How Does It Work?#

VU Meter monitors one incoming signal with a vintage-style analog needle, a segmented level bar, and live RMS / peak readouts.

Quick Overview#

• One monitor input and no outputs.
• Analog-style needle plus digital-style bar graph.
• Selectable response modes, peak hold, clear-peak button, and input gain trim.

Input#

Port	Type	What It Does
IN	Multi	Signal to monitor.

VU Meter has no outputs. It is meter-only.

Controls Reference#

Control	Values	Default	Behavior
Response	C, H, F	C	C uses classic RMS-style motion, H uses RMS needle with peak bar, and F uses faster peak-oriented motion for both.
HOLD	Off, On	On	Enables or disables peak hold.
CLR	Momentary		Clears the stored peak indicator.
Gain	0..2	1	Adjusts the monitored level before display conversion.

What You See#

• The analog needle shows the current response target.
• The segmented bar gives a quick at-a-glance level view.
• The peak indicator tracks the highest recent level.
• The readouts below the meter show live RMS and PK values in dBFS.

Usage Notes#

• C, H, and F trade smoother motion for faster peak visibility.
• Peak hold only affects the held peak indicator, not the live signal path.
• If detailed probe stats are unavailable, the module falls back to cable meter data for level updates.
