"No one" as long as you're talking about computer software only; I
wasn't. Sorry if that wasn't clear. It's my understanding that quite a
lot of digital audio hardware, such as Yamaha's digital mixers, uses
24-bit integer calculations for most (all?) of the signal path. The
results are generally considered to be quite good.

Thanks for the correction on doubles in commercial software.
