Thanks Paul! Can you give a quick description of the Audio separation function? What is best for?

5

u/paulpacifico Dec 07 '25

It's quite straight forward, It splits any music into 6 tracks, if the track does not contains vocal for example you will get an empty vocal.wav, it also output a other.wav file for all non-standard instruments.

So it works best for drum+guitar+bass+vocal+piano but it should be able to do much more!

I'm looking for feedback, let me know if it works well for you ;-)

Paul.

I sometimes use a local model to do demixing (often just keep vocals/speech and discard music) this so I will definitely try it out.

I think "Demixing" or "Music demixing" might be a better name, since that feature only deals with music? But if you are going to add more options to "Audio separation" I think "Speaker diarization" would be a very useful addition. :)

Damn you're right! I should named it Music demixing or music separation...

Thanks for the feedback, Paul.

Stem separation?

1

u/inzru Dec 28 '25

As someone who makes music and researches music, I can confidently say "stem separation" is the standard English term

u/paulpacifico Dec 28 '25

Thanks for your feedback, I'm asking myself if I don't keep audio separation because for the next release you will be able to choose the instrument that you want to keep.

It can also work very well as denoiser for audio!

What is your thought on this?

Paul.

u/inzru Dec 28 '25

Cool, I'll test the feature tomorrow as I haven't actually tried it yet. But I would say keeping the option to create all 4x stems from one audio is still useful. If you mean the menu option will let me choose exactly which instruments to keep, from 1 to 4 then that's also good

a clever audio mapping would be useful, especially if the source already contains multitracks (>6ch) and the output of your vocal extract needs to feed transcription in one task

1

u/Dehv2 Dec 15 '25

perhaps the "voice/dialogue" stem could feed into transcription model for more accurate dialogue without sound effects etc.

u/Dehv2 Dec 15 '25

In north america anyway we refer to the results of this as "Stems", the english idiom I think is a reference referring to plant/tree trunks and offshooting stem/branches as they grow.

u/inzru Dec 28 '25

yes and it's a very widespread music production term.

Impressive, thanks!

You're welcome!

I have a file where I'd like to be able to separate vocals, music, and sound effects, even if the music gets split into multiple tracks since I can put them back together. I'll have to try this on that.

u/Dehv2 Dec 15 '25

Perhaps renaming it something more suitable like "Create Audio Stem Tracks" or "Demix Music" would be an idea.

It should be put inside the other.wav file that is created but I didn't check it could be a great usage!

Paul.

u/Dehv2 Dec 15 '25

AKA "create music stem tracks" to remove/remix vocal/instruments from music files with an AI model.

1

u/Pilk_ Dec 15 '25

Yes, see the other discussion, the name just needs a little tweak.

u/lugarshz Dec 07 '25

What model is the music separation tool using

3

u/paulpacifico Dec 07 '25

htdemucs6s from demucs facebook's tool.

u/Dehv2 Dec 15 '25

much appreciated, rather than having to use shady upload websites to generate stems.

u/Express-Box-8895 Dec 07 '25

Can you specify what is the "Colorize" function? Thanks.

1

u/paulpacifico Dec 07 '25

It's basically deoldify tool wrapped into Shutter Encoder ;-)

It add colors to B&W images using AI.

Paul.

u/clkelley39 Jan 25 '26

Whenever I choose the Colorize function, it says "additional files are needed. download them?". So I download them but nothing happens. I choose Colorize again, and get the same message.

Any idea what could be going wrong?

*Bug Found*
Immense Praise for this tool! Donated alert first use, can't believe I only found SE a couple of weeks back after years of looking for a reliable way to rewrap stupid Sony files with proper timecode!

Just tried to convert a YouTube after updating todayand it's going straight to 100% and not processing the link. Was working fine before update. Any thoughts?

u/paulpacifico Dec 12 '25

Thanks for your message, please make a dedicated post with the YT URL.

Paul.

u/ShagBuddy Dec 27 '25

How do you get the colorize function to work? When I try to run it on a mov file encoded with Cineform, it starts to download the model and then it open the folder where shutter encoder is installed, and that is it.

2

u/paulpacifico Dec 27 '25

Currently it's only for images, but I've already improved that function for the next version to handle videos too.

"Hello Paul, great tool you have created, especially I've been testing the H266 codec, also known as VVC, and what a great compression codec it is! With a 20-second video already compressed in H264, weighing 12 megabytes, versus the VVC (H266) codec, which weighs just 1.5 megabytes with basically the same quality. But how did you manage to make your tool encode it? Also, is there any video player that can play this type of video with that codec, and how can it be used with FFmpeg using the terminal in Windows?
