Introducing HQ Fusion
HQ Fusion uses one advanced AI fusion pass to deliver cleaner vocals and cleaner instrumentals from the same song.
Compared with our standard Vocal Remover model, HQ Fusion is designed to leave vocals clearer and instrumentals cleaner, while keeping the experience simple for the listener.
HQ Fusion is built to reduce leftover accompaniment in the vocal stem, helping lead parts sound cleaner and more focused.
Because the vocal estimate is cleaner, the instrumental output can preserve more of the backing track without pulling vocal traces along with it.
Benchmark gains
Compared with our standard Vocal Remover model, HQ Fusion delivered measurable SDR gains on our validation set.
Cleaner vocal extraction compared with our standard Vocal Remover model.
Cleaner backing-track separation compared with our standard Vocal Remover model.
SDR (Signal-to-Distortion Ratio) is measured in dB, so we show the direct SDR gain instead of percentages.
Why one fusion helps both outputs
HQ Fusion creates one improved vocal estimate and uses it as the foundation for both outputs. That means the same upgrade that helps the vocal stem also helps the instrumental stem.
Instead of asking you to choose between separate tuning options, HQ Fusion gives you one polished mode designed to improve full-track separation in a straightforward way.
It is a good fit when you want a cleaner overall result without needing to think about what happens behind the scenes.
What changes in practice
Vocals are easier to work with when you want fewer backing remnants and a cleaner lead performance.
Instrumentals can sound more consistent because less vocal residue is carried over into the music-only output.
You simply choose HQ Fusion and run your track. The upgraded processing stays behind the scenes.
If the additional processing step fails for any reason, the system falls back automatically so your conversion can still complete.
