Hey Product Hunt! 👋 I'm Nick, the maker of Lyricron, a free, open-source lyrics timer and LRC editor that helps you create perfectly timed lyrics without the usual headache. Every line, right on time.

First, thank you for stopping by, every upvote, comment, and share genuinely helps a solo maker like me. If you've ever tried to sync lyrics by hand, you already know why I built this. If you haven't, let me show you how much easier it can be.

🎵 The problem: syncing lyrics is a pain

If you've ever made karaoke tracks, subtitle files, or synced lyrics for a music player, you know the ritual. You open a .lrc file in a plain text editor, stare at [00:12.34], hit play, pause, rewind two seconds, guess the timestamp, type it, play again… and repeat that forty-plus times for a single song. Then the second verse drifts, and you start the whole tedious loop over.

The alternatives aren't much better:

- Desktop lyrics editors often feel stuck in 2009, clunky UIs, confusing shortcuts, no dark mode.

- Paid tools lock basic export behind a subscription, which is absurd for a file format that's been open since the late '90s.

- Cloud tools ask you to upload your audio to a server. Your unreleased track, your private voice memos, your client's podcast, all sitting on someone else's disk.

- Manual editing in Notepad or VS Code technically works, but it's slow, error-prone, and genuinely unfun.

I wanted something that felt as fast as tapping your foot to the beat. So I built it.

⚡ What Lyricron is

Lyricron is a browser-based lyrics timer and LRC editor. Play a track, tap Annotate as you listen, and export a ready-to-use .lrc file. That's the whole loop. No timeline scrubbing, no math, no guessing milliseconds by eye.

It's built for speed: most people can sync a full song in a few minutes, then spend the rest of their time fine-tuning instead of fighting the tool.

🛠️ Features, in detail

Load any media

- Drag and drop an audio or video file anywhere on the page, or use the file picker.

- Only the audio plays, so you can sync against an .mp4, .mov, or music video without the distraction of the picture.

- Works with MP3, WAV, OGG, FLAC, M4A, MP4, and anything else your browser can decode.

Add your lyrics

- Type or paste them by hand.

- Import a .txt or existing .lrc file to pick up where you left off.

- Fetch synced lyrics from LRCLIB, a huge open database of time-stamped lyrics, and use them as a starting point.

- Smart paste detection: drop timed LRC text into the plain-text field and Lyricron notices, then asks whether to load it as timed lyrics or convert it to plain text.

Annotate in real time

- Press Annotate (or use a keyboard shortcut) as the song plays to stamp each line at the exact moment.

- Blank lines let you mark instrumental gaps, intros, and outros so your timing stays honest through breaks.

- Big, readable controls, no hunting for tiny buttons mid-song.

Fine-tune with precision

- Inline timestamp editing: click any line and fix it directly.

- Nudge any line by ±50 ms for those "almost perfect" moments.

- Shift-all to slide the whole file earlier or later in one move.

- Full undo / redo, experiment freely, because nothing is destructive.

Keyboard-driven workflow

- Annotate, play/pause, seek, and jump between timed lines without ever touching the mouse.

- Configurable shortcuts, so it fits how you work.

- Once you learn a couple of keys, syncing becomes almost musical.

Playback controls

- Adjustable playback speed for dense or fast lyrics.

- Accurate seeking so you can loop the tricky chorus.

- Dark, light, and system themes, because some of us sync at 2 a.m.

Output and export

- Preview mode to watch your lyrics scroll in time before you commit.

- Optional per-line timestamps for pro-level precision.

- Copy or export to .lrc in one click, compatible with most music players, karaoke apps, and video tools.

Project auto-save

- Your work is saved automatically as you go, so a refresh or accidental tab close won't wipe your progress.

👥 Who it's for

Lyricron is for anyone who needs synced lyrics or timed subtitles:

💡 Why timed lyrics matter

Synced lyrics power karaoke players and lyric videos. Accurate timing is the difference between frustrating and flawless.

Timed lyrics also make music more accessible. They help listeners who are deaf or hard of hearing follow along, support language learners reading as they listen, and keep fans singing every word at karaoke night. Good timestamps turn a plain audio file into something people can read, follow, sing, and share, and they work in players, apps, and devices that already support the LRC lyric format.

🔍 One tool for every search term

Searching for a lyrics synchronizer, LRC timestamp editor, karaoke lyric maker, subtitle timing tool, lyric video creator, or online lyric timer? They're all the same job: matching the right words to the right moment. Lyricron does exactly that, right in your browser, free and private, with no software to install and no files to upload.

🔒 Privacy first, by design

This is the part I'm proudest of, and it's not marketing fluff:

- No account. No signup. No email.

- No uploads. Your audio and lyrics never leave your device.

- Works fully offline once the page is loaded, even the fonts are bundled locally.

Because everything runs client-side in your browser, Lyricron is safe for unreleased music, private recordings, confidential podcasts, and client work. Your files stay yours. Full stop
