sound_bake by script : unsupported audio format error I can't get the sound_bake function to work by script while it works fine from the menu (Unsupported audio format). Any idea ? 

I have no backslashes in the path and my blender build includes ffmpeg... so I am out of idea... ?

Especially since it works when I bake manually from the menu with the same file !

Here's the piece of code :

# get the path from the sequencer
bpy.context.area.type = "SEQUENCE_EDITOR"
for s in bpy.context.scene.sequence_editor.sequences:
    if s.type == 'SOUND':
        file_path = s.filepath

# insert keyframe to the VU of the 3d object        
bpy.context.area.type = "VIEW_3D"
bpy.context.scene.objects.active = bpy.data.objects['vu']

bpy.ops.anim.keyframe_insert_menu(type = "Scaling")
bpy.context.active_object.animation_data.action.fcurves[0].lock = True
bpy.context.active_object.animation_data.action.fcurves[1].lock = True

# bake
bpy.context.area.type = "GRAPH_EDITOR"
bpy.ops.graph.sound_bake(filepath=file_path, low=(0), high=(2000))


Thanks for reading !
So here's the trick : Blender internally use relative paths but provides a function to convert it to 'absolute'.

In my case, I just had to add the line :

absolute_path = bpy.path.abspath(s.file_path) 


Thanks again Simon
