Details:
One of the clearest captures of a Starlink train to date (the L14, the latest one), both in video and audio format (the first I've ever recorded).
The video/audio can be found here on my Youtube channel: https://www.youtube.com/watch?v=CKFo5nhWhdQ
A very peculiar sound, almost 'spectral', with interesting undertones. Notice the peaks, spaced equally on every diagonal track.
The audio is actually longer than the time represented in the image, so the green bar will star moving 6 seconds after the start, and will stop moving 30 seconds before the end.
Pay attention to all the various tune-changes as the video plays forward, especially in the second half. They are a clear indicator of the movement of an object (in this case, Starlink satellites), via Doppler shift.
The Space Station produces the same sounds, albeit they are usually stronger, due to the bigger reflection area generated by the structure of the ISS.
