Getting started

1. Sign in with your Google account.
2. Choose an audio file from your computer: MP3, WAV, FLAC, M4A, AAC, OGG, OPUS, MP4 or WEBM, up to 80 MB. The track name fills in automatically, and you can change it.
   Is the song in an online video? See how to get an MP3.
3. Click Split into stems. The file uploads, then the track shows Waiting in queue → Separating → Ready.
4. A typical song takes about 5–6 minutes. You can close the page while it works; your track will be in your library when you come back.

Listening and downloading

• ▶ Play together plays the vocals and instrumental in perfect sync, like the original song. Each part has its own volume slider and an ON/OFF button:
  • Vocals OFF → a karaoke backing track.
  • Instrumental OFF → just the singer.
  • Vocals turned down → sing along with a little guide voice.
• Drag the bar under the Play button to jump to any part of the song.
• Below the mixer, each stem also has its own player and a ⬇ Download link (MP3).
• The first time you press Play together, it loads both stems fully, which takes a few seconds on a slow connection.

Credits

• New accounts start with 10 credits. Each split uses 1 credit.
• You get 1 credit back every day, up to a maximum of 10.
• If a split fails, the credit is returned automatically.
• Your balance is shown at the top of the page, with the time until your next credit when you're below 10.
• Need more? Email dmakhija@nuvam.ai.

Storage

• Each account can keep up to 500 MB of stems. A typical song uses 10–25 MB, so that's roughly 20–50 songs.
• Your usage is shown at the top of the page. When the library is full, delete old tracks (✕) to make room. Space frees up straight away.
• The file you upload is deleted as soon as it's been split. Only the stems are kept.
• This is a demo service, so download anything you want to keep. We can't guarantee stems are stored forever.

Questions

Why does the progress bar stop moving while it's separating?

The separation runs on a cloud GPU that doesn't report its progress back to the page. The bar sits still for a few minutes and then jumps to Ready. That's normal.

My track failed. What now?

The error is shown on the track. Your credit has already been returned. Delete the track (✕) and try again. If it fails again, try a different file format (MP3 works best) or email us with the error message.

The upload says the file is too big.

The limit is 80 MB. Use a single song rather than a full album or concert, or convert it to MP3, which is much smaller than WAV.

Can I paste a YouTube link?

Not at the moment. Upload an audio file instead. Here's how to get an MP3 from a video on your own computer.

How good is the separation?

It uses a state-of-the-art AI model (BS-Roformer) and is usually very clean. Songs with heavy effects, reverb, or backing vocals may leave faint traces of one part in the other.

Can other people see my tracks?

No. Your tracks and stems are private to your account.

Can I delete my account?

Yes. Email dmakhija@nuvam.ai from the address you sign in with, and we'll remove your account and all your tracks.

Am I allowed to split any song?

Only submit audio you own or have permission to use, and use the results privately. See our Terms & Copyright.
