get decibel level from audio stream or file

[Jeff Mangan]

I want to know if there is a, internal or other package to get the decibel level from an audio stream or file say every second, or few seconds, etc... I tried searching and have not found anything.

Anyone know of a way to accomplish this with golang?  I'd rather not use c#, java, etc...

Thanks

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  https://matt.aimonetti.net/posts/2019-06-generating-waveform-data-audio-representation/.

I hope this helps with your search.

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.
