4.2.2.3. Mid/Side mode switch
Mid/Side (M/S) is an alternate mode to regular Stereo. This 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 covers the edges of that same image.
When you make adjustments in the Mid channel, this is perceived in the centered image of
the stereo spectrum (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 you 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 result in a more spacious
(wider) stereo sound.
In M/S mode, the controls corresponding to the Left will affect the Mid channel, while the
controls corresponding to the Right will affect the Side channel.
4.2.2.4. Auto Gain switch
This switch activates Auto Gain, which preserves the original audio volume after the
changes made by the EQ settings, this way preventing drastic changes (either boost or cut)
in volume. In mono instances, the Auto Gain switch is positioned on the left side panel.
It's a fact that, for our brains, louder is always better. Also, EQ is more effective when cutting
(attenuating), but attenuating frequency bands leads to power loss, which may trick our
hearing and lead us to increase volume and lose perception.
In that context, the auto-gain function may help us make sure that the chosen settings are
indeed better. With auto-gain, you appreciate cutting way more, as it doesn't come with
the frustration of power loss. You may really hear a different balance, as loudness is being
automatically compensated.
4.2.2.5. Link Channels switch
This switch links both channels, which means that the values of each channel mirror those
of the other channel. This way, when you edit ANY of the two channels, the other one
changes in exactly the same way. By default, the switch is on, which means that the two
channels are linked. To unlink, just click it and the Link button will turn off.
When link is off, each channel becomes independent, allowing you to set different values.
