I think the K-14 system might be more to my own taste.
When trying to get an idea of how jkmeter 'reacts',
be careful when using 'canned' music. This evening
I compared two signals:
1. A broadcast from the BBC proms, relayed live on
Italian radio,
2. A piano recital recording which I made some
weeks ago, without any processing or gain
adjustments.
For both I adjusted gains so that the loudest parts
of the music would indicate between 0 and +3dB on
the jkmeter RMS level, i.e. the 'yellow' range.
This is how you would normally use such a meter.
For 1, the softest parts where at around -10 dB, and
the maximum DPL was -9.4 dB.
For 2, the softest parts where at around -20 dB, and
the maximum DPL was -3.9 dB.
This indicates that 1. was already being processed,
both manually (by the recording engineer gently
boosting softer parts - you'd expect more than 10
dB dynamics for Beethoven's first), and by peak
limiting (again not very intrusive, but essential
for broadcast).
