Logic Pro Stereo Spread
Stereo Spread is generally used when mastering. There are several ways to extend the
stereo base (or the perception of space), including using reverbs or other effects and
altering the signal phase. These options can sound good, but they can also weaken the
overall sound of your mix by ruining transient responses, for example.
Stereo Spread extends the stereo base by distributing a selectable number of frequency
bands from the middle frequency range to the left and right channels. This is done
alternately—middle frequencies to the left channel, middle frequencies to the right
channel, and so on. This greatly increases the perception of stereo width without
making the sound totally unnatural, especially when it is used on mono recordings.
Stereo Spread parameters
• Lower Intensity slider and field: Set the amount of stereo base extension for the lower
frequency bands.
• Upper Intensity slider and field: Set the amount of stereo base extension for the upper
frequency bands.
Note: When setting the Lower Int and Upper Int sliders, be aware that the stereo effect
is most apparent in the middle and higher frequencies. Distributing low frequencies
between the left and right speakers can significantly alter the energy of the overall mix.
Use low values for the Lower Int parameter and avoid setting the Lower Freq parameter
below 300 Hz.
• Graphic display: Shows the number of bands the signal is divided into and the effect
intensity in the upper and lower frequency bands. The upper section represents the
left channel. The lower section represents the right channel. The frequency scale
displays frequencies in ascending order, from left to right.
• Upper/Lower Frequency slider and fields: Determine the highest and lowest frequencies
that are redistributed in the stereo image.
• Order knob and field: Determine the number of frequency bands that the signal is
divided into. A value of 8 is usually sufficient for most tasks, but you can use up to
12 bands.
