MP3+G is a karaoke file format that was created to allow CD+G karaoke to be played from a personal computer easily and quickly. MP3+G was created from the combination of the MP3 audio file (the CD audio is converted and compressed to MP3) and a raw CDG file which contains the RW subchannels from the CD+G track. It was first called MM+G in combination of various audio formats synchronized to a CDG file. MP3 and WMA became the most popular audio format used for karaoke and therefore MP3+G and WMA+G became the most popular formats used. Microsoft first unofficially adopted the WMA+G for use on the Xbox for the Xbox karaoke product.

[edit] The MP3+G format
MP3+G stands for MP3 plus Graphics. MP3+G is derived from the CD+G format and the CD+G disc format invented by Philips. MP3+G is created by extracting the CD-Audio packets from the CD+G disc with a CD-ROM that is capable of also extracting the RW channels from the disc. The digital audio portion is compressed to MP3 and the RW Channels (CD+G graphics) are stored to a CDG file. The player products read each file and synchronize the information to display the interpreted graphics along with the music.
[edit] History of MP3+G
Steve Gray in Jan 1998 wrote WinCDG which was the first MP3+G player [1] and also SJGPlay.
Other products have found a new way to transport the MP3+G pair of files by "zipping" them. A zip file is a data compression format used to compress and contain files together. Containing the MP3+G file pair in the ZIP became known as an "MP3+G Zipped".
Since the creation of the format the technology of MP3+G was first licensed as the Breeze engine by Tricerasoft. It was later released as a codec engine technology to various computer software companies, including;
- TouchPoint
- PCDJ
- DJPower
- Alcatech
- Hercules
- AVA Systems
