kn5l's question suggests another: How do you measure reliably audio rms
power? (Say for EME Sun noise.)

It turns out, the Windows program Daqarta work perfectly with either sound
card audio or USB audio. Go to "Options," then "measure..." , then "dB."  I
believe the 30-day free trial, when expired, leaves these functions behind.

The dB baseline button is very useful.
