4.5.4. Mid/Side mode

Mid/Side mode is a highly effective way of making adjustments to the spacialization of a

mix or master. In Mid/Side, the Mid channel is the center of a stereo image, while the Side

channel is the edges of that same image. When we make adjustments in the Mid channel,

this is perceived in centered image of the stereo spectrum (we can think of it as the mono

compatible image). For example, a boost in the Mid channel will make the sound more

“mono” (both channels will sound more equal).

On the other hand, when we make adjustments in the side channel, this will have an impact

on the width of the stereo image, and a boost in this channel will be perceived as a more

spacious (wider) stereo sound.

For M/S purposes, the controls on the left side will affect the Mid channel, while the controls

on the right side will affect the Side channel. Also, when in M/S mode the VU meters show

the output level of the Mid for the first one (Left), and the output level of the Side for the

second one (Right).

While we're at it, there is a simple test that you can run to check the difference between

stereo, Dual Mono and mid/side processing. Here are the steps to do it:

The lower right section of the TridA control panel, showing

the Output Trim knobs, and above them the two switches

that control the behavior of the plug-in in Double Channel:

the Stereo Mode and the Stereo Link.
