Filter out Xing/LAME info frames, rather than letting them go to the mp3 decoder as if they were audio frames. Fixes the 1152-sample zero pad at start of some decoded mp3 files (distinct from decoder delay). The logic here is based on the madplay code.

Chris@235 1 # Sonic Annotator's summary method integrates the values across
Chris@235 2 # time. If an output lacks duration for its features, each feature is
Chris@235 3 # considered to extend until the timestamp of the following feature,
Chris@235 4 # and the final feature is considered to extend until the end of the
Chris@235 5 # input or the last-ending output, whichever is later.
Chris@235 6 #
Chris@235 7 # The curve-vsr output is therefore considered to have 9 values (0.0
Chris@235 8 # to 0.8) that span 0.75 seconds each, followed by one value (0.9)
Chris@235 9 # that spans the 3 seconds from 6.75 to 9.75 where the final output of
Chris@235 10 # the plugin ends (that's the notes-regions output).
Chris@235 11 #
Chris@235 12 # Since the values from this output are already sorted and are
Chris@235 13 # distinct, the integrated median is just whatever is in effect at
Chris@235 14 # time 9.75 / 2.0 = 4.875. This value is 0.6.
