Hello, Mr. Hwang,

Okay, problem is solved.  One of my cats (who now just might lose one of his nine lives) pulled against the cable going into the monitor.  The cable was loose and it interfered with the signal.  It happened yesterday while I was in your Forum.  Anyway, it's fixed.  Thanks for your time and consideration.

Need a cat in Taiwan?

No. Thank you. I do not need a cat to pull my cables.  ;)

Thank you very much for your help and time. :D

Voice recognition is the wave of the future in that even with online education, one will be able to eventually use voice commands -*- This GED online hypothesis is just one example of what lies ahead in the education sector with voice command. Thank you for your detailed explanation.

Dear Mr. Hwang,

  I was searching for Fourier Transformation for Voice Morphing , and came to your website forum. I checked your Fourier Synthesis program and find it useful. Can you please help me out in applying Fourier Transformation for Voice Morphing?  Looking forward to your kind reply.

I am wondering if anybody can give me a little bit of help with the duality
(or symmetry) property of the Fourier transform.  my book states that it is:

X(t) <-> 2(pi)x(-w)

...And this is pretty much all the text has to say about it.

first is the usage of X(t) as appose to x(t) in the situation to denote the
fact that we are using duality?  My book never mentions why it is suddenly
used, and this seems to be the only time it is used.

Also, when can I use this property, when is it applicable or even useful?
They don't even say where it was derived from, making it that much harder to
figure out.

thanks for any light you might be able to shed.
