Uploading a file is the most straightforward way to create a karaoke track. Youka accepts a wide range of audio and video formats, separates the vocals, syncs the lyrics, and has your project ready in minutes.

​
Supported file formats

Use a high-quality audio file with clear, prominent vocals. Better source quality produces cleaner vocal separation and more accurate lyric synchronization.

Steps to create from a file

1

Open the Create Karaoke page

Click Create Karaoke from the Youka home page.
2

Upload your file

Drag and drop your audio or video file onto the upload area, or click the area to open a file browser and select your file.
3

Enter a title

Give your karaoke a title. Youka pre-fills this from the filename — edit it if you’d like something more descriptive.
4

Add lyrics

Choose how to provide lyrics:
  • I have lyrics — paste or type the song’s lyrics directly. This gives the AI a precise reference and typically produces more accurate timing. See Add Lyrics.
  • Detect from audio — let AI transcribe the lyrics automatically. Best when you don’t have lyrics on hand and the vocals are clear. See AI Transcription.
5

Select the lyrics language

Choose the language of the song. This helps the AI understand pronunciation patterns and handle special characters correctly.
6

Click Create Karaoke

Click Create Karaoke to start processing. You’ll be taken to your project page where you can watch progress in real time.

​
What happens after you click Create Karaoke

Processing runs in four stages:
  1. Upload — your file is transferred to Youka’s servers
  2. Vocal separation — the AI isolates the instrumental track from the vocals
  3. Lyric sync — each word is matched to the exact moment it’s sung
  4. Project generation — your karaoke project is finalized and opened
This typically takes 2–3 minutes for an average-length song.

​
Tips for best results

  • Use the highest quality source you have. Lossless formats (FLAC, WAV) or high-bitrate MP3s give the vocal separation model more detail to work with.
  • Prefer recordings with clear lead vocals. Songs where the lead vocal is prominent and not heavily distorted produce better transcription and sync.
  • Provide lyrics when you have them. Accurate lyrics give the AI a precise reference, which improves word-level timing compared to transcription alone.
