chromaprint VS Tenacity

you could always cut up the video into segments A,B,C,D,E using like ffmpeg -ss 00:00:00 -t 00:10:00 -i input -c copy A.ext (where A is the first 10 minutes of video) and then recombine with https://trac.ffmpeg.org/wiki/Concatenate, might take a while though and some basic math. maybe you could do something programatically with chromaprint by identifying the repeating audio segments? that's just an idea since that's what this jellyfin plugin does to identify repeated segments of shows in the form of opening credits.

I'm currently doing the same. I'm using the chromaprint library via the pyacoustid library, using the technique described here, which should give a certain amount of leeway in terms of pitch and other variables. See also the notes in the chromaprint documentation about truncating the samples to reduce noise.

There is a music fingerprinting project called Chromaprint. The fingerprints generated by this library are widely used in music database, including Musicbrainz.

Else Tenacity is an active fork of it which doesn't seem to accept donations hmm: https://github.com/tenacityteam/tenacity

Not anymore, unfortunately. They were bought out by an extremely shady company. Please look into forks of the project i. e. "tenacity" https://github.com/tenacityteam/tenacity. The details on the controversy around audacity also can be found on the page.

Tenacity also seems dead. This had the most active marketing, even set up donations and received $575 (so far); I wonder what will happen to that.

Add both the normal and vocal off versions to Tenacity File > Import audio.

The icon to its left is tenacity, an audacity fork.

I think people underestimate the open source community. When there was some controversy surrounding audacity, a successful fork was created (tenacity). Same goes for youtube-dl, which stopped regularly updating and has since been "replaced" by yt-dlp.
