Tuneable

Tuneable is an adjective describing something that can be tuned—adjusted or calibrated to reach a desired state, pitch, or performance. The spelling tuneable is standard in British English; tunable is the more common form in American English and international usage.

In music, many instruments are tuneable, meaning their pitch can be adjusted to match a reference pitch or suit a performance. Tuning typically involves changing tension, length, or valve settings, and precise tuning can be maintained with locks, locks, or electronic tuners.

In science and engineering, the term applies to devices whose output can be varied in a controlled way. Examples include tunable lasers, tunable optical filters, and tunable oscillators, where frequency or wavelength is adjusted by changing physical parameters such as temperature, current, or cavity length, often under electronic control. Tunable components are essential in spectroscopy, communications, and instrumentation.

In computing and systems design, tunable parameters are variables that can be modified to optimize outcomes such as speed, energy use, or accuracy. The degree of tunability, or tunability, describes how readily a system can be adjusted, sometimes involving automated or adaptive strategies.

Etymology and usage notes: tuneable derives from tune plus -able; in practice, both spellings appear, with tuneable favored in British style guides and tunable in others. The concept contrasts with fixed or non-tunable components, which lack adjustable settings.
