-level plugin by thomas <thomas@apestaart.org>
-
-this plugin signals:
- - running time since last EOS/start
- - channel
- - RMS level
- - peak level
- - decaying peak level
-over the given interval.
-
-This is useful for a VU meter display and for plotting out the signal graph.
-The VU meter can either display RMS, or display immediate peak level and
-have the falloff decaying peak level displayed as a line.
-
-The interval for signal emission, ttl of decay peak, and falloff of decay peak
-can all be set.
-
-The element only takes unsigned data in; it could be extended to signed as
-well, if separate fast chain functions are made that displaces the incoming
-data to its midpoint (ie, 0,65535 should be mapped to -32768, 32767)
-
-There are two demo apps, apps and plot. apps will create some GTK sliders
-to display the volume. plot will output data readable by gnuplot.
-
-Here is a sample plot script to plot output of the plot command that was
-stored to plot.dat
-
-set xlabel "Seconds"
-set ylabel "dB"
-set yrange [-60:0]
-plot 'plot.dat' using 1:2 title 'L RMS' with lines, \
- 'plot.dat' using 1:3 title 'L peak' with lines, \
- 'plot.dat' using 1:4 title 'L decay' with lines
-
-plot 'plot.dat' using 1:5 title 'R RMS' with lines, \
- 'plot.dat' using 1:6 title 'R peak' with lines, \
- 'plot.dat' using 1:7 title 'R decay' with lines
