These two functions would let me store compressed fingerprints in the database and the decompress for comparison. These are very effective when compressing a fingerprint, especially if you can store the raw (non-base64) version, something like a 4:1 compression ratio.

I would also be interested in the comparison functions, but I read that the chromaprint comparison API is not fully implemented and not exposed in the C headers. I didn't have good luck when trying to use it either.

I do have a simple comparison algorithm that I've seen in a few other projects that I could contribute. It's written in C and based on algorithms that I've seen in other projects (https://codeberg.org/derat/soundalike for one) so maybe it's better off as a secondary module so this one does not require a C compiler 🤷
