[Gloucs] DSP on Linux.

[Geoff Bagley]

I have an interest in processing a weak  narrow band  modulated audio 
signal on about  2.25 kHz (tuneable upwards).
The over-all modulation bandwidth may be no more than 10 Hz,  but this 
is not yet proven.

I would prefer to process the signal digitally.  I have a couple of 
Motorola DSP56002   kits,  but
feel that the ubiquitous  PC sound card might be preferable  since the 
only support software appears
to be based on Micro$oft.

Selection and filtering of the signal may be followed by down-sampling 
and analysis at baseband.

Please does/do  any of you have experience in this field ?  My system is 
Debian Lenny.
I would be pleased to chat with anyone intrigued by this project

Happy New Year.
