ABLM is a gain control which enables level matched and sample accurate AB comparison of FX chains.

Most DAWs can easily enable/disable (AB) single plug-in or even whole FX chains, but in most case there is an audible loudness difference between both cases. In order to compare the impact of a plugin chain objectively the loudness of the incoming signal should match with the loudness of outgoing signal.

Voxengo Elephant is a mastering limiter AAX, AudioUnit and VST plugin for professional sound and music production applications. The most remarkable feature of this signal limiter is its sonic transparency. Elephant brings sound limiting and loudness maximization without audible "fuzz" and "pumping” sonic artifacts.

Elephant is a highly competitive plugin for mastering applications: it features a variety of limiter modes that can be deeply customized, and a comprehensive set of level metering tools, including headroom estimation and K-system metering. Elephant's built-in linear-phase oversampling is an important element in achieving high-quality peak limiting and loudness maximization without inter-sample overshoots.
