110 Chapter 10 Plug-in Enhancements

Â Threshold: Determines the lowest level that a side chain signal must attain before it

begins to reduce the (music mix) output level by the amount set with the Intensity

slider. If the side chain signal level doesn’t reach the threshold, the (music mix) track

volume is not affected.

Â Attack: Controls how quickly the volume is reduced. If you want the (music mix)

signal to be gently faded out, set this slider to a high value. This value also controls

whether or not the volume is reduced before the threshold is reached—the earlier

this occurs, the more latency is introduced. It should be noted that this only works if

the ducking signal is not “live” (in other words, the ducking signal must be an

existing recording): Logic needs to analyze the signal level before it is played back,

to anticipate the point where ducking begins.

Â Hold: Determines the duration that the (music mix) track volume is reduced for. This

control avoids a chattering effect that can be caused by a rapidly changing sidechain

level. If the sidechain level hovers around the threshold value, rather than clearly

exceeding or falling short of it, set the Hold parameter to a high value to compensate

for rapid volume reductions.

Â Release: Controls how quickly the volume returns to the original level. Set to a high

value if you want the music mix to slowly fade up after the announcement.

New Speech Enhancer Plug-in

Logic Pro 7.2 includes the new Speech Enhancer plug-in. This plug-in is designed to

improve speech recordings made with your computer’s internal microphone (if

applicable). It combines denoising, advanced microphone frequency remodeling and

multiband compression.

The plug-in offers the following controls:

Â Denoise: The value of this slider determines your estimation of the noise floor in your

recording, and therefore, how much noise should be eliminated. Settings towards

100 dB allow more noise to pass. Settings towards 0 dB will increasingly suppress

background noise, but will increase artifacts.
