Audio VU meter

The VU meter is shown on the right of the player screen. It shows peak and integrated audio levels in the dB scale as the master output for all the available audio channels mixed together. The scale has the following areas for the instant level display (the values here are in the user’s scale):

  • Green – below 0 dB

  • Yellow – 0 to 4 dB

  • Red – above 4 dB

In addition, there are integrated (1000 ms) levels shown with the white bars. At the top of the scale, there is an additional color indicator. It shows the integrated status of the signal (during approximately last 1.5 seconds). The following states are indicated (note, the value here is absolute, in dBFS, or dB Full Scale):

  • Black – digital silence (below -120 dBFS)

  • Green – signal below -6 dBFS

  • Red – signal above -6 dBFS

At the bottom of the scale there are two speaker buttons which you can use to mute audio channel(s). To mute an individual left/right audio channel, press the corresponding speaker button or both buttons to mute both audio channels simultaneously.

Note
 The typical parameter values in broadcasting are -21 dB for NTSC and -18 dB for PAL.
