And I say it would be better to see 24-bit / 192 kHz compressed
audio than 16-bit / 44.1 kHz uncompressed audio, and the latter
would still require a higher bit rate than the former.

That would be an interesting discussion by itself. At what bitrate
will AAC actually sound better than "cd standard", using proper source
material of course.


It is an interesting question, but it's difficult to say, isn't it.

But you don't have to limit it to just 24-bit/192kHz, because the simplest
improvement would be to move from 16-bit to 24-bit, which shouldn't require
much of an increase in bit rate at all, because the same frequency
components would be audible, so it's just a matter of encoding those
frequency components more accurately.

Increasing the sampling frequency would require a greater increase in bit
rate, because there'd be more frequency components that would need to be
encoded. One problem though is that I'd imagine that all the audio codecs
have been tuned for 44.1/48kHz and I doubt there's been much work tuning
them for higher sampling rates bcause there's not much demand for it at the
moment.
