GitHub - dpwe/audfprint: Landmark-based audio fingerprinting
Landmark-based audio fingerprinting. Create a new fingerprint dbase with "new", append new files to an existing database with "add", or identify noisy query excerpts with "match". "precompute" writes a *.fpt file under precompdir with precomputed fingerprint for each input wav file. "merge" combines previously-created databases into an existing database; "newmerge" combines existing databases to c
