Hi, Fons!
Will you be so kind to point me to publically available explanation of
k14/k20 sense/motivation?
There is a link to Bob Katz' pages in the README. The K-meters indicate two values: an RMS one (the
coloured bar), and digital peak value (the white
dot). These are two independent values: the dot
is *not* the peak value of the bar as it is with
most meters. They will indicate the same value
for a continuous sine wave.
For typical music signals the peak indication will
be higher than the RMS one, and that is why the dB
scale (which applies to the RMS indication) is offset.
The only difference between the k20 and k14 meters is
this offset of the scale, they are the same meter
otherwise.
The k14 is used for music that is compressed, so it
can have a lower peak/RMS ratio, and thus a higher
average RMS level.
...your explanation is sufficient for me now. Fons, thanks!
