The center frequency controls the frequencies affected. The bandwidth (which is inversely related to Q) the range of frequencies affected. Parametric equalizers are capable of making much more precise adjustments to the sound than other equalizers and are commonly used in sound recording and live sound reinforcement.
The sound of a bullet entering a person from a close distance may sound nothing like the sound designed in the above example, but since very few people are aware of how such a thing actually sounds, the job of designing the effect is mainly an issue of creating a conjectural sound which feeds the audience's expectations while still suspending ...
The frequency range often specified for audio components is between 20 Hz to 20 kHz, which broadly reflects the human hearing range. Well-designed solid-state amplifiers and CD players may have a frequency response that varies by only 0.2 dB between 20 Hz to 20 kHz. [ 4 ]
Most other aspects of audio for moving pictures occur during the post-production phase, everything is done after filming. This also may include sound design or the creation of sound effects, which can occur during pre-production, production, or post-production. This applies to television, cinema and commercials.
In an amplifier, a presence control boosts the upper mid-range frequencies to make the sounds of voices and instruments with similar tonal ranges seem more "present". [1]On television production studio's sound desk, there can be several presence controls, for several different, switchable, frequencies. [2]
One way of stretching the length of a signal without affecting the pitch is to build a phase vocoder after Flanagan, Golden, and Portnoff.. Basic steps: compute the instantaneous frequency/amplitude relationship of the signal using the STFT, which is the discrete Fourier transform of a short, overlapping and smoothly windowed block of samples;

Joseph S. Wisniewski writes that "green noise" is marketed by producers of ambient sound effects recordings as "the background noise of the world". It simulates the spectra of natural settings, without human-made noises. It is similar to pink noise, but has more energy in the area of 500 Hz. [20]
