Re: [gnuspeech-contact] synthesis speed

[D.R. Hill]

Hi Lee,

On the NeXT, the original software could manage real time with longer tube 
lengths (15 cm or longer).  The NeXT only ran a 6800x at max 33MHxz 
(Turbo) and a DSP 56000 signal processing chip for the actual tube -- 
essential for real-time performance.  The DSP speed was the limiting 
factor.

These days processors go up to 3 or more GHz and include some very 
DSP-like instructions so a DSP is not needed.  Just how fast the system 
will run depends on the processor speed.  On my 1.6GHz Mac running OS/X 
10.3 with the Mac version of the software it was several times faster than 
real time -- depends on optimisation, whether Altivec is used, etc.

I could give actual figures if necessary.

All good wishes.
