Can I convert SRT subtitles to karaoke lyrics?

Yes. If you have SRT subtitles from a musical, concert film, or music video, convert them to LRC to get line-timed lyrics for karaoke software like Karafun, vanBasco, or Kanto Player.

Does the converter support enhanced LRC output?

No. This converter writes line-level [mm:ss.xx] tags only. It does not infer or generate enhanced word-level timing metadata.

How do I create LRC lyrics for songs without subtitles?

If you do not have an SRT file, you need to manually time the lyrics using an LRC editor (LrcEdit, MiniLyrics editor) or a karaoke timing tool. This converter requires an existing SRT file as input.

What music apps display LRC on iPhone?

iOS music apps that support LRC include Foobar2000 for iOS, VLC for iOS, and several third-party lyric display apps. Apple Music does not natively support LRC, but some third-party apps can overlay LRC lyrics on top of any audio playback.

Can I convert multilingual SRT subtitles to separate LRC files?

A standard SRT file contains one timed text track rather than selectable language tracks. If you have separate SRT files per language, convert each one individually and name the outputs by language.

Absolutely. All conversion happens client-side in your browser. No subtitle data is ever transmitted to a server.

What file extension should LRC files use?

LRC files use the .lrc extension. The file must be named identically to the audio file (minus extension) for automatic detection by music players. For example, track.mp3 needs track.lrc in the same folder.

How small are LRC files compared to SRT?

LRC files are typically 40-60% smaller than SRT because they omit end timestamps, cue numbers, structural blank lines, and the arrow separator. A 50 KB SRT file produces roughly a 20-30 KB LRC file.

Can I batch convert multiple SRT files to LRC?

Yes. Drop several SRT files on this page and they open together in the workspace Batch tool with the LRC format pre-selected, converting every file at once. For converting whole folders at scale, use the Batch Converter page.

Does LRC support metadata like song title and artist?

LRC files can include optional ID tags at the top, such as [ti:Song Title] and [ar:Artist Name]. SRT has no metadata section, so this converter does not generate those tags; add them manually if needed.

What about songs longer than 60 minutes?

Standard LRC format uses [mm:ss.xx] without hours, which works for songs up to 99 minutes 59 seconds. For extremely long content (audiobooks, podcasts), the extended LRC format with hour support may be needed.

Can Discord bots read LRC files?

Many Discord music bots support LRC for displaying timed lyrics in chat during playback. Convert SRT subtitle timing to LRC format and upload it alongside the audio for bot integration.

How do karaoke apps use LRC timing?

Karaoke applications read each [mm:ss.xx] timestamp and highlight or scroll the corresponding lyric line at that exact moment during audio playback. The single-timestamp-per-line format makes LRC ideal for real-time lyric highlighting.

Does it support CJK (Chinese, Japanese, Korean) lyrics and multilingual bilingual LRC?

Yes. The tool fully supports UTF-8 Unicode encoding, accurately parsing and preserving structure for Chinese, Japanese, Korean, and multilingual bilingual lyrics alike.

Core Engine Architecture

About SRT to LRC

Turn SRT subtitles into synchronized song lyrics. This tool reads the start timestamp of each SRT entry and writes an LRC line with a [MM:SS.xx] tag, so subtitles ripped from DVDs, Blu-rays, or downloaded from OpenSubtitles can be reused in music players like foobar2000, AIMP, Poweramp, and MiniLyrics.

Specification Sheet

SRT vs LRC Technical Specifications

Standard Compliant

Input Format

SRT

SRT (SubRip, .srt) is the most widely supported subtitle format. Each entry has a sequential index, a HH:MM:SS,mmm --> HH:MM:SS,mmm time range, and one or more lines of text. It is the default format produced by DVD and Blu-ray rippers, Aegisub exports, and most subtitle databases like OpenSubtitles and Subscene.

Output Format

LRC

LRC (.lrc) is a synchronized lyrics format for music players. Each timed cue begins with a [MM:SS.xx] timestamp tag followed by the text; end times are not stored because players advance to the next timestamp automatically.

Format Differences

SRT uses sequential numbered cues with start AND end timestamps (00:01:30,500 --> 00:01:35,000). LRC uses a single start timestamp per line in [mm:ss.xx] format, with no end time.

