Hi,
This is a great forum and I have been reading in it for a couple of months with interest. I thank you all for the wealth of information contained here.
I am a philosopher. I teach a philosophy of science course! I also have a background in music. This is my first post.
I noticed a flutter on some tracks streaming on Amazon Music and other services about three years ago and wondered why this was happening. I saw some references to "audible watermarking." I didn't use the service very much for a while but started again recently and it didn't take me long to find more examples. I thought I would check on this forum and I saw this thread. Here are my examples:
(1) Mozart Requiem, Karl Böhm, DG recording, track 1, starting around 1:00 in. Using Amazon Music app for PC, Audacity to record the sound coming through my computer.

The track on Amazon Music:
If I go to YouTube, I don't hear the same flutter. (Starting at 0:57.) I don't have the CD to compare.
(2) Flutter on the second note, and more, of the trombone solo of the Tuba mirum of the same recording.

Compare with YouTube:
(3) Third example: The Neville Marriner recording of Mozart's Gran Partita, Adagio (3rd mvt.), around 3:00 in.

You can find this on YouTube too, but in this case I played (what I think is) the same recording on spotify (web interface), and this is what I got:

No flutter. (I don't have the CD of this one either.)
I'm wondering what could cause this. If this has been discussed to death already, I apologize for the duplication. I did do a search, and this is the closest I found.
Thanks,
Mark
