Purely electronic devices may emulate the response of the needle they are VU-meters in as much as they respect the standard. In effect, the scale ranges from −20 VU to +3 VU, with −3 VU right in the middle.
The meter was designed not to measure the signal, but to let users aim the signal level to a target level of 0 VU (sometimes labelled 100%), so it is not important that the device is non-linear and imprecise for low levels. Does anyone have the program needed to mod the analog VU meters The program: VUEditorGUI.exe. '0 VU is equal to +4 dBu, or 1.228 volts RMS, a power of about 2.5 milliwatts when applied across a 600-ohm load. How do I edit / make my own analog VU meter for foobar2000 I know there is a specific editor, but all the links I found were directed to the currently dead Google Sites page. So, the green units on the pic are the actual dB units? Is that what you prefer to see as opposed to the sort of mysterious (to me) VU units? FWIW from the Wikipedia: Now if you can get through THAT gobbly-gook explanation my hat is off to you, haha.
It's hard to know what I'm really looking at as I'm so used to dB units, so I was eye-ballling the differences with the VU meter and 'Enhanced Spectrum' Foobar plugin's peak readings and your Dejavu meter ( mod) and at -15db meter preamp it seemed to be around 3 units off from the dB peaks, but as those units apparently differ around 4 units (from what I was able to find out) that may be OK. Hiccup: I wasn't familiar with the concept of VU units vs dB so I had to do some reading on that.
