Gain

Stereo gain and pan utility with level metering. Uses the built-in GUI.

Source: examples/truce-example-gain/.

#What it demonstrates

• Exponentially smoothed parameters (smooth = "exp(5)")
• Equal-power pan law using cos/sin on a quarter-circle angle
• Peak metering via ProcessContext::set_meter
• Grid layout with knobs, XY pad, and stereo meter

#Parameters

Name	Range	Unit	Description
Gain	-60 to +6	dB	Output level
Pan	-1 to +1	pan	Stereo balance

#GUI variants

The same gain plugin is implemented with four different GUI backends — compare them to see how each framework handles the same layout:

• gain (this one) — built-in grid layout
• gain-egui — egui immediate-mode widgets
• gain-iced — iced retained-mode widgets
• gain-slint — declarative .slint markup
