Hope it will be useful!

This lib is a brick in an adblock for radio broadcasts I have been developing for a while and that I am progressively open sourcing.

How closely can it correlate audio broadcasts of the same audio that were captured at different offsets?

e.g. two independent streams, identifying the same 30-second commercial, but the audio streams are offset from each other by half a sample length?

It correlates quite well.

Maybe some fingerprints will be present in only one of the two streams, but most of them will be present in both.

Have you considered building a podcast player app that can automatically skip ads?

Yes, I more or less have, but isn't the fast-forward option in podcasts players good enough?

BTW a few months ago, I talked to an Australian dev that did podblocker.com, but the project does not seem active anymore

I don't actually mind the ads, but fast-forward is a pain if you're listening when doing other stuff at the same time (running, biking, driving, cooking, etc).

Care to share more details of how it works? Thanks!

This, I will publish at a later time ;)
