- Karaoke at home. Sing along to the instrumental. StemNook gives you an audio file only: it doesn’t add on-screen lyrics or make a CDG.

Free vocal remover limits and downloads
Check these before you choose a file.
- Free access: Separation requires a Google sign-in. A free account gets 600 seconds (10 minutes) of processing per calendar month. That’s a monthly total, not a per-file allowance, and it isn’t unlimited. The month follows UTC, so it may start at a different local time than yours.
- How time is counted: Processing time is reserved using your audio’s duration, rounded up to whole seconds, not how long the cloud takes.
- Your file: MP3 or WAV, up to 30 MB, from 0.5 seconds to 5 minutes long.
- Where it runs: In the cloud. Your audio is uploaded for processing, not separated on your device.
- What you get: Two tracks, Vocals and Instrumental, which you can play and download separately as WAV (44.1 kHz, 16-bit, stereo). There are no MP3 downloads.
- How long you have: Free-account results are available for 24 hours after processing finishes.
New cloud tasks keep results for 24 hours on Free, 7 days on Pro, or 30 days on Studio. The expiry shown with each task stays fixed when you open it or change plans. Reusing the same available result does not use more minutes.
How to remove vocals from a song
You’ll need an MP3 or WAV that you own or have permission to edit. Then it takes five steps.
- Choose your MP3 or WAV. Pick a file you have permission to edit that fits the limits above.
- Click Start separation. Sign in with Google if needed, then return here and start when you are ready.
- Start the separation and wait. The AI splits the music from the vocals into two tracks. Wait until both results appear.
- Listen before you download. Play the instrumental first, then the vocals track to hear what was taken out.
- Download what you need. Save the instrumental as a WAV file. The vocals track has its own download.
Listen to the instrumental and compare it with your original
A short listening check is the quickest way to judge a result before you download it. Play your original in your usual audio player and the Instrumental track in StemNook. Compare the same section in each.
A five-step listening check
- Pick your checkpoints. Mark a verse, a chorus and the ending in your original, and note where each starts. For a clip shorter than 20 seconds, listen from beginning to end.
- Play the verse in both files. Is the lead vocal gone, or can you hear a faint ghost of it behind the music?
- Play the chorus. Layered harmonies and dense arrangements give separation more to untangle, so listen closely here.
- Play the last 20 seconds. Fade-outs and final chords are easy to skip, and vocals can still be audible there.
- Play the Vocals track. It shows what the tool took out. If you hear instruments in it, parts of the music may be missing from the instrumental.
If something sounds off
A different version of the same song may separate differently, so try another mix or file if you have one. If only the final seconds are affected, you can trim them off in an audio editor.
MP3 and WAV audio formats
StemNook accepts MP3 and WAV files only. Other audio formats, video files and web links aren’t accepted, and downloads are WAV files, not MP3.
What WAV does and doesn’t mean
WAV is an uncompressed format, but that doesn’t make the separation lossless. The AI estimates the vocals and the instrumental from a finished mix, so the instrumental isn’t the song’s original backing track, and the result isn’t guaranteed to keep your file’s original encoding.
File sizes to expect
A WAV at 44.1 kHz, 16-bit stereo takes about 10.6 MB per minute. Based on the format, two tracks from a four-minute song would take up about 84.7 MB, so check your storage before downloading on a phone.
The same math applies to uploads. A WAV of this kind reaches the size limit at just under three minutes, well before the five-minute limit. If your WAV is too large, trim it or export an MP3 copy first.
Karaoke, practice and authorized edits
An instrumental is useful whenever you want the music without the singer.
- Practice. Learn a vocal line, rehearse a cover or play along without the original singer.
- Authorized edits. Build on a song you own or have permission to change, such as your own recording or a licensed track. The Vocals track is available too if you need the singing.
Removing vocals doesn’t change who owns a song. Use only audio you own or have permission to edit, and check the rules before you share, post or perform the result. This isn’t legal advice.
Vocal remover artifacts and quality limits
AI separation estimates two tracks from one finished mix. Results vary from song to song, and a track may not come out fully free of vocals.
What artifacts can sound like
- Leftover vocals: a faint voice, breath or echo behind the music.
- Bleed: pieces of the instruments in the vocals track, or pieces of the voice in the instrumental.
- Reverb tails: room or hall echo that lingers after the voice is gone.
- Metallic tone: a thin, ringing or watery edge on some sounds.
What this tool doesn’t do
- It makes two tracks, vocals and a combined instrumental, with no separate drum, bass, guitar or piano tracks.
- It doesn’t promise to keep lead and backing vocals apart.
- It can’t recover a song’s original multitrack recording.
- It isn’t built for separating speakers, cleaning up noise or removing laughter.
Cloud processing and access
AI separation uploads your audio for cloud processing. Free-account results are available for 24 hours after completion, so download the tracks you want to keep.
Vocal remover not working: checks before retrying
Start with what you see. These checks apply to StemNook only.
- A file is rejected. Use an MP3 or WAV between 0.5 seconds and 5 minutes, up to 30 MB. WAV files reach the size limit first, so trim a long WAV or use an MP3 copy.
- Sign-in doesn’t work. Make sure you’re signed in with a Google account, then choose your file again if the page asks.
- You see a message about processing time. “This file needs more processing time than you have left this month” means the file is longer than your remaining allowance, even if some time is left. Try a shorter file, or wait for the next calendar month.
- Progress can’t be checked. A weak connection or a temporary error can stop progress from updating. Wait a moment and check again before you start another separation. Starting the same song again may use more of your monthly time.
- The separation failed. The tool will tell you. Check that your file meets the limits above, then try again. A new attempt is a new separation.
- Results have expired. Free-account results are available for 24 hours. After that, choose your file again to start a new separation.
If the result plays but sounds wrong, see the artifacts section above.
Vocal remover FAQ
Is this a free AI vocal remover?
It’s free within a limit. You sign in with Google, and each free account gets 600 seconds (10 minutes) of processing per calendar month. That’s a monthly total, not a per-file allowance.
How is my free processing time counted?
It follows the length of the audio you submit, rounded up to the next full second, not how long the cloud takes. When you start a separation, that time is set aside from your monthly allowance.
Can a file be refused even if I still have free time?
Yes. If a file needs more processing time than you have left this month, it can’t be separated, even if some time remains. Try a shorter file or wait for the next calendar month.
Is there an app to remove vocals from a song?
StemNook isn’t a native app. It’s a web page you open in your phone or computer browser, so there’s nothing to install. Mobile browsers handle uploads and downloads differently, so if something fails, try another browser or a computer.
Can I download an MP3 instrumental?
No. Results download as WAV files. If you need an MP3, convert the WAV with another tool.
Can I trim the instrumental afterwards?
Yes, as a separate step. Download the WAV and trim it in any audio editor.
What if my song is longer than 5 minutes?
The tool accepts tracks up to 5 minutes. For a longer song, trim the section you need in an audio editor and upload that part.
Is it okay to remove vocals from a copyrighted song?
That depends on the song’s rights, where you live and what you plan to do with the result. Practicing privately is different from publishing or performing. This isn’t legal advice.
