I have look all around for tutorials about isolating the vocals from a song. There is good material and i have tried several of them.

I obtained the best outcome by combining two tutorials, one mainly based on the Voicetrap plugin for FL Studio, and the other using Audacity.

For reference here are the two tutorials used:




(the paragraph is: A technique using Audacity for vocal isolation)


I have to say, they did a pretty good job.

The problem is that it remains a nasty robotic sounds in the background that in the end it make it not suitable to use it.

I have tried to make some several test trying to cover that background sounds, but you can hear that is still there and honestly it ruins everything.


How can i remove that robotic background sound that remains after isolating a vocal?
There must be a way no?
At least to clean it a little bit more?

I am using FL Studio 12 and Audacity, but i am open to trying other software if needed.

Thank you very much!

  • Can you include a sample in your question? Otherwise it's difficult to know what you mean by "robotic background". You can use SoundCloud. – Tom Cat Dec 7 '15 at 21:44

    If the sound is noise-like, you can use a denoise process. If it's not, you can remove unwanted sounds harmonic by harmonic using a FFT editor. You can do both in Izotope RX. – Tom Cat Dec 7 '15 at 21:57
  • By robotic background i mean what is left after working on the track by isolating the vocals. That youtube video is a perfect example. It does that process two times and both times it remains this robotic background. – FrancescoMussi Dec 8 '15 at 7:23
  • What do you mean by using SoundCloud? What is the best solution for a good denoise process? Audacity, FL Studio or something else? – FrancescoMussi Dec 8 '15 at 7:24

    You can upload your audio to souncloud.com so you can link it to us so we can hear exactly what's going on. Describing audio with words can be futile. Once we hear it we can help you. The software and technique you'll use depends on that. At the very least give us a time stamp on that 8 minute video, but that won't be as helpful. If you give us audio to download we can work on it and explain you what we did. Otherwise you are betting on someone to find it in that video, download it, edit the relevant part, and only then start working on cleaning the audio. Help us help you. – Tom Cat Dec 8 '15 at 7:38
