   A half second is a half second, but canceling the echo does help   
   intelligibility by removing some noise from the signal. Time-of-flight   
   isn't the only issue.

   Excessive reverb is a bad thing. Done correctly, reverb adds a sense of   
   presence without interfering with intelligibility.

   True, but these tools are useful for lots of other real-world problems.
