I do not know of a system for recording seismic data with a sound card.
You would not be able to attach the seismic signal directly to the sound
card because the frequency of the seismic signals are too low. There might
be a way to modulate a higher frequency with the seismic signal and record
that. However I don't know how one would easily interpret the modulated
I will send your question to the Public Seismic Network mailing list to
see if one of the members can provide some advice.
A good, inexpensive option for seismic recording uses a Dataq.com
analog to digital converter (AD). They have one model that sells for just $25
See: http://dataq.com/194.htm It connects to the serial port of a PC.
This AD will work with the free AmaSeis software provided by Alan Jones.
I've posted a lot of information that would be useful for setting up a
seismic station here:
