A complete step-by-step guide — no special skills needed.
Go to the app →When you open the site, you will land on the «1 Tracks» tab.
Click Choose file and select an audio file from your computer.
Alternatively, drag and drop the file directly onto the grey upload area.
Once the file loads, its name will appear and the next step will become available.
Click Separate tracks.
The site will automatically split the song into two tracks:
When separation is complete, you will see two waveform tracks and a playback button. Press ▶ to preview the result.
Volume controls (left panel):
Vocal editing only affects how the site synchronizes lyrics - it does not change the final exported video.
Use this step if the song contains unwanted audio that might confuse the synchronizer: background noise at the start or end, spoken words before or after the singing, or stray vocal runs and ad-libs in the middle. Muting those sections helps the site pinpoint where each lyric line actually starts and ends.
How to open the vocal editor:
Three editing tools:
Typical workflow:
When finished, click Vocal editing again to close the editor, then continue to Step 4.
Click the 2 Text tab at the top of the screen.
Paste or type the lyrics into the large text field.
✅ Correct:
❌ Incorrect:
Below the text field you will find a language selector. We recommend leaving it on «Auto-detect» - the site identifies the language correctly in most cases.
Click Synchronize text.
The site analyzes the vocal track and determines exactly when each word is sung, then assigns timing to every line automatically.
When «Done» appears on the button, synchronization is complete.
Press ▶ - or tap Space on your keyboard - to preview how the lyrics scroll along with the music.
If some words or lines are slightly out of sync after automatic synchronization, the 3 Editing tab lets you adjust them by hand.
Two editing modes:
Moving and resizing clips:
Selecting multiple blocks and moving them together:
Countdown block before singing starts (1·2·3·4 or 1·2·3):
If you want to give the vocalist time to get ready before the first line — add a countdown block. In the top panel of the Editing tab, drag the 1·2·3·4 button onto the lyrics track at the desired position. Use the arrows next to the button to choose the mode: ▲ = 4 beats, ▼ = 3 beats.
In the preview window and in the final video, the countdown number appears on the left inside a circle filled with the lyrics fill color.
Controls at the bottom of the screen:
This step is entirely optional - if you are happy with the default look, jump straight to Step 8.
Options available on the «2 Text» tab:

These shortcuts let you work faster without reaching for the mouse.
Play / Pause
Start or pause playback. Works on any tab, as long as the cursor is not inside a text input field.
Cancel active operation
Cancels stem separation if it is currently running. Also cancels video rendering during export.
Move a selected clip frame by frame
Click a video or photo clip to select it, then use the arrow keys to nudge it precisely - each press moves it by 1 frame (≈ 33 ms). Hold Shift to move by 1 second per press.
Delete selected clip
Removes the selected video or photo clip from the timeline, as well as a selected 1·2·3·4 countdown block. You must click the clip first to select it.
Select multiple lyrics blocks
Hold Shift or Ctrl and click lyrics blocks on the timeline — each clicked block is added to the selection. Then drag any selected block to move them all together. You can also select an area by dragging over an empty part of the track.
The lyrics are out of sync - what should I do?
Make sure the text in the lyrics field matches exactly what the singer sings. Extra words, missing lines, section headers (like [Chorus] or [Verse]), or line number prefixes will throw off synchronization. Clean up the text and click «Synchronize text» again.
Stem separation is taking a long time or failed with an error?
Refresh the page and try again. Make sure the audio file is not corrupted and is in a supported format (MP3, WAV, or FLAC).
Can I create an instrumental-only (backing track) version?
Yes. On the Export tab, uncheck «Include vocals» and leave «Include instrumental» checked. The exported video will contain only the music without the voice.
The site says my screen resolution is not supported?
The site requires a screen resolution of 1920 × 1080 or higher. It is not designed for phones or tablets - please use a desktop or laptop computer.
How do I start a new project?
Click the New project button at the top of the page. This will clear all current project data so you can start fresh.
What happens to my files - is my data safe?
Only two tasks are sent to our server:
Everything else - timing adjustments, appearance settings, vocal editing, video rendering, and export - runs entirely in your browser, using your computer's own resources. Nothing else is sent to our servers.
Rendering and export speed depends on your computer's hardware. A modern CPU and GPU will produce the finished video significantly faster.
Follow these 8 steps and you'll have a finished HD karaoke video.
The whole process typically takes 5-10 minutes.
