LRC SRT Lyrics Converter

LRC is the de-facto lyrics format of music players: each line starts with a [mm:ss.xx] timestamp in centiseconds and carries no end time, so a converter must synthesise durations — the established convention gives every line the next line’s start as its end, and the final line a fixed duration (3 s by default, configurable), which mirrors how players such as foobar2000, Poweramp and Musicolet hold a line until the next one. This tool implements exactly that, plus the format details that trip up naive converters: ID tags ([ti:] [ar:] [al:] [by:] [length:]…) are separated from lyric lines; the [offset:±ms] tag shifts lyrics globally — positive makes them appear sooner — and is applied (or ignored) on request; a single physical line may carry multiple timestamps ([00:12.00][00:56.10]chorus) and becomes one cue per timestamp, sorted by time; enhanced A2 word-timing tags (<mm:ss.xx>) are stripped from the text (keeping the words); and 2- or 3-digit fractional parts are both accepted. An optional per-cue maximum duration caps cues across long instrumental sections (guitar solos otherwise hold one lyric for the whole gap). In the SRT→LRC direction each cue becomes [mm:ss.xx] plus its text on one line (multi-line cues joined with spaces) using 2-digit centiseconds, the classic player-compatible form. Text is never altered — only timings are translated between the two conventions.
