There is no native Vegas Pro audio FX that can do voice isolation in a similar way as far as I am aware - most of VP's audio FX have been around for a decade or more (though the ExpressFX ones are more recent).

Steinberg have just released SpectraLayers Pro 10 that comes with giant leaps forward in unmixing using AI. Unmix options include unmixing noisy speech and unmixing multiple voices. Have a look at SpectraLayers Pro 10's webpage for more information - https://www.steinberg.net/spectralayers/new-features/ - and check out the demos attached to each feature's listing.

The tests I've done with SL10 at unmixing vocals from songs had spectacular results - much much better than was possible in SL9.

SL10's developer advised on SpectraLayer's forum about a week ago that the first update to SL10 (to be released next week) includes GPU unmix assistance thus enormously speeding up unmix processing. From another SL forum thread, apparently GPU assistance with unmixing noisy speech will come with the 2nd update later this year.

SpectraLayers Pro 10 (the version which has unmixing) is not inexpensive but is much lower in cost than iZotope's RX Advanced which has its own version of voice isolation. Further, crossgrading to SpectraLayers from RX5 or above (Standard or Advanced) as well as from Adobe Audition comes with a discounted price.

Unfortunately, there doesn't seem to be a trial version of SL10 available at this time.

Hello,

 

I don`t have Davinci Resolve, but I know that there is an audio effect called "Voice isolation".

Do you know if such similiar audio effect is available in Vegas Pro 20 or maybe you know if such audio effect is going to be released in nearest Vegas Pro upgrade.

There's a free one https://github.com/werman/noise-suppression-for-voice

I compare original/Resolve's Voice Isolation/RN noise suppression

Note that it's a compromise between keeping the voice 100% intact with removing the highest amount of noise.

In the Resolve example, I missed the distorted 'after' so actually I probably should have allowed more noise in an attempt to have a non distored 'after'. With RN noise suppression I allowed a lot more noise then I would have wished but still the Voice is distorted. It may have a use in limited noisy circumstances

Might also be worth a look: https://podcast.adobe.com/enhance#

SpectraLayers Pro (SLP) used to have a full functioning 30-day trial, I do not know if the trial is still available. Otherwise SLP is my go-to app for restoration. Not exactly a budget item, but lower cost than iZ's RX 10 Adv. (which is also good).

The trial for SpectraLayers 10 will be available next week. Meanwhile, you can check this page comparing SpectraLayers 10, RX 10.4, Acoustica 7.4 and Clarity Vx 14 on different denoising/restoration tasks : https://divideconcept.github.io/Restoration-Comparison/

@marcinzm Resolve Voice Isolation does a really good job of eliminating wind noise. That's what I use it for. There's no effect in Vegas 20 that can do as good a job. For some other types of sounds that Resolve doesn't handle well, I use Adobe Audition Sound Removal or Noise Removal.

Audo . ai allows 20 minutes of audio processing each month using AI. The demo is pretty incredible, I've used it a couple of times with good result, but not as good as the demo. It's not inside Vegas, you upload your audio, download the processed version and manually replace on timeline.

@wjauch That does do a good job, a little raspy but none of the ones I compared were perfect either

Vegas isn't using AI for audio... Yet... But some really cool video tools are coming soon, stuff that goes beyond the AI tools already present, and is useful to everyone. You'll hear more about that in the very near future.

NVIDIA also has a noise removal app- never tried it so don't know how well it works: https://www.nvidia.com/en-us/geforce/guides/nvidia-rtx-voice-setup-guide/ [Appears to work at the streaming/recording stage vs in post]
