What I want to point out is that drawing such a general conclusion from such a particular case makes little or no sense to me. If someone really wants to compare the different algorithms available on the market to figure out which oneis ‘the best’ for bass, then it would be necessary to compare not one or two examples, but a large number of them, with different audio qualities, different mix qualities, from different eras, different compression ratios, different styles of playing, different bass sounds and techniques, different panning, etc. And of course, if this job is going to be made by different people, the test files must be identical for all of them; posting a youtube link and expecting that everybody else will download the same mp3 with the same quality from that link is probably not a realistic idea.

Bearing in mind that (as far as I know) the vast majority of available algorithms actually use the same common code (derived from the Open Source Spleeter -or, in some cases Demucs-) and differ from each other basically in terms of the amount and quality of material they have been trained with, the result of such an experiment would probably be that there is no ‘best’ algorithm in a broad sense. Some of them would simply work better in some cases than others, and viceversa.

It seems common sense to me that an AI trained mainly with classic jazz material will do a better job separating Paul Chambers' double bass line ion "So What" than another AI trained mainly with 70s funk. I think that the next generation of stem separation programs will allow the user to choose between different trained models, depending on the starting material.

Cerio, I have no time or desire to do the exhaustive investigation work that you propose. The two conclusions that I am drawing are as follows:

1. Studio One Pro ver 7 has produced a state-of-the-art stem separation capability for bass that is second to none. I now have a wonderful new tool in my toolbox that meets my needs in this regard.

2. No one on this forum has demonstrated a program that has a bass stem separation capability superior to that of Studio One Pro ver 7.

Because of these conclusions I'm moving on to other things.

However, I encourage you to personally perform the very comparison work that you propose. I’ve given you a head start on this with a list of programs at the top of this thread. I’ve even given you a good “tuba test case” that you can use for part of your comparison work. I also encourage you to share your results and conclusions here on the forum. And if at the end of your study you find that your conclusions differ from mine, great. Learning something new is good.

My instincts rarely fail me and they are telling me that you will decline to do this work.
My hope is that you can prove my instincts wrong.

PS> A spreadsheet may be a good way to organize your results.

For me there’s no better place in the band than to have one leg in the harmony world and the other in the percussive. Thank you Paul Tutmarc and Leo Fender.
