What does limiter mean?
A limiter is a noun for something that puts a ceiling on a quantity, rate, level, or range. In electronics and music, the term usually refers to a device that clips or constrains a signal before it exceeds a safe or intended level. A speed limiter is the familiar road example, while a rate limiter controls how quickly a system can process or transmit data. Figuratively, a limiter may be a rule, budget, or other constraint that prevents an activity from growing without bound. The word is often more specific than limit and more technical than constraint: it suggests an active mechanism or rule that enforces a boundary. A limiter does not necessarily prevent all excess; it keeps a process within a specified operating range.
nounA device, mechanism, or rule that restricts something to a specified amount, rate, level, or range. The term also refers figuratively to a constraint that limits an activity or process.
- A device or mechanism that prevents a quantity, rate, signal level, or range from exceeding a specified limit.
- A rule, budget, or other control that restricts the scale or scope of an activity.
- Informally, a person who tries to restrain the behaviour or actions of others.
"The compressor and limiter kept the mix from clipping."
"The compressor and limiter kept the mix from clipping."
"The budget was the main limiter on the project's scope."
The plural is used when referring to multiple devices, controls, or constraints.
"The engineers added limiters to prevent excessive current and temperature."
In music, a limiter is the last line of defence against a mix becoming excessively loud or clipping into distortion.

Where does limiter come from?
Limiter was formed in English from limit plus the agentive suffix -er, meaning “one who or that which limits.” The word limit comes through Old French limite from Latin limitem, the accusative of limes, meaning “boundary” or “road.” The same Latin root underlies related forms such as limited, limitation, and delimiter.
How limiter is actually used
Primarily a noun. In technical contexts it denotes an active device or control that enforces a ceiling, while in general use it can refer figuratively to any firm constraint.
Easily confused with limiter
A limiter restricts a value or rate, whereas a delimiter marks the boundary between data or other elements.
