In the “Soft” mode, limiting begins to occur at a level that is 3dB below the
actual limiter threshold setting. The transfer function at this point is relatively
soft. That is, the audio waveform is not abruptly limited, but is instead allowed to
slightly increase over an additional 3dB window until the ultimate limit threshold
is reached, whereupon no further amplitude increase is permitted.
Because of its behavior, the sound of the “Soft” function is less obvious and
has a “spongy” sound when in operation. It is also less precise as a true limiter
until the ultimate limit threshold (the setting of the band threshold) is finally
reached. We’ve provided the “soft” setting primarily as a sound manipulation tool.
