A jump from the lowest semitone to the highest semitone in one octave doubles the frequency (for example, the fifth A is 440 Hz and the sixth A is 880 Hz). The frequency of a pitch is derived by multiplying (ascending) or dividing (descending) the frequency of the previous pitch by the twelfth root of two (approximately 1.059463).
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.
The lateral-cut NAB curve was remarkably similar to the NBC Orthacoustic curve, which evolved from practices within the National Broadcasting Company since the mid-1930s. Empirically, and not by any formula, the bass end of the audio spectrum below 100 Hz could be boosted somewhat to override system hum and turntable rumble noises.

Bass (/ b eɪ s / BAYSS) (also called bottom end) [2] describes tones of low (also called "deep") frequency, pitch and range from 16 to 250 Hz (C 0 to middle C 4) [3] and bass instruments that produce tones in the low-pitched range C 2-C 4. They belong to different families of instruments and can cover a wide range of musical roles. Since ...
Tuning machines (with spiral metal worm gears) are mounted on the back of the headstock on the bass guitar neck. The standard design for the electric bass guitar has four strings, tuned E, A, D and G, in fourths such that the open highest string, G, is an eleventh (an octave and a fourth) below middle C, making the tuning of all four strings the same as that of the double bass (E 1 –A 1 –D ...
As shown in the bass management block diagram, a 5.1-channel audio system consists of five discrete, full-range main channels (front left, center, front right, surround left, and surround right), plus a band-limited low-frequency effects (LFE) channel for added bass (this corresponds to the .1).
