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.

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).

13 # seconds each (i.e. the same durations as the first 9) each with the

14 # same value, 0.9.
