Thanks I'll check them out, and I was thinking further, I don't really need
the decibels, I think I can do what I need by just getting the volume of
the recording (how recording software has the graph that goes up and down),
or maybe that is the decibel, not sure yet.

I believe https://github.com/mdlayher/waveform does what you're hoping to
do, and uses it to generate waveform images.
Matt Aimonetti, a co-founder of Splice, has several audio-related libraries
at https://github.com/go-audio, and a great non-Go-specific article about
generating waveform data
