Can any of your Song Meters record infrasonic sounds?

The Song Meter SM4 has not been tested to record below 20Hz, but anecdotally we have heard customers doing so to record elephants, rhinos, etc. We do not recommend the Song Meter Mini nor the Micro for infrasonic projects. These models employ fixed high-pass filters and will not record useable signals below 20 Hz. With the SM4, the HPF can be turned off.
