and levelers work in such a way as to sound very natural, letting the character of the sound change with the different levels but still maintaining a predictable and usable dynamic range. A leveler is different from a compressor in that the ratio and threshold are controlled with a single control. Levelers sometimes feature only an overall gain and peak level control (aka normalization control) on particular models to more accurately and subtly manage peak volume.
