Identifying a mp3 file - Githubissues

Gh0s7 commented 11 years ago

I'm sorry for opening this issue but I can't find the solution to my problem.

I'd like to use jEN to identify and tag a mp3 file which has incorrect informations.

I'm trying something like this: Track track = en.uploadTrack(file); track.waitForAnalysis(30000); if (track.getStatus() == Track.AnalysisStatus.COMPLETE) { Song s = new Song(en, track.getID()); System.out.println(s.getArtistName());

but it throws an exception

Gh0s7 - you are attempting to create a Song using a track ID. You need to create a Song with a Song ID. If we were successfully able to resolve your track to a song, then you should be able to call track.getSongID to get the song ID associated with the track.

Is the generation of track fingerprints outside of the scope of this library?
