Importing/loading sound file to scene via Python

[ezeuz]

Hi everyone, pretty new here. I got to read the documentation and honestly amazed at how well-documented everything is.

Tho, despite of that, I'm still unable to find a way to import sound/audio file. I guess it's due to the fact that in the GUI itself, adding sound is a multi-steps process, so I'm unable to directly find the relevant method.

If anyone got any tips, it'll be appreciated, thanks!

I managed to search a bit more, so turns out everything related to keyframe is defined as CTrack. It's just a matter of determining the type/attribute.

I will try to adapt the solution from this topic (it was about keyframing visibility): https://developers.maxon.net/forum/topic/13686/python-script-to-keyframe-visibility-of-object/3?_=1721442329144

With the new information regarding CTsound to refer to the sound special track: https://developers.maxon.net/docs/py/2024_0_0a/modules/c4d/C4DAtom/GeListNode/BaseList2D/CTrack/index.html?highlight=ctrack#c4d.CTrack

And maybe post the result once I figure it out.

Turns out it's really simple, the documentation using ID instead of DescID creates unnecessary confusion. I thought they meant to insert c4d.CTsound directly to CTrack, but you need to follow the previous examples to use DescID.

In any case, here you go:

def create_audio_track(self, path):
  """Add an audio track to the selected object"""
  # Define a new audio track (following the documentation)
  descId = c4d.DescID(c4d.DescLevel(c4d.CTsound, c4d.CTsound, 0))
  track = c4d.CTrack(op, descId)
  track[c4d.CID_SOUND_NAME] = path
  
  op.InsertTrackSorted(track)

Great to hear you've figured it out and thanks for sharing the solution with the community!
