https://github.com/AddictedCS/soundfingerprinting Is the library. It was the first thing I found and it seemed to do the job. I’m not a .NET guy so it’s implemented as a CLI tool that takes a wave file as input and spits out a list of timestamps.

Sharing the code would mean getting into the business of publishing an ad blocker which is not something I personally have the bandwidth for. It’s also far from my finest work, being something that I banged out in a weekend. Happy to answer other questions about it, though!
