Greetings.

As one of the people involved in the development of Khoros 1.0's signal
processing library, I would like to thank you for this excellent feedback.

We are in the process of designing the data services and its API for various
domains for Khoros 2.0.  The data services API for signal processing will be
much more well defined in K2.  Additionally, the new viff file format 
supports signals in a much more intuitive fashion. 

The interactive signal editor, along with an interactive filter design
application and other such programs have been discussed internally 
on numerous occations.  I agree that applications such as these 
would represent a great improvement in the functionality of this aspect
of khoros.  It would be nice if we could get support for the development
of such an application.  I would very much like to see a few customized
applications for signal processing such as these added to the khoros
system.  

I am going to store your message in the K2 development account for
future reference.

Thanks again...

| A while back, I posted something asking who was using khoros for 
| signal processing, and how the environment could be extended for
| this use.  This is a summary of the replies I got.
| 
| 1.  There are lots of people out there who _WANT_ to use
| khoros for signal processing.  I had replies from engineers and
| biological scientists who want to represent audio signals, and other
| signals, and to be able to work with them in the khoros environment.
| Most of these people feel that khoros _COULD_ be great for signal
| processing.  Lack of an interactive signal editor, with graphical
| marking of samples and high-level signal manipulation was generally
| lamented.  (I strongly agree with this.  An equivalent of editimage
| for 1D signals would place khoros in a league of its own compared
| to other available packages, and shouldn't be hard to write.)
| 
| 2.  The availability of an extensive library of signal processing
| routines within khoros is a great advantage, and much appreciated.
| 
| 3.  A number of people (myself included) would like to more about
| the viff file format, and how it handles 1D signals.  A cookbook
| chapter on header information for 1D signals, and how to write
| viff files for single or multichannel signals would be useful
| 
| 4.  CONCLUSION.  The interest in signal processing with khoros
| seems to be there, as is the potential.  Many users hope that
| the khoros group may be able to find the time and resources to
| bring these various components together to create a complete
| signal processing environment, with enhanced interactive 
| manipulation and graphical facilities to take us beyond
| xprism.
| 
| P.S.  A lot of us guys don't have the money for colour monitors,
| and we don't really need them for 1D signals only.  So if any
| development of new software does take place, please don't restrict
| it to colour hardware!
| 
| Cheers
