CueGenerator 1.0.0

The problem

I have a mixed MP3 liveset of a DJ and I need to burn it on a CD. Yes, the question will pop up: "OMG! CD?! Do they still exist?". Sure, everybody is using iPod, MP3 player, etc, etc, ... now, but I really need to burn it to disc.

I have a tracklist which tells me how long the individual tracks last. So based on this information, I could build a CUE file. This CUE file can be delivered to "whatever" burning software. It will burn the MP3 file to disc, but it will make indexes when a new individual track starts. More information about CUE files: http://en.wikipedia.org/wiki/Cue_sheet_(computing)"

Seems great, and I'm lucky, because there are a lot of CUE generators on the web:

• http://www.cuegenerator.com/
• http://cuegenerator.net/
• ...

But, the problem with each of these generators, is the timing input. You have to manually add the time of track 1 on track 2, track 2 on track 3, etc, etc, ...

Example:
Track 01 takes 06:42
Track 02 takes 04:12

I just want to provide the above numbers into the generator, but according to the CUE definition, I have to input:


TRACK 01 AUDIO
TITLE "Reverence"
PERFORMER "Faithless"
INDEX 01 00:00:00
TRACK 02 AUDIO
TITLE "She's My Baby"
PERFORMER "Faithless"
INDEX 01 06:42:00
TRACK 03 AUDIO
TITLE "Take the Long Way Home"
PERFORMER "Faithless"
INDEX 01 10:54:00


Of course, you can do this quickly yourself or by Excel, but I'm a software engineer, so I developed my own application ;-)!

The solution

• Create a CSV file, having the following format:
  
##GENRE##
##DATE##
##PERFORMER##
##TITLE##
##FILE##
##TRACK_01_ARTIST##;##TRACK01_TITLE##;##TRACK_01_MINUTES##;##TRACK_01_SECONDS##
##TRACK_02_ARTIST##;##TRACK02_TITLE##;##TRACK_02_MINUTES##;##TRACK_02_SECONDS##
...

• Download the following pom.xml and source file src/main/java/be/jochusonline/cuegenerator:

• Run mvn eclipse:eclipse on a command prompt. You need Maven to perform this operation. You can download it from: http://maven.apache.org/. This operation will generate a .project file. Import that project into Eclipse.
• Once imported in Eclipse, use the built-in run dialog. Eclipse will output the file to the console
• At the bottom of the file, there's an extra check to be sure you didn't provide any incorrect data
