How to Reduce Background Noise in FL Studio Vocals

Steady hiss or hum can distract from a vocal before you even start mixing. In FL Studio, Edison has a Noise Removal Tool for continuous background noise. Use it carefully: heavy cleanup can also affect quiet details in your take.

First, identify the noise

A constant hiss or electrical hum is different from a click, keyboard sound, or door closing. The official Image-Line guide says Edison’s Noise Removal Tool is intended for continuous noise, not short, changing sounds. If the sound comes from your room or recording setup, fixing the source or recording a cleaner take may give you a better result.

Try Edison on a copy of your vocal

  1. Open the vocal recording in Edison and find a pause where only the background noise is audible, if your take has one.
  2. Open Edison’s Clean up (denoise) tool and acquire a noise profile from that noise-only section. Image-Line’s guide explains the controls and where to find them.
  3. Preview the cleanup. Use “Output noise only” to hear what the tool is removing.
  4. If you hear parts of the voice in the removed sound, back off. The goal is to make the noise less distracting, not to erase every trace at the cost of the performance.
  5. Compare the processed take with the original at a similar listening level before you keep the change.

If you cannot find a section with only noise, be more cautious. A tool cannot always separate a changing sound from a vocal that overlaps it. Avoid processing the only copy of your recording so you can return to the original if the cleanup sounds unnatural.

Clean recording first, vocal mix second

Noise cleanup and vocal mixing solve different problems. Edison may reduce steady background noise, but it does not place a vocal in the beat or create its final tone. Once the take is under control, build the mix around your voice and check it in context with the instrumental.

If you want a prepared starting point after cleanup, take a look at the Frenna Type vocal preset bundle. It has an FL Studio option available in the US store. A preset is a starting point for shaping your vocal, not a noise-removal tool or a guaranteed finished mix.
