Manual ensemble in UVR5 GUI

(more)

 

"You can use Colabs [or other sites, or already existing separations] to make individual model separations and then use the manual ensemble tool from UVR5 GUI to merge them together (you don't need special CPU/GPU to use that tool and it's fast! 15-year-old dual core computers can handle it).

 

In UVR GUI > process method = Audio Tools, then choose "Manual Ensemble" and the desired ensembling method."

 

Combine input is even more aggressive than Max Spec.

E.g. it takes two -15 iLufs songs, and makes a pretty loud -10 ilufs result.

To potentially deal with harshness of such output, you can set quality in options to 64 bit (sic!), or possibly manually decrease volume of ensembled files before passing through UVR Combine Inputs.

Combine input was good for ensembling e.g. KaraFan results of a preset with the least amounts of residues, and e.g. the preset 5 for more clarity, but a bit more residues. The instrumental result was fuller sound, better snares and clarity.

The downside is, you cannot control the gain of ensembled stems precisely like in DAW, or using Colab, and sometimes the resulting track gain might be higher than 1.00, so export as at least 32-bit float, so you can turn down the volume back to 1.00 in a DAW.

 

How to separate in UVR using multiple models in batch locally, to compare the results for the best manual ensemble?

 

Simply use Ensemble Mode, but before, go to Settings>Additional Settings and enable “Settings Test Mode” (adds 10-digits to every separation file name, so you won’t overwrite the result of the same models with different settings) and “Model Test Mode” (adds model name to every output file name, so the file won’t get overwritten by any other model separation) and now go to Settings>Settings Guide>Choose Advanced Menu>Ensemble Customization Options and enable “Save All Outputs” (now when you choose models to separate in Ensemble, intermediate files won’t be deleted, so not only min/max/avg mag ensemble result file will be left, but also result of separation from single models which you can use later to check the result manually for manual weighted ensemble e.g. in DAW or in Colab).
