User Manual

Side > Mid is similar to the Reversed option in Stereo mode. Here, the Side Channel is used
for detection and the Mid Channel will be compressed accordingly.
Mid > Side is a variation of the above, this time using the Mid Channel for detection, and
compressing the Side Channel.

♪: Advanced Detection Mode needs two channels. Therefore, this control is absent (it doesn't exist)
when the plug-in is instantiated in Mono tracks.
4.3.1.3. Mid/Side Mode
Mid/Side mode is a highly effective way of making adjustments to the spacialization of a
mix or master. This is done by analyzing phase coherence between left and right channels
and letting the processor work only on the "middle" or "edges" of a stereo field, instead of the
entire f field.
In Mid/Side, the Mid channel is the center of the 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 the 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.
4.3.1.4. Time Warp
This is where we can set the much talked “look-ahead” mode of detection, by applying
negative values (Snap).
We can also perform the exact opposite effect, and delay the detection by applying positive
values (Loose). This may allow some faster attack transients to "escape" detection, and
sound unaffected by compression.
By default, this control is positioned at 0, which means it will have no effect on detection.
Snap time (look-ahead) may go up to 5 milliseconds (-5.00) while Loose time may go up to
10 milliseconds (10.00).
