Offline FreeDB – Example

It’s been quite a while since I released Offline FreeDB. In the meantime I’ve been too busy to go more into detail. Here at last I’ll show to you how to implement the fast Offline FreeDB Java library to query the FreeDB database and find information for almost any disc or bundle of music files you’re looking for.


What’s required?

OFDB source code or a new Java project with latest OFDB library or declared OFDB Maven dependencies.

   1.0.16
 

About 1 GByte of free disc space for the latest FreeDB file from http://ftp.freedb.org/pub/freedb/. By today it’s freedb-complete-20151001.tar.bz2.

About 6 more GByte of free disc space for the extracted freedb (.tar) and index.

How to query the library?

Just change paths to the latest FreeDB archive name. During the first run it’ll take 15 minutes to extract and index its content.

Provided track durations are given in seconds and very likewise a folder on your filesystem it’s orders are mixed.

Error parsing: Query returned empty response

What’s the result?

All results are sorted by total deviation in seconds. They contain deviance like original track number and all information from FreedDB such as titles and artists.
