Making Karaoke Files at Home: A Complete Walkthrough

What a karaoke file actually is

Most home karaoke doesn't use a special file format at all, it uses the same LRC synced-lyrics file that music players read. A karaoke app plays the audio and highlights the current line from the LRC as it's sung. So "making a karaoke file" really means "making a synced LRC file", which is exactly what Lyricron does. (Some setups use .cdg or .kar, but LRC is the open, universal option.)

Step 1: get the song and the lyrics

Grab an audio file of the track, and the lyrics as plain text. Instrumental or "backing-track" versions work just as well as the full song, the timing is identical. If you only have a vocal version, karaoke apps will simply play it as-is while highlighting the words.

Step 2: time the lyrics

Load the track and lyrics into Lyricron, press play, and tap the moment each line starts. Leave a blank line where the instrumental breaks are so the highlighting pauses during the solo. The full tap-along flow is in how to sync lyrics to a song.

Step 3: export

Download the .lrc file and drop it next to the audio file with a matching name. Most karaoke apps find the lyrics automatically when the filenames match. For the popular players, there are dedicated guides for VLC, Musicolet, foobar2000, and Poweramp.

Tips for a clean result

• Time the first sung syllable of each line, not the breath before it.
• Stamp blank lines for intros, outros, and instrumental breaks.
• If a line is off, nudge it 50 ms at a time rather than redoing the pass.
• Use the keyboard so your taps land closer to the true beat, covered in the keyboard-first workflow.
