EasyLRC is a web-based lyric processing tool designed to provide an intuitive and feature-rich LRC creation platform for creating, editing, and synchronizing lyric timestamps. It supports widely adopted LRC standards and is compatible with non-industry standard syntax. It integrates audio playback with synchronized preview functionality and supports parsing and exporting metadata, allowing users to easily create and modify lyric files.
