VU meter

(for Vista and Win7)

A VU meter source plugin and a config using Samurize progress bars. Note: this plugin has now been superseded by the far more advanced SpecGP. I posted it here if you need a simple VU meter, or if you want the sample configs.

Digital VU meter

The color version is meant to look like a LED VU meter: neutral zone with green LEDs, yellow warning zone and red clipping zone. I couldn't think of a way to get this effect with a single progress bar per channel, so I resorted to the trick of using 3 separate progress bars linked by meter math to a single reference. It works, but I wish progress bars in Samurize could display color zones, not just a start-to-end gradient (SpecGP does color zones).

Analog VU meter

Parameters

Channel	0=L, 1=R, up to 8 channels (5.1, 7.1, etc)
Use system volume	1=plugin responds to changes in system vol. level (moving a volume slider or muting); 0=no response
Decay	Smooths out animation by clamping down rapid changes. This is a fraction of the full range of motion allowed to happen between two frames. 1.0=full range of motion, 0.05=any change limited to 5% of the full range
Gain	Boost values for display (1.0=no boost)
Untaper	(for SystemVolume) Win7 uses a log volume scale ("taper"). Set your vol. slider to 50% and adjust this value so that the SystemVolume function returns 50% (1.0=no correction)

Functions

ChannelPeak	peak value
ChannelCount	number of available channels
HardwareFlags	the sum of hardware support flags: 01=hardware volume, 02=hardware mute, 04=hardware peak meters
VolumeRange	hardware volume range; typical values: min=-96dB, max=0db, increment=0.035dB
SystemVolume	system volume setting (%)
SystemMute	system mute setting (0=off, 1=on)
