deemphasizer
This term is primarily used in technical contexts, specifically within telecommunications and signal processing. It refers to a circuit or device that reverses the process of pre-emphasis to restore the original frequency balance of an audio signal. It is a highly specialized term and is rarely used in general conversation.
Because it describes a specific piece of hardware or a functional block in a system, it is treated as a standard countable noun. It is almost always paired with its counterpart, the pre-emphasizer, to describe a complete signal chain.
