Hi all, I want to auto-split lots of samples from a continuous recording. These are from a stereo mic pair plus a mono pickup. I have used the auto-split function with great success before, but since I now have three channels, it does not work without disturbing the phase relationship between the two sources. Unfortunately, it looks like auto-split is not available for audio montages. Has anyone figured out a way around this?
Btw, I found this topic:
But I can’t figure out how I would copy markers to another audio file.
Thanks for your input!
The above option is available in the Marker tool window, but pasting depends on where your cursor is.
It is not clear if you are having a 3-channel audio file or one mono and a stereo file.
If it is 3 channel audio and you want to phase correct/align, you can open the audio file in the audio editor, create audio montage from audio file. In this case you have your channels split to move in the montage.
In the Montage, you can align phase/match start points, add markers and render as 3x file while keeping the option of copy markers checked and render whole montage.
Then you can use auto split on the phase corrected/aligned audio file, if you intend to split according to marker.
If you do not want to use auto split, you can create regions in Montage and render.
These are two ways to go about it; there are other auto split options and workflows but that depends on what samples you are working with to detect silence etc.
Thank you, there’s lots to explore here. So my source material is one stereo audio mic track and one mono audio track from a pickup. In terms of phase, these should be treated as three channel audio, but in terms of file management, these are two independent files and should render as such for use in the sampler instrument eventually.
In the audio montage, I don’t think I have the option of auto-splitting. Setting split points manually in the audio montage, while possible, is too laborious for the number of samples I’m looking at and I would want to avoid it if I can.
Edit: I just saw that what you pasted was a video. So I could import presumably import, say, the mono file, auto-split that, render, then copy the markers before closing the file and opening the stereo audio, then paste the markers? I’ll have to try that. This would be great.
You can copy marker from one file and paste to the other, you have to make sure that you are pasting at the start of your destination file. Copying marker from one file to another in the audio editor has nothing to do with Auto Split.
Are you trying to eventually create a 3-channel file?
You can also try to Normalize your mono and stereo file to -0.5 dB and try if you can get results with other options like silence, cut head etc.
Awesome! I will test this before committing to this workflow, but this sounds very nice. So one split pass to set the markers, another pass to actually split the audio (easy with split presets). Then, I would use a batch processor to remove DC offset, set the levels and add a micro fade at the beginning, because I’m not necessarily splitting at zero crossings. Can I move all markers a bit forward in the file (say 100 samples) to make sure I’m not cutting off too much? That said, I would check where they land to begin with before splitting the file.
I do not think there is an option in Auto Split that creates markers for you. You can try the tab to transient option to create markers or use other auto split features.
Yes, that option is there. It’s one of the last steps of the setup ‘don’t split, just put markers’ or something like that. Very handy and I used that a lot, because it lets you preview where the audio will be split before you actually do it, so no surprises.
That is used when you usually start with a non-Marker Auto Split option… which was not discussed from the beginning. I was also not aware you were speaking in that perspective.
There will be an MRK file near where your new Stereo Audio File is (If not, insert a marker and delete marker and save audio file - you will get a new MRK).
Create a copy of that MRK file and copy the name of your stereo/destination file to the MRK file copy. You can delete that stereo file you initially created for reference later.
This way, you can copy markers from one file to another.
Also, even though your new file will open with markers, they are not saved to the file; to save you can create a random marker on the file, delete that marker, and save.
