FAQ

KAR to CAL Conversion

What are KAR files?

KAR is a karaoke music file. Like an ordinary MIDI file it stores the melody and the accompaniment as notes, and in addition it holds the words of the song, split into syllables and timed to the music. A music program can show it as sheet music with the lyrics written under the notes, and a karaoke player highlights the words as they are to be sung. The format was created in 1993 for the Soft Karaoke product and is still widely used for karaoke songs.

What are CAL files?

A CAL image file represents a monochrome bitmap image that uses the CALS raster image standard for storing graphics data. This standard was created in the 1980s by the US Department of Defence as a compressed interchangeable image format. CAL and CALS are extensions used for similar purposes.
