Vocal & Instrument Separator Online — Free AI Stem Splitter
The Voice & Instrument Separator uses artificial intelligence to split a music track into individual stems — vocals, drums, bass, piano, and more — so you can isolate or remove any part of a song completely online, for free.
What is stem separation?
Stem separation (also called source separation) is the process of isolating individual audio components — such as vocals, lead instruments, bass, and drums — from a mixed music track. Traditionally this required the original multi-track recording from the studio session. Modern AI and machine learning models can now approximate this separation from a finished, mixed audio file by learning the characteristic sound signatures of each instrument type.
The result is a set of separate audio files called stems. Each stem contains one isolated element of the song, allowing you to work with it independently. Quality depends on the complexity of the original mix, so some bleed-through between stems is normal.
What can you use stem separation for?
- Karaoke track creation — remove the lead vocal stem to produce an instrumental backing track.
- Music practice & learning — isolate a specific instrument (e.g. bass or drums) to study or play along with.
- Remixing & mashups — extract clean vocals or instrumental parts to use in a new production.
- Transcription — isolate a single instrument to make it easier to transcribe notes or chords by ear.
- Audio restoration — separate elements before applying noise reduction or EQ to individual stems.
Supported input formats
The tool accepts the most common audio and video formats, including MP3, WAV, FLAC, OGG, M4A, AAC, OPUS, and WMA, among others. After processing, each stem is made available for download as a separate audio file. Because the AI analysis is computationally intensive, processing times of several minutes are normal, especially for longer tracks — please keep the browser tab open until the job completes.
Frequently asked questions
Is the voice and instrument separator free to use?
Yes, the tool is completely free to use online. No account, subscription, or software installation is required.
How long does the separation process take?
AI stem separation is computationally intensive. Depending on the length and complexity of the track, processing typically takes several minutes. Keep the browser tab open until all stems have finished downloading.
Which stems or tracks can the tool separate?
The tool can isolate vocals, drums, bass, piano, and other instruments, delivering each as a separate downloadable audio file.
What happens to my uploaded file after processing?
Uploaded audio files are processed on the server solely to perform the separation and are deleted automatically afterwards. They are not stored permanently or shared.
Will the separated stems sound perfectly clean?
AI separation quality is very good but not perfect — some bleed-through from other instruments may occur, especially in densely mixed recordings. Results depend heavily on the original mix.
Can I use this to create a karaoke track?
Yes. Simply discard the vocals stem and keep the instrumental stems, or use the dedicated Karaoke tool on Conversion-Tool.com for a streamlined workflow.
