I'm able to create an audio and midi track with create_audio_track and create_midi_track, and I'm also able to create an empty midi clip to a midi track, but am I somehow able to load a sound file to an audio track?
Well, since nobody's answered the question I'll deduce that it isn't, which is a shame. I stumbled upon a story from 2009 and it mentioned that it wasn't possible. Six years has gone from that and it still isn't possible! Strange.
