1 level plugin by thomas <thomas@apestaart.org>
4 - running time since last EOS/start
9 over the given interval.
11 This is useful for a VU meter display and for plotting out the signal graph.
12 The VU meter can either display RMS, or display immediate peak level and
13 have the falloff decaying peak level displayed as a line.
15 The interval for signal emission, ttl of decay peak, and falloff of decay peak
18 The element only takes unsigned data in; it could be extended to signed as
19 well, if separate fast chain functions are made that displaces the incoming
20 data to its midpoint (ie, 0,65535 should be mapped to -32768, 32767)
22 There are two demo apps, apps and plot. apps will create some GTK sliders
23 to display the volume. plot will output data readable by gnuplot.
25 Here is a sample plot script to plot output of the plot command that was
31 plot 'plot.dat' using 1:2 title 'L RMS' with lines, \
32 'plot.dat' using 1:3 title 'L peak' with lines, \
33 'plot.dat' using 1:4 title 'L decay' with lines
35 plot 'plot.dat' using 1:5 title 'R RMS' with lines, \
36 'plot.dat' using 1:6 title 'R peak' with lines, \
37 'plot.dat' using 1:7 title 'R decay' with lines
