What is a .cdg file?
File extension details and usage information
The CDG file extension stands for Compact Disc plus Graphics and is a legacy format primarily used for karaoke. This format is an extension of the standard Red Book audio CD (CD-DA) specification. It utilizes the 'subcode' channels R through W, which are typically unused in standard audio playback, to store low-resolution graphical data. These graphics are synchronized with the audio track to display song lyrics that change color or highlight in time with the music, providing a visual guide for the singer. Because the data rate of these subcode channels is extremely low, the graphics are limited to a resolution of 300x216 pixels and a palette of only 16 colors, resulting in a blocky, 8-bit aesthetic. In the modern digital era, CDG files are rarely used on physical discs and are instead paired with MP3 files to create 'MP3+G' sets. In this setup, the MP3 file provides the high-quality audio while the CDG file contains the synchronized lyric instructions. To play these files correctly, software must be capable of reading the CDG data and overlaying it as a video stream while simultaneously playing the associated audio file.
