Adding extended targets to an equalizer expands its range of influence. Imagine a standard equalizer adjusting only the bass and treble frequencies. An extended target capability could allow control over a much wider spectrum, including mid-range frequencies or even very specific, narrow frequency bands. This fine-grained control is often visualized and manipulated through a graphical interface, with sliders or nodes representing individual frequencies and their respective gain levels.
Enhanced precision in sound shaping offers significant advantages in various audio applications. From music production and mastering, where subtle adjustments can drastically alter the final mix, to live sound reinforcement, where compensating for venue acoustics is crucial, this broader control delivers a more tailored and optimized audio experience. The historical progression of equalizers reveals a trend towards greater complexity and control, driven by the demand for more accurate and sophisticated sound manipulation tools. This increased granularity directly correlates with the evolution of digital signal processing, which allows for more complex calculations and filtering capabilities than traditional analog methods.
