So, an unofficially-official answer I got was that the audio on both the shuttle and ISS sounds the same as it did in 1980 because the infrastructure is basically the same as it was in 1980.
Video has been upgraded several times because nasa cares very much about the ability to see everything as clearly as possible. Audio hasn't really been upgraded because all that matters is telephone bandwidth for clear communication.
The mic that is used on both the shuttle and ISS is a Crown GLM that has been ruggedized and mounted to a box with the PTT and preamp circuitry inside. Take the tone of that mic and compress the living daylights out of it, then compand it, then bandwidth limit it several times, and you get what you hear on the ground.

besides, while technological improvements are likely easily within budget (), we might not necessarily want to hear everything going on up there in high resolution micro-detail (think of the gastro-intestinal ramifications of the diet)

thank goodness the technology doesn't exist to transmit olfactory impressions


oh no, there's another escapee from the commode

But not as much junk nor total items so that seems to make the US the worst polluter no?

Yeah, true, though the difference is small anyway. One man's satellite is another man's debris

Remember the rule, the wider the window the more dirt blows in. Keeping the bandwidth down to the bare minimum actually improves intelligibility in noisy environments. The audio is also processed to maximise intelligibility at the expense of what we would call "fidelity".
Amateur radio enthusiasts, especially those who participate in competitions, know the value of a good speech processor.

Thanks IMIX, great answer.

Yeah Don, I suppose the do it to make voices more "clear." It just sounds silly to me. Willing to bet NASA loves the retro sound.

We attract attention.

Why is NASA audio so bad?
