About the project

Open Anime Timestamps is an open source tool for building a database of opening and ending theme timestamps for anime episodes

It works using acoustic fingerprinting and aggregating data from other databases. A database of fingerprints made from the opening and ending themes is used on individual episodes to determine where in each video file the opening/ending fingerprint appears. The data for the opening and endings, and episodes, is scraped from various sources. Some data comes from existing databases, which is then built off to try and create a "complete" database
