1] comprising the higher end of the human hearing range. In music, this corresponds to high notes. The treble clef is often used to notate such notes. [2] Treble sound is the counterpart to bass sound.
Later Fender amplifiers used a different presence control. The presence control on the 1975 Fender Super Twin did not modify the negative feedback loop, but was an active equalization circuit, controlling the 3.9 kHz frequency range. It had the ability to both amplify (boost) and attenuate (cut), unlike the earlier presence control.
