AI music separator: remove music and split stems
An ai music separator is the easiest way to do ai music removal without guessing. If you’ve used an ai music remover before, you already know the pain: sometimes you get a clean instrumental, sometimes you get “ghost vocals.” The trick is learning when to ai remove music from audio by splitting stems first, then adjusting what you want.
What an ai music separator does (simple explanation)
Most songs are a single “mixed” file: vocals + instruments all glued together. An ai music separator tries to unglue them into separate tracks (often called stems). That idea comes from audio source separation—a well-known audio field where models learn to separate overlapping sounds.
If you want the tool that does this on NeuralSound, start here: AI Music Separator.
Choose the split based on your goal (2-stem vs 4-stem)
This is the biggest quality lever. Pick the simplest split that still gives you what you need.
2-stem split (fast, usually cleaner)
Use 2-stem when you want:
karaoke-ready instrumental (vocals down)
vocals-only for practice
fewer artifacts in general
If karaoke is your main goal, you’ll probably end up using Karaoke Maker for the output.
4-stem split (more control)
Use 4-stem when you want:
separate drums / bass control
better results for remixes and edits
a cleaner balance for voice clarity (music bed down, voice up)
NeuralSound supports both of these separation modes.
The workflow that usually sounds the most natural
1) Start with a better source than you think you need
Separation models do better when the audio isn’t crushed:
WAV/FLAC beats low-bitrate MP3
if it’s from video, export audio at decent quality first
2) Separate first, then “remove”
A lot of people try to ai remove music with EQ alone. That can work a little, but music and voice overlap in the same frequency space, so EQ-only often damages speech.
Instead:
Split into stems (2-stem or 4-stem).
Lower the stem you don’t want (don’t always hard-mute).
Export the result.
Do tiny cleanup after (trim, light EQ, light leveling).
3) Balance beats “delete”
If your instrumental feels hollow, it often means you removed too much too sharply. A small amount of the vocal stem kept very low can sometimes sound more natural than a full mute (especially in choruses with reverb).
Common problems (and what to try)
“Ghost vocals” are still there
Totally common in reverby hooks and layered choruses.
Try lowering vocals instead of muting
If you’re on 2-stem, try 4-stem for more control over what’s bleeding
Drums leaking into the vocal stem
Use 4-stem
Lower drums slightly and re-balance rather than expecting perfect isolation
Output sounds thin
Add a bit of “Other” or “Bass” back
Avoid aggressive EQ unless you really need it
