aes31-adl-composer's Issues

adjust input of function

the edits adjust input of function might need a second look at, see example of edits from python version

# Edits are defined as a list of dicts with the following attributes:
# - start    [float]    start time
# - end      [float]    end time
# - filename [string]   audio filename
# - path     [string]   path to audio file
# - label    [string]   label for edit

Failed when importing in SADiE

When importing in SADiE (by one of the radio producers) it pops up with this modal

but then it says when selecting ok, it just says failed

Take the Originator Reference (UUID) for each source in source index

Is your feature request related to a problem? Please describe.

Deviating away from the original ADL code from Chris Baume.
Since our use case is not limited to just localhost files, it would be good to be able to pass in the originator reference, which is the first thing that apparently SaDiE looks for.

Describe the solution you'd like
Option to pass in originator reference.

Compare ADL output from python module against node module output

It be good to run the python module, to get an ADL that can be used to write a test to check agains the output of the refactored node module.
