Getting the start frame of an audio strip using python?

hi everyone.

i’m currently working on a blender script that handles audio files and wonder if there is a way of getting the start frame of an audio strip (in the sequencer) using python. i have done some searching in the API docs but couldn’t find any useful info. any help would be greatly appreciated.
