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.
Equalization, or simply EQ, in sound recording and reproduction is the process of adjusting the volume of different frequency bands within an audio signal. The circuit or equipment used to achieve this is called an equalizer. [1] [2] Most hi-fi equipment uses relatively simple filters to make bass and treble adjustments. Graphic and parametric ...
For example, the RIAA pre-emphasis in the popular Neumann SAB 74B equalizer applies a second-order roll off at 49.9 kHz, implemented by a Butterworth (maximally flat) active filter, plus an additional pole at 482 kHz. [2] This cannot be compensated for by a simple zero even if it were necessary, and in any case, other amplifiers will differ.

The Guitar Rig environment is a modular system, providing capabilities for multiple amplifiers, effects pedals and rack mounted hardware.Primarily designed for electric guitar and bass, the software uses amplifier modeling to allow real-time digital signal processing in both standalone and DAW environments via plug-in (VST/DXi/RTAS/AU).
In signal processing, control theory, electronics, and mathematics, overshoot is the occurrence of a signal or function exceeding its target. Undershoot is the same phenomenon in the opposite direction.
This couples the real and imaginary part of the baseband description, thereby adding structure. This immediately implies that either the real or the imaginary part are enough to describe an analytical signal. By measuring both in a noisy setting, one has a redundancy that can be used to better reconstruct the original signal.
