Separation beats filtering
Classic noise reduction carves frequencies out and takes the voice with them. Stem separation pulls the voice out as its own track instead, which is why it sounds natural.
What comes back
An isolated voice track plus the leftover parts. Keep the voice, discard the rest, or mix a little room back in if it sounds too dry.
Where it helps
Interviews recorded in cafes, phone calls, podcasts with a fan running. Any footage where the moment was right and the room was wrong.
FAQ
Will it remove music behind speech?
Yes, that is exactly what separation does. Heavy overlap leaves faint artefacts.
What files work?
MP3, WAV and M4A up to 30 MB.
Is it the same as the stem splitter?
Same engine, different intent. The splitter is for music, this page is for cleaning a voice recording.
