Hi !
About the soundcard idea: could somebody maybe find out how they are accessed
in Windows and Linux ? I think it wouldnīt matter at all if we could use
only high sampling rates like 40kHz. It would be possible to do some filtering
and convert this signal into a slower datastream accessible by our software.
The driver-issue shouldnīt be such a problem.
That leaves us with two problems:
- the bandwith (itīs limited on the lower side so we canīt sample signals below
maybe 5 Hz)
- linear isolation. Distortion and so on could limit the number of usable bits.
Maybe it could be calibrated using a signal generator or something like that.
