Are 98 Mb for sounds stored in 48 Mb via compression in Tyros?

Clif Anderson, speaking about PA80, refers 32 Mb for sounds in PA, and said:
QUOTE: "32 Mb still leaves them far behind the Tyros' 96MB (well, maybe not, since the Tyros' 96MB is probably stored in 48MB via compression.)"
It is something new to me. I was thinking when Yamaha or other say 96 Mb for sounds, is exactly 96 Mb, not 96 Mb compressed in 48 Mb.
So, there is something not clear about Mb for sounds, if not all manufacturers count Mb at same way (for ex. some real Mb, some compressed Mb).
Are 98 Mb for sounds stored in 48 Mb via compression in Tyros, as Clif ask? And what about other (Technics, Roland...)? Any opinion about that?
Cheers

Hi As George say, probably all manufacturers compress its Mb for souds. No problem about it.
My question was more in other direction. We usually khink that "more Mb for sounds = more quality of sounds"
So, a kb with 16 Mb would have better sounds than comparable kn with only 8 Mb (being numer of sounds similar).
But, if manufacturers compress its Mb for sounds at different rates of compression (and not declare them), comparations become more difficult.
Probably, the best way would be manufacturers make explicit both "theorical" Mb for sounds and "actual" Mb for sounds after compression.
A recent example may be PSR2100. I played it a little, and compared with PSR2000. Yes, new 2100 has a few new sounds, but all the rest ones are similar and sound similar to PSR2000. Yamaha say psr2100 has double Mb for sounds than PSR2000. Well, I suppose it is true, but honestly, my ears don't listen so much difference at all. Perhaps differents compression rates...
But the problem is more evident comparing different manufacturers, because probably each one compress Mb in a more similar way than if we made comparison with other manufacturers.
So, question would be to know if compression uses and rates are different in different manufacturers. If "yes", 32 Roland Mb would be comparable to 32 Yamaha Mb. If not, it is a nightmare.
Thinking about it, I remember someone said here that ways to counting polyphony aren't similar between different manufacturers (because layer sounds, etc). Perhaps, it is something similar.
Cheers
