LRC Format Guide - Complete Documentation
Comprehensive guide to the LRC (Lyric) format - the standard for synchronized lyrics in music players, karaoke applications, and multimedia software.
What is LRC Format?
LRC (Lyric) is a text-based file format used to store synchronized lyrics for music tracks. Originally developed for displaying time-stamped lyrics in music players, LRC files contain both the lyric text and precise timing information that allows lyrics to be displayed in perfect synchronization with audio playback.
The format is widely supported across music players, karaoke software, and multimedia applications, making it the de facto standard for synchronized lyrics worldwide.
LRC Format Specification
Basic Structure
An LRC file consists of metadata tags and time-stamped lyrics lines. Each line follows a specific format:
Timestamp Format
LRC timestamps use the format [mm:ss.xx] where:
- mm = minutes (unlimited digits, but typically 2)
- ss = seconds (00-59, exactly 2 digits)
- xx = centiseconds or hundredths of a second (00-99, exactly 2 digits)
Examples of valid timestamps:
- [00:00.00] - Start of song
- [01:23.45] - 1 minute, 23.45 seconds
- [123:59.99] - 123 minutes, 59.99 seconds
