A recording of my piece is unfortunately not available any longer, but here is the link to the very interesting audio file that I was lucky to receive from freesound.org's random algorithm:
I have actually done a similar thing a couple of years ago when composing for wind band. Of course, I could not include the sample in its raw form since I could not use electronics, but instead I used it as a first seed of inspiration and tried to incorporate different features of the given audio file into the final composition, such as rhythms, melodic contours of the dialogs etc.
Yes, this is indeed all the requirements. While most of the challenges had some sort of technical obstacle, as a contrast, this is more open-ended and has more of an artistic obstacle.
