View source for MP3 ID3v1 and ID3v2 extractor

Selecting '''File > Extract > Media > Extract ID3V[12] from MP3s''' starts Wandora's MP3 extractor. As the name states Wandora is capable to transform [http://www.id3.org/id3v1.html ID3v1] and [http://www.id3.org/ ID3v2] metadata to topics and associations. Wandora uses [https://jid3lib.dev.java.net/ jid3lib] to read metadata out of MP3 files.

When you start the extractor, Wandora first asks you whether it should process local or Internet files. If you decide to process local files, Wandora asks you next where to start looking for the files. You can point the actual MP3 files or a folder containing the files. If you decided to crawl Internet files, Wandora asks you the URL where to start. Starting URL can be either an MP3 file or HTML page containing links to MP3 files. Wandora also follows links in HTML page if they are in the same domain and extracts metadata from all encountered MP3s. Extracting metadata from Internet located files can be very slow task because Wandora must download each MP3 file before metadata extraction.
