342 Chapter 11 Working with Audio Effects

There are three smoothing parameters that you can use to minimize the “glass-noise”

effect: Frequency smoothing, Time smoothing, and Level smoothing. Raising the

Frequency smoothing slider results in a smoother transition of denoising to the

neighboring frequencies. When the Denoiser recognizes that only noise is present in a

certain frequency band, the higher the Frequency Smoothing parameter is set, the

more it will also change the neighboring frequency bands to avoid glass noise.

By adjusting the Time smoothing slider, you can set the amount of time the Denoiser

takes to reach maximum noise reduction. By adjusting the Level smoothing slider, you

can set a factor for a smoother transition between adjacent volume levels. When the

Denoiser recognizes that only noise is present in a certain volume range, the higher the

Transition smoothing parameter is set, the more it will also change similar level values

to avoid glass noise.

Stereo Spread

The Stereo Spread plug-in is a useful effect for sound design or audio clean-up. It

enhances the perception of stereo by extending the stereo base. Some stereo

enhancing algorithms function by changing the phase of the signal, which can distort

your mix and produce unpredictable results. Instead, the Stereo Spread plug-in extends

the stereo base by distributing a selectable number of bands in the middle frequency

range alternately left and right. This increases the perception of stereo without causing

unnatural-sounding distortion of the mix.

The main parameters of the Stereo Spread plug-in are Order, Upper Intensity (Upper Int.),

and Lower Intensity (Lower Int.). The Order parameter determines number of frequency

bands into which the signal is divided. The Upper Intensity parameter controls the

intensity of the base extension of the upper frequency bands. The Lower Intensity

parameter controls the intensity of the base extension of the lower frequency bands.

Human beings perceive stereo placement of sounds mainly in the middle and high

frequencies. If very low frequencies are distributed between the left and right speakers,

the energy distribution for both speakers will be significantly worse. Therefore, it is

always best to select a lower intensity setting for the lower frequency bands, and avoid

setting the Lower Freq. below 300 Hz.
