There is a link to Bob Katz' pages in the README. > And is there some probability you will add a k0 type? :-) Zero, it doesn't make any sense to do that. 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.
