Re: Infrasound recorder

["Randy Perretta" first_avatar]

I'd be real careful. Very few recorders go that low. Most bottom out at 20Hz. 
They usually have DC blockingcaps on the inputs. Bass response is quite 
commonly associated in quality with something that came from the wrong end of 
the elephant. 

I just Googled for digital recorder frequency response. After a few pages, I 
gave up. 20Hz is it. 

Maybe someone knows of something portable that goes to DC.  Personally, and 
this is just me, Id be looking at scientific Or seismic gear (there's plenty of 
infrasonic seismic gear out there suitable for field work) rather than audio or 
contact the research staff at a place that does whale research and see what 
they use.

Good luck,

Randy
