midspectrum

Midspectrum is a general term used to describe the middle portion of a spectrum in various disciplines. It does not denote a single, fixed range; the exact boundaries depend on the field and application.

In optics and color science, the mid-spectrum typically refers to middle-wavelength visible light, commonly around 500 to 600 nanometers, corresponding roughly to green through orange. This range influences color rendering and perception and is contrasted with near-ultraviolet/near-infrared and the more extreme ends of the spectrum.

In acoustics, the mid-spectrum or midrange encompasses frequencies roughly from 300 Hz up to 3 kHz, though definitions vary. These frequencies carry much of the body and clarity of sounds, including speech intelligibility and most musical content, and are often the focus of equalization in audio systems.

In spectroscopy and analytical instrumentation, the mid-spectrum can denote the portion of the spectrum between the low-frequency/long-wavelength region and the high-frequency/short-wavelength region. Detectors and signal processing approaches may differ for mid-spectrum signals relative to extremes.

In data visualization and signal processing, “mid-spectrum” might describe mid-tones or mid-frequency components in a signal, which contribute to perceived balance and smoothness.
