Remove Vocals From Any Song and Make Your Own Karaoke Track
If the karaoke version doesn't exist, you can make it. A stem splitter removes vocals from any song and gives you a clean instrumental in a few clicks. No
Maybe you have a song you always pick (it's the only one you know the lyrics to), but there is just no karaoke version that you are able to find. Put simply, you have a song in mind, but there are vocals on top that ruin the purpose you have for it.
Luckily, it's an easy and fixable problem, and you don't need to know anything about audio or software to solve it. Stem splitting takes the vocals or other components out of a song and gives you clean, isolated tracks. When just vocals are removed, it's basically a karaoke instrumental, and it is easy to get a quick, singable version with little effort.
What Is a Stem Splitter?
Stem splitting is the process of taking the original mixed song and breaking it back into its individual parts. These “parts” are called stems, and vocals are a type of stem. The above graphic is a clear visual representation of this process. Often you can also extract stems such as drums, bass, and other elements. The focus here, however, is removing just the vocal stem from the track.
These tools analyze the audio to learn how to separate vocals from the surrounding instrumentation. The separation is remarkably clean if the track provided is clean and not too noisy.
How to Remove Vocals From a Song With Lalals
Lalals Stem Splitter is an online vocal remover that handles this without any software to install or settings to learn. The whole process takes a few minutes.
Step 1: Go to lalals.com/stems
Visit Lalals stem splitter tool, and when you sign up, you also receive free credits so you can actually try the tool out for your first karaoke track.
Step 2: Upload Your Song
To process the music track, you have three options: Upload the audio file directly, record audio on the spot, or paste a YouTube link. That YouTube option is worth taking note of, as many usable tracks exist on YouTube, so you don't need to download anything first. For that option, just paste the link and the tool pulls it in.
Step 3: Select Your Stems & Click Extract
This is the step to tell the tool what it is to extract. For a karaoke purpose, the selection is simple: check "Instrumental" and leave the rest. The options do go deeper than that (if you need to). Vocals can be split into lead and backing or by gender (which is notable if there are male/female lead and backing vocals). It can also break down individual audio elements like kick, snare, hi-hat, piano, guitar, and bass. For karaoke purposes you won't need most of that, but it's there.
When everything is as you want it, you simply click the “Extract” button and let Lalals process the stem splitting for you. The time varies depending on the length of the track, but on average it’s around one minute.
Step 4: Download Your Files
Once processing is done, each stem comes back as its own downloadable audio file. Download the instrumental, and that's your karaoke track. All without DAW, plugins, or audio engineering knowledge.
A well-produced song will split more cleanly than something with a lot of bleed between the vocal and the instruments (Think like live recordings, highly compressed files).
One Thing Worth Knowing
A highly compressed MP3 will often split in less clean ways than a lossless file. This is why it's best to use the highest quality version you have access to. It's not always a dramatic difference, but it's worth using the better file if you have it just to be safe.
Personal vs. Commercial Use: Creating a personal karaoke version to sing at home or a party is one thing. Distributing it or using it commercially is a different question, and one worth looking into before going further than personal use. In such cases, consider our section on making your own karaoke song
What to Do With Your Karaoke Track
What you do with the instruments depends on the situation.
For a casual karaoke night at home, the simplest setup is playing the file through whatever speaker or sound system you have, with someone singing over it on a mic or even just unplugged. If you want lyrics on screen, pairing it with a free lyrics display app like Karafun or SingStar are common options.
If you're running a more organized karaoke night, the bigger upgrade is building a small library of tracks ahead of time rather than tossing it together the night before. Pull the instrumentals for the songs your group reliably requests, label them clearly, and have them ready.
Make Your Own Karaoke Song
It’s worth considering if your party is up for a little roast or humor, you can easily create your own songs for karaoke night. You can use common AI tools like ChatGPT or Claude and feed them a bunch of ideas and information on you and your friends to help come up with a parody/joke song to sing along to as a surprise. Lalals itself has a lyric generator tool that could help you with this too. Just input your ideas, funny memories, and inside jokes, and have it turn into a song!
Other Ways to Use a Vocal Remover
Making karaoke tracks is the simplest use case, but the same problem comes up in other places for similar reasons. Singers who want to post a cover on TikTok, Instagram, or YouTube and need an instrumental to record over. People practicing seriously want to hear their own voice without the original artist singing over them the whole time. A clean stem-split process turns that into an actual instrumental version without all the vocals or other things in the way.
This is to say, the need isn't unique to karaoke nights. It's for anyone who needs the song without the vocals or a specific component within it, ruining the purpose.
Get the Karaoke Version of Any Song
The barrier is quite simply getting an instrumental version of it you can actually sing along to. Stem splitting offers a solution that has not really existed until now. So, whatever's in your library, whatever someone made for you, and whatever you've been searching for a karaoke version of for years, upload it, pull the vocals out, and you're done.
