GRAPHS & METERING
Audio Level
Metering
Near the top of this Web
interface page you’ll find
an audio level metering
utility with significantly
greater resolution than
the 10-segment front-
panel LED or its on-screen counterpart that headlines every
Web interface page. Levels for both the
Left
and
Right
channels
and the
L+R
/
L–R
stereo sum/difference are shown with linear-
dB scaling.
The full-scale, 0dB point corresponds to ±75kHz monaural ana-
log-FM deviation, or nominal full-scale modulation of any HD
Radio digital channel. See Page 13 for other metering caveats.
Keep in mind that this metering applies solely to the service
that you have selected for listening. If you are listening to FM,
that’s the audio you see. If you have punched-up HD3 on the
Now Playing
page, then that’s what you’re looking at. This may
seem a no-brainer, but it has implications that we’ll soon reveal.
Histograms

Web interface page pre-
sents two ‘rolling histo-
grams,’ or constantly-
updated plots-over-time
