What happened to perpetual technologies?

I disgree about the cost of room correction systems. Research
seems
to indicate that at least 1 second of room correction (or 1 Hz
correction resolution) is desirable. At 44.1 kHz, and done
with FIR
filters, this amounts to about 44.1k*44.1k = 1.9 billion
multiply and
additions (MACs) per second, and over 8 billion MACs per second
for 96
kHz processing, a sample rate at which many receivers and
surround
prepros are operating at today. That is well beyond
affordable, and
even achievable. Top-of-the-line Pentiums and Athlons can
barely
achieve Dhyrstone MIPS at half these numbers, and those numbers
are
unrealistic and inflated anyway, given that Dhrystone isn't a
realistic, or even meaningful benchmark.
I agree that it's not as cheap as the previous poster was
claiming. However, your argument using general processors is not
valid. In the realm of DSPs and ASICs this level of processing
power is certainly achievable at modest cost.
