I said, there isn't much that isn't already optimal.

There was a time when linear PCM was considered optimal.


PCM was probably thought to be optimal in terms of bit rate for about
30 minutes between the time when the issue was first considered to the
time when someone thought up differential modulation - because
differential modulation is such an obvious solution to compress PCM
audio.

Try again, Silky Baby.

The adoption of DAB was the most incompetent technical
decision ever made in the history of UK broadcasting:
