MP3, M4A, WAV, FLAC, and other audio, or a video with sound.

How to make an LRC file

Open the song and paste its lyrics, or select Find lyrics to look them up in LRCLIB. Select Tap along and press Space as each line starts, then drag any line on the timeline to fix its timing, and download the .lrc file. Music players such as Poweramp show an LRC file's lyrics in time with the song. You can make a lyric video from the same timing too.

  1. Step 1

    Choose a song
    Then find or paste its lyrics.

  2. Step 2

    Tap along
    Tap as each line starts while the song plays.

  3. Step 3

    Download the LRC
    Save the timed lyrics as an .lrc file.

What to expect

Supported inputs
MP3, M4A, FLAC, WAV, and other songs this browser can read, with lyrics pasted, found, or opened from an LRC or text file.
What happens
Each tap marks when a line starts, to a hundredth of a second. A line that ends before the next starts gets an empty line where it ends, as LRC marks a pause. The LRC file has the song's title, artist, and length, then one timed line each.
Limits
Finding lyrics sends the song's title and artist to LRCLIB; the song stays on your device. Taps tend to come a little late, so every line can be moved earlier or later at once from the lyrics menu. Lines are timed, not single words.

Questions

A plain text file of lyrics with a time before each line, like [01:02.50]. Music players read it to show each line as it's sung. It's named like the song, ending in .lrc.

Yes. Drag it on the timeline, or click it and use Earlier and Later, which move it a tenth of a second at a time. You can also select Tap along with the line picked and tap it again.

Yes, with no sign-up and no limit on length. It runs in your browser, so the song is never uploaded.
