Does anyone know if soundcard approach is likely to work? See our mailinglist archive. We discussed this topic for a long time. The problem is optical isolation (vital for safety) and the possible cut-off of low frequencys due to the highpass input filters of the soundcard. Symbol 7F00,0000,0000Arial > 2. Where are the designs that this group has come up with ? > I looked on the web site, but don't see any circuits. The current (modular and improved) version is not yet finished (layoutet). It also hasn't been tried out yet. An older version works perfectly. The new version is safer, has better anti-alias filtering and some advanced features like right-leg drivers.
