Best App To Chop Up Sample Chains
I’ve acquired a number of sample chains containing 64 samples. I’d like to chop those into 4 x 16 sample chains for use in apps with 16 pads/slots.
What iOS apps do you know of that allow for easy importing, chopping and saving of one chain into four (or many)?

Digichain is a free web app and is excellent for this kind of thing:

Great site. Thank you.
I think Wavebox is the best tool on iOS for sample chopping, especially when dealing with larger files with many samples in one file.
Where’s the option to split the OG sample into 4 equal parts, am I missing something?
💯 Amazing web app, excellent UI.
While you can’t do that there is an auto slicer under more->selection that you can adjust the threshold on which is great for one shots. You can also play through the file and mark spots and then create smaller files from all of the marks. It brings up all of the smaller files you’ve created for further editing or export. Wasn’t super intuitive at first but play around a bit and it’s worth it for sure.
So if you wanted to split into 4 parts you just throw your marks down and go to more->edit->split regions.
My preferred tools for this would be Koala, or the Flexi Sampler in Drambo.
Koala has loads of slice options (equal parts / by transient / manual). It will split your audio onto individual pads which you can render or do whatever with.
Flexi Sampler is pretty much the same but maybe not as immediate.
Lastly, I really like the app Meow for more general audio editing. It’s very pleasant to use!
Start out with Digichain. It’s a batch processing monster. Listen to @tahiche
When I had a hardware sampler I processed dozens of folders of samples in minutes.
I was trying Digichain out and never got it to do anything for me. I made a test file of 5 notes separated by short silence and when I pushed the button it just showed me a spinning disc. I came back to it half hour later, still spinning; gave up. I probably was doing something wrong.
So I went to Wavebox as long as I had it, and found that to work much more easily for me. So no need to coach me, I'll stick with that. Just thought I'd mention it.
But I'd be curious to hear if anyone else has success and how quickly it worked for you.
Harry Gohs’s (Virsyn )* ReSlice gives auto slice and positional editing along with bulk and individual wav export. The only caveat is that it doesn’t recognise Tascam broadcast wav standard. VirSyn is aware and will address the problem.
+1 for reslice
Wavebox
Best audio editor to prepare samples for koala, digitakt, sp404, flexi sampler… and the list goes on…
Its amazing and i love how it bakes in your audio unit effects , a true gem 💎
In digichain there are a few different ways to do this, you can load in the samples, then for each chain, use the 'slice editor' icon per row to bring up the slice panel, from there if the sample has slice data embedded into it, you can slice out the chain to the individual samples, then build the new chains of the desired length from the samples.
If the samples being imported are chains that are already evenly spaced, from the slice editor, click the 4 button then click the 'slice to samples' button to get 4 new samples from the one chain.
What browser, and OS did you get this issue on? (and also, how long ago? as I do frequently update and bug fix). Thanks!
Absolutely on this, digichain does work on iOS, but its better suited to a larger screen like iPadOS (works great split screen with the files app for drag and dropping) and best on desktop computers, especially if processing lots of nested folders/zip files.
I was on Firefox on my (old) Mac. I don't want to put people off from using it. It looks like it has a lot of capabilities. Like I said, I probably didn't do it correctly; just didn't have the patience to persist with it.
Thanks for the details, most likely the version of Firefox was too old to support the audio processing as it does rely on some fairly recent browser features.
So best to be running the latest version available, with the tested minimum versions being:
Other browsers have no verified support.
Recommended minimum OS:
Recommended minimum hardware:
Apple A9
4Gb RAM
I’m always happy to help if anyone runs into problems, or has bug reports/feature requests for me.
I use DigiChain on my iPad. Its batch-processing capabilities are second to none. Somebody sent me a bunch of stems as MP3’s. It took less than a minute to convert them to normalized wav files. Chopping capabilities work similarly. Plus the dev is super responsive. @brian3kb
