Any tips for improving extraction of live vocals from a crowd

I’m working on some very challenging audio from an iPhone capture of a gig. The band need me to clean it up and add some underlayers to enhance it. There was no desk audio and the crowd were noisy. The unmix crowd noise has done a decent job but theres a good bit of the needed lead vocals in the crowd layer. I’ve been drawing areas and moving them to the foreground layer but its very time consuming.

I was also trying the frequencty select tool and to less success the harmonics tool. I’m not sure of best ways to get useful results from that.

The layers are fairly modulated/watery sounding but still can work wtih it

Anytips for this kind of job with Spectralayers?

Maybe an Unmix Mid/Side of the crowd layer could help you?

And perhaps another round with Unmix Crowd on each of those two resulting layers?

I would start with Unmix Noisy Speech and see what that yields

I find the tools that are tied to amplitude like Freq/Harm selection, Magic Wand tend to make too narrow of selections and you need to adjust parameters to get something usable

I find the free selection tools give better results for my uses
I also find the harmonic selection tool can wander if you have a lot of harmonics being selected

yep, it is very, very time consuming.
If you have the lead vocal somewhat separated, then use that as a key for selection rather than free-handing (mousing) in the noise layer. I typically use magic wand and brush tool on the separated speech/ voice layer to build up a selection and then switch to the noise/ crowd layer to edit from. When selecting on the noise layer, you can get lost in the noise.

Also, remember ctrl+shift+D (win) for re-selection of previous selection.

Just trying help, good luck