SRT timestamps include hours (HH:MM:SS). LRC timestamps typically omit hours since most songs are under 60 minutes, using [mm:ss.xx] format.

SRT files average 1-3 KB per minute. LRC files are about 40% smaller since they drop end timestamps, cue numbers, and structural separators.

SRT is designed for video subtitles where cues appear and disappear. LRC is designed for audio lyrics that scroll continuously with playback.

SRT supports multi-line cues. LRC typically uses one lyric line per timestamp; this converter keeps existing cue line breaks and places the timestamp at the start of the cue.

SRT uses comma for millisecond separator (,500). LRC uses a dot or period (.50) for centisecond precision.

Conversion Troubleshooting & Gotchas

Practical solutions for player compatibility, character encoding, and timing synchronization

4 Common Gotchas

GOTCHA #1

Why doesn't the last line of the song lyric disappear when the music ends?

In the standard LRC specification, lines do not possess end timestamps. To make the last line vanish when the vocal ends, AllSubConverter can insert a blank timestamp cue `[mm:ss.xx]` at the end of the file matching the final cue's end time.

GOTCHA #2

Lyrics appear out of sync or ahead/behind the vocal track

Music videos often have intro credits, silence, or countdown bars that audio tracks do not. If your LRC is offset by a fixed number of seconds, you can insert an offset tag `[offset:+/-milliseconds]` at the top of the LRC file, or use our Subtitle Sync tool to shift timestamps before conversion.

GOTCHA #3

Multi-line subtitles look broken or truncated on mobile music players

Most mobile music players (Poweramp, Apple Music, Spotify, Walkman) expect one single line per timestamp. When an SRT cue has multiple lines (e.g. bilingual subtitles), our converter joins them with a space or clean delimiter to prevent lyric overflow.

GOTCHA #4

Songs longer than 60 minutes or audiobooks timestamp handling

LRC timestamps traditionally use `[mm:ss.xx]` where `mm` accumulates past 60 (e.g., 75 minutes is represented as `[75:00.00]`). Our converter properly handles long audio durations without resetting the minute counter to zero.

Why Convert?

Subtitle files from OpenSubtitles, YIFY, and DivXSubtitles are distributed as SRT, but music players such as foobar2000, Poweramp, and Musicolet use LRC for synced lyrics display.

Karaoke software such as Karafun, vanBasco, and Kanto Player use LRC format for timed lyrics, not SRT subtitle files.

LRC uses a single timestamp per line and omits end times and cue numbers, so it is usually smaller than the equivalent SRT file.

Musicians and content creators can repurpose existing movie subtitle timing as a starting point for song lyrics synchronization without re-timing everything.

Language learning apps that display synced lyrics during audio playback expect LRC format, not subtitle SRT files.

Discord music bots and streaming overlays that show timed lyrics alongside audio playback use LRC, not SRT.

Older iPod and MP3 player firmware supports LRC synced lyrics but has no SRT subtitle playback capability.

Scenarios

Common Use Cases

Movie Subtitle to Song Lyrics

Frequently Asked Questions

LRC is a synced lyrics format used by music players. Unlike SRT which has numbered cues with start and end timestamps, LRC has a single start timestamp per line in [mm:ss.xx] format with no end time, no numbering, and no structural separators. LRC is optimized for continuous lyric scrolling in audio apps.

Name the LRC file identically to your audio file (e.g., song.mp3 and song.lrc) and place them in the same folder. Most music players automatically detect and display the LRC lyrics that scroll in sync with the audio playback.

End timestamps are discarded entirely. LRC only uses start times because lyrics scroll continuously rather than appearing and disappearing like video subtitles. The converter uses only the start time from each SRT cue.

LRC is supported by foobar2000 (with ESLyric plugin), Poweramp, Musicolet, AIMP, MusicBee, MediaMonkey, Oto Music, and many mobile music apps. On desktop, foobar2000 and AIMP are the most popular LRC-compatible players. On Android, Poweramp and Musicolet lead.

SRT start timestamps in HH:MM:SS,mmm format (00:01:30,509) are converted to LRC [mm:ss.xx] format ([01:30.50]). Only the start time is used; end times are discarded since LRC does not support them. Sub-centisecond milliseconds are truncated.
