HD Final Limiter (Basic Tab)

The HD channel employs an advanced look-ahead limiter to provide absolute precision peak control. This limiter
h as been designed to minimize processing side-effects like IM distortion, which are usually associated with limiters
of this type. This allows this limiter to sound extremely transparent.
This type of peak controller is used instead of a clipper because it does not generate the same high levels of
harmonic distortion as a Clipper does. This di
b ecause the harmonics generated from the clipping action create added artifacts and workload in the encoder. These
are especially annoying at high frequencies.
There are tradeoffs in how each of these peak controllers sound when they
a clipper is pushed, the audio may sound edgier. This is from the added harmonic content. In contrast, the look-
ahead limiter will sound busier, or denser, when more limitin g is applied.
