Hello Larry,

Swarm does realtime spectrogrmas of log of frequency and log of power
displays of seismic signals.

You could go directly to from winsdr to earthworm to a waveserver and
from the wave server to Swarm.  I know what I just said is cryptic but
if you need more detail I would be glad to get it to you.  I can send
you a screen shot of what the display looks like if you want.
