Deep dive into stem separation tools?

Topic starter  

I was browsing again through the videos on the hitmix.com page, and the Youtube channel, looking into stem separation deep dives.

While the other tools are interesting, I bought the software - and all the upgrades, to be able to control and fix stem separation. Most videos veer between RipX's unique features, and those it shares with programs like Melodyne.

I'd love to see someone just go super deep into all the tools for improving a Ripx separation, how to move things between layers or channels in the best way, and so on.

There's lots of tools there, but I just feel clumsy using them, I really want to see someone who's mastered the program doing clever things.

Videos that veer into other features frustrate me, because I don't feel I'm ready to go into those features while I can still hear artifacts, or missing bits, and so on. It took me a while to convince myself to splurge on this, I'm sad I can't figure out the additional features in the upgrades. I'm still convinced that the upgrades are ace, but I do need to figure them out. 

And I'm skeptical spending time on watching the review type of videos, since those usually feature new users and a very skin-deep approach to the product. I watched a couple of them, but they just skimmed the surface. 

So my question is:

Are there videos that cover this, that I didn't find? 

If not, I guess this is a suggestion that learning material with this focus be created 😀

Thanks for your feedback and suggestions. 

You may be interested in these blogposts which cover deeper stem and noise clean-up capabilities using DeepAudio:

@dave There's so much more that I could learn about DeepAudio. To be honest I don't know if the tool is as robust as I thought - most of the videos online deal with Deep Remix and Deep Create, but not Deep Audio, the harmonic editor, etc. I tried separating some loud crowd noise from a video and could not figure out how to work with the harmonic editor - in the main window I can "split" a note (for example if I hear that Ripx has detected 2 different persons and one is far in the crowd, with their onset after the main person speaking. If I'm careful and select that point in the note where the main person's voice is ending and the crowd, then Ripx cleverly splits these and in so doing it recognizes that the pitch of the person in the crowd is not the pitch that Ripx chose for the note during Rip. Now I go into the harmonic editor because some of the NEW 2nd note (the person in the crowd) is a combination including necessary sibilance from the SH sound of the main speaker. But harmonic editor, unless I'm missing something, has no way to zoom, or audition the harmonic relationships (because they're chopped into very short durations and with my nerves I can't really select one row in the harmonics window (which is too small in size) to figure out which part is sibilance, and even if I did figure it out, my options there, unless I'm mistaken, do NOT include redirecting that harmonic material back to the original note.

@zenwarlord It sounds as though you are using an older version of RipX. I recommend using the most recent version which can be downloaded from: 

https://hitnmix.com/downloads

It's best to uninstall your existing version before installing this one. 

Unpitched sound that isn't contained within a note can be edited with RipX DAW PRO's 'Edit Unpitched' tool (which was also included with DeepAudio).

It's possible to resize Harmonic Editor by clicking & dragging the edges of its window. Making it taller will increase the height of each harmonic. If you select the first tool listed along the top of Harmonic Editor, you can click & drag over harmonics to listen to them. Harmonics can be removed from the currently selected note to another note by selecting the second tool from the left, checking 'Remove To New Layer', then clicking & dragging over them.

More information about Harmonic Editor can be found on pages 46-47 of the (most recent version of the) manual which can be opened from RipX DAW's Help menu.

@dave Thank you very much for responding. I'm using the newest version according to clicking on About and selecting Check for updates. 

I did notice that the Harmonic editor the resize capability exists, but the GUI has it so there's no border around the harmonic editor window, and I'm using a 3 screen monitor. The harmonic editor window has been opening past the right edge of my main window which in other programs would in one or 2 programs make recycle to the far left of the display group and appear on the far left display even if (as in this case) the main display is considered by Windows to be the farthest one to the right, but not so in Hit'n'Mix Ripx - it disappears into the void and so I couldn't see it. Nonetheless I did notice I could drag it's location and size yesterday. However, when i drag the size to increase it vertically to max, each harmonic is, if I'm guessing correctly, still only about 2 or 3 mm - but that IS big enough to edit, but not to split them the way I can do in the main window. So, for example, if there are 2 human beings captured in that same harmonic, even after splitting in the main window, then as you say I would be forced to create a new layer (combined voices) and paste it there - but that wouldn't be useful since one of the 2 voices is the speaker and another is a crowd member.

I wanted to learn how to copy to new layers anyway.  

I tried going through the steps of using the 2nd tool from the left but it didn't work - nothing happened. I tried holding down 2 (it doesn't say whether this is the main keyboard 2 or the number pad 2 so I'm assuming it's the main keyboard 2.) In trying to use the number shortcuts I then got "harmonic editor has terminated (line 668).  

I did also notice that after selecting the far left tool, there's a bit of help hints that indicates you can cut/paste, so I tried it, and the harmonic disappeared. I then tried pasting to a different layer, hoping that the note would appear there, but nothing did. 

Thanks again for responding!

@zenwarlord It sounded as though you were using an older version because you referred to DeepAudio which doesn't exist in the most recent version. To confirm, the most recent versions are 7.1.1 on Windows and 7.1.0 on macOS. 

Did you have 'Remove To New Layer' checked and 'Amount' set to more than 0%? Can you see a new layer in the Layers Panel and a new note at the position of the note you selected? 

The Harmonic Editor tools are for use within the harmonics of the currently selected note so cutting & pasting is of harmonics within that note. 

Is your computer a PC or a Mac and, before the message appeared, did you do anything other than press the keyboard shortcuts? For example, did you make any edits or click outside of Harmonic Editor?
