You can remove the bass from a music track by uploading your audio file to an AI stem splitter, which isolates the bassline from the rest of the mix. Once the track is split, you download the stems and combine everything except the bass.
Why remove bass from song files?
Many bass players want to learn a specific bassline by playing along with the original track. However, hearing your own instrument over the original bass can be difficult and confusing. If you remove bass from song recordings, you create a custom backing track. This allows you to play your own bass guitar along with the original vocals, drums, and other instruments without the original bassline clashing with your playing.
People also remove the bass when they want to sample a track for a remix or a new beat, but the existing bassline interferes with the new bassline they want to write. By isolating and removing that specific frequency range and instrument, music producers can keep the original melody, vocals, and percussion intact. While you might use a vocal remover to get an acapella or an instrumental maker to remove the vocals, removing the bass requires a tool that separates the rhythm section into individual parts. Creating a mix without the low-end frequencies gives audio engineers and DJs more control over their live sets and studio projects.
How do you remove bass from song tracks using AI?
To remove the bassline, you need to split the original audio file into separate parts, which are called stems. You can make yours using our tool, Stem Split AI. Our system uses Demucs htdemucs, which is an open-source model from Meta AI research. We run this model entirely on our own servers to process your audio files. This means your audio is processed directly by our hardware using the Meta AI research model.
When you upload a track, the AI processes the audio and splits it into five distinct stems: vocals, instrumental (which is the drums, bass, and other elements added together), drums, bass, and other (instruments like guitars, keyboards, and synthesizers). By separating the track into these five stems, the bass is completely isolated into its own file. To get a track without the bass, you simply take the vocals, drums, and other stems, and mix them together in your audio editing software, leaving the bass stem out entirely. You can also use this same process if you want to act as a karaoke maker by removing the vocals and keeping the bass, drums, and other instruments.
Before you commit to downloading the files, you can hear what the separation sounds like. Splitting and previewing are free. Every split plays a 30-second preview of all five stems. This preview starts at the 0:30 mark of your song. If your song is under a minute long, the preview will start from the beginning of the track instead. The 30-second preview usually comes in about a minute after you upload the file. This short wait time allows you to quickly verify the quality of the isolation. If you decide to process the entire track, a four-minute song is fully split in about three minutes. The exact time will depend on the length of your song, up to the maximum limit of 10 minutes.
What file formats and sizes can you upload?
When you are ready to split a track, you must provide a direct audio file. You can upload an MP3, WAV, FLAC, M4A/AAC, or OGG file. The file size can be up to 90 MB, and the song can be up to 10 minutes long. We do not accept links to external platforms, so links such as YouTube are not accepted. You must have the actual audio file on your computer or device to upload it. If your file is larger than 90 MB or longer than 10 minutes, you will need to trim or compress it before uploading.
The quality of the stems you get back will depend on the quality of the file you upload. A high-quality WAV or FLAC file will generally yield cleaner results than a heavily compressed MP3. Regardless of what you upload, it is important that you have the legal right to process the audio. If you are uploading a track, you must ensure you have the necessary permissions to split and download the stems. Any copyright notices should be directed to contact@stemsplitai.com.
How much does it cost to download the stems?
We offer a system where you can test the AI separation before you pay. As mentioned, splitting and previewing are free. If you do not have an account, you can split 1 song a day for free. If you are signed in, you can split 5 songs a day for free. This allows you to check the 30-second preview to ensure the bass is separated to your liking before you spend any money.
If you want to download the full stems, you will need to use credits. Downloading a whole song costs 125 credits, which equals $0.50. For this price, you receive all five stems. You get these stems in two formats: MP3 (at 320 kbps) and WAV (at 16-bit, 44.1 kHz). The WAV files provide uncompressed audio, while the MP3 files offer a smaller file size for easy sharing and storage.
To get credits, you make a one-time purchase. A $5 purchase adds 1,250 credits to your account. Because each download costs 125 credits, this $5 purchase is enough for 10 songs. There is no subscription required, and you do not have to pay a monthly fee. Credits are only spent on a download. You only spend credits when you choose to download the full stems after hearing the preview. All payments are securely processed through FloatPass. You can learn more about how the credit system works on our pricing page.

What happens to your files after you split a song?
When you use an acapella extractor or a stem splitter, you might wonder where your audio files go and who has access to them. At Stem Split AI, files are only available to the person who uploaded them. No other users can access your original uploads or the stems generated from them.
We have strict deletion policies to manage the files on our servers. The original audio file you upload is deleted after 1 day. The stems that the AI generates are deleted after 7 days. This gives you a full week to download your MP3 and WAV files after you spend your credits, but ensures that the data does not remain on our servers permanently. If you need the stems again after 7 days, you will need to upload the file and process it again.
What other tools do people look at?
When searching for ways to process audio, remove bass, or isolate instruments, people often look at a variety of different websites and software documentation. Some of the places people also look include moises.ai, lalal.ai, manual.audacityteam.org, help.moises.ai, isolate.audio, and podcast.adobe.com. Each of these domains represents different approaches or tools that users explore when working with digital audio files. While these sites are common destinations for audio editors, our tool focuses strictly on providing a straightforward, pay-per-download stem separation service using the Demucs model on our own servers. We provide the specific five stems you need to separate the bass from the rest of your music.
