Drop in an MP3, WAV, FLAC, M4A or OGG and paste the lyrics you already have. No lyrics on hand? Switch to AI transcription and upload the audio on its own.
The vocals are separated from the music, then each word — from your text or from the AI transcript — is aligned to its own timestamp. No tapping along.
Check the timed lyrics against the waveform, fix any word or timing in the LRC editor, then export LRC, enhanced LRC, SRT, VTT or plain text.
Every sync here is timed down to the word, so the same result exports as a line-by-line .lrc or as an enhanced LRC with a timestamp on each word.
One timestamp per line. The player scrolls and highlights a line at a time. Nearly every player that shows synced lyrics reads this format — start here if you're not sure.

Best for Phone players, portable players and media servers
Adds a <mm:ss.xx> tag in front of every word, so a player can light up each word as it's sung. In the export menu it's called Word-by-word LRC.

Best for Karaoke apps and players with word-by-word lyrics
Word-by-word display depends on the player. Apps that don't read the word tags fall back to line timing or show the tags as text — if that happens, export standard LRC instead. Chinese and Japanese lyrics are timed per character.
From a personal music library to a release-day lyric video, timed lyrics are the raw material.
Export enhanced LRC with a timestamp on every word — the word-by-word format karaoke apps and players light up in sync.
Before a release, paste your final lyrics against the final mix, get line and word timing, and take it straight into a lyric video.
Give the songs in your own library the synced lyrics that lyric databases don't have. Drop the .lrc next to the track for Poweramp, Musicolet, Samsung Music, a Walkman, Plex or Jellyfin.
Turn a song or a vocal track into SRT or VTT subtitles that follow the singing, ready for YouTube, TikTok and Reels.
An LRC file is a plain-text lyrics format where each line starts with a timestamp like [01:23.45], so music players can scroll and highlight lyrics in sync with the song. The enhanced (word-by-word) variant adds mm:ss.xx tags inside each line for karaoke-style highlighting.
Upload your song and paste the lyrics. The generator keeps your text and assigns a timestamp to every line and word — no manual tapping. If you don't have the lyrics, switch to AI transcription and it writes them down first. Review the result in the editor, fix anything you like, and download the .lrc file.
Yes — it's the most common way people use it. Paste your lyrics before generating. The generator keeps your exact text and line breaks and only computes the timestamps, which is both faster and more accurate than transcribing from scratch. It's effectively a TXT to LRC converter.
Yes. Switch to Transcribe with AI and upload the MP3 (or WAV, FLAC, M4A, OGG — up to 10 MB and 10 minutes). The AI transcribes the vocals and times every word, and you get an editable result to export as a .lrc file.
Each song costs 50 credits to sync. The Free plan includes 120 credits a month, shared across Lacuna — enough for 2 songs if you spend them here. On the Free plan you can play the result, edit words and timing, and translate lines. Downloading or copying the finished file — LRC, enhanced LRC, SRT, VTT or plain text — is part of the paid plans, so you can check the result before deciding.
Save the .lrc file with the same name as the audio file, in the same folder — the download is already named after your upload. Players and media servers such as Poweramp, Musicolet, Samsung Music, Sony Walkman players, Plex, Jellyfin and Rockbox then pick it up automatically and display the timed lyrics while the song plays. foobar2000 needs a lyrics component, and VLC does not load .lrc files.
Standard LRC has one timestamp per line — players highlight line by line. Enhanced LRC, also called word-by-word LRC, adds a timestamp to every word, enabling karaoke-style word highlighting. This generator produces word-level timing, so you can export either format from the same sync.
Upload the song, paste the lyrics or let AI transcribe them, and generate. Then open the export menu and choose Word-by-word LRC — that is the enhanced LRC format, with a mm:ss.xx tag before each word. A line without word timing falls back to a single line timestamp.
It depends on the player. Karaoke software and lyric plugins that read word-time tags show word-by-word highlighting. Many everyday music players only use the line timestamps, and some display the word tags as plain text. Test one file first; if your player doesn't handle it, export standard LRC, which works wherever synced lyrics do.
Yes. Lyrics timed for the original release drift on slowed, sped-up, remix and live versions. Upload the version you actually listen to, paste the lyrics as plain text without the old timestamps, and the generator times them against that audio.
Yes. The export menu includes SRT and WebVTT subtitle formats built from the same timed lyrics, ready for YouTube captions or any video editor — plus plain text if you just want the transcription.
English, Chinese, Japanese, Korean, Spanish, Portuguese, French, German, Italian and Russian. The language is detected automatically from the lyrics, and you can override it before generating.
Sync your lyrics in about a minute — then take them straight into a lyric video.
