Factors: - Quality of audio equipment - The experience of the listener - The nature of the audio

It’s quite obvious that the average listener listening to a 128kbps podcast stream is not the issue here. Nor is the average listener listening to a 320kbps stream of a loud, noisy pop/rock album.

But there are certain types of music where it’s much more apparent. I have a trained ear and so I can’t speak for everyone. There are certain types of music where I can’t tell the difference. But some classical piano albums on Spotify sound terrible to me. The artifacts of the conpression are more obvious on sensitive, detailed music.

All this to say that a random seection of people failing an online test to some random audio isn’t a comprehensive answer to this question.
