Is bit perfect reading necessary? It’s so many samples per second, 44100 to be precise, than one bit error once in a while cannot be noticed.

And it’s not like audio is actually high fidelity. Any DAC will introduce a lot of errors. And the original recordings are not perfect either. Microphones, loud speakers, amplifiers, that’s a lot more errors than one wrong bit too.

I imagine that a bit flip in the most significant bit could cause an unpleasant pop.

I'm not sure a loud speaker can produce a pop so quickly.

Here are some examples to listen to:

So I was wrong, it’s very loud.

A bit flip at the most significant bit is a one cycle 22.05kHz pulse - so yes you almost certainly wouldn't hear it even if the speaker could reproduce it.

You would totally hear it, as a small click. I had a bug in some audio software I was working with that did almost exactly this, and it sounded terrible.
