Chop Samples and export in batch

TheAudioDabbler

So I know that several people have been discussing ways to batch export individual slices of audio for use in other apps like Gadget's Bilbao. This seems to have been bought on by the new app Hook, which has a really nice loop slicer and their Hook Grabber is pretty sweet. The only way I have found is using Audacity for batch export options. It seems that even in Ableton Live, there is not a quick and easy way to batch export files. Although I only have the lite version so I cannot speak Sampler or other options that are not included in the lite version.

I put together a quick little video, The audio is louder, although I will try a different mic on the next video to see if I can get a better recording of my voice. Hopefully this helps someone out. Thanks for watching.

BeatTwirl so needs an update ...AB is broken in it

But it's easy to paste an audio file in slice it and export a zip file of the individual slices to another app such as audioshare.

How do you manage to export a zip file please?

Open In for Audioshare seems broken (it does nothing).

@gmslayton With AudioShare, you can use wi-fi file transfer to export/import between your computer and device or if it's MacOS you can use AirDrop too.

Thank you for doing these videos for us. It is surprising that nobody has come out with an editor to create acid type files from samples on iOS.

Audacity for iOS would be the bomb, wouldn't it?

Does Strom not do this?

Is Strom still limited to 10 seconds? I don't have it or I would test it.

If you chop a sample as a loop in IMPC Pro, and AudioCopy the sequence it retains the slices in the wav file. Some apps like hook and others that will be live pretty soon will support that. Which is awesome.

Yeah. Still 10sec.. Lame

Ah thanks. On my iPhone version I don't see the zip icon in the corner. Possibly it only works on an ipad(?)

Ah... And you have to highlight all the slices you want to export.

Well that works nicely on an iPad - thanks.

I'm sensing a 'NDA Slip' here soon haha

Yep. On iPhone sadly BeatTwirl is missing the zip feature.

So you can email a batch of slices. Or save them to the iTunes folder. But nothing else. And unfortunately both email and iTunes folder require you then getting on a computer or saving each file individually anyway - thus defeating the purpose.

But on an iPhone you can at least save individually out to Dropbox.

So a reasonable process if you want to make quick sample kits on the move on your iPhone (for later use in Gadget) is:

• use the hook grabber in Hook to grab a section of a track from Spotify
• Copy and paste into BeatTwirl
• Auto slice with detection (adding reverses etc if you want)
• save out each slice to Dropbox

Pull into Gadget Bilbao from Dropbox at a later date.

Somewhat OT, but I thought I'd share what I came up with today that works in my situation. I own FL Studio on the PC, and though I don't use it much since the iPad came along, it came in handy.

First, I set up a nice long pattern in the iOS app I wanted to sample, playing each drum pad far enough apart that no sounds overlapped, not worrying about keeping the file size small (more on that later). Then I exported the wav file to Dropbox via AudioShare.

On the PC I then loaded the sample into FL Studio's Edison audio editor, normalized it, then chose the fantastic "Trim all noise & slice up" function, which removed all the silent spaces between samples and sliced it up perfectly. I then named the slices, which is really quick for drums with the "quick rename" function. Next I used "Export Regions", resulting in separate wav files for each sample, all neatly organized and named in a Dropbox folder in a few seconds.

Then, over to Bilbao, import > Dropbox folder. Keep the dialog open (use portrait mode ) and tap each pad, then the sample you want on it. Tweak to taste and save. The whole process took about 10 minutes from sample to working preset.

The real nice thing about it is samples aren't any bigger than they need to be. (Hint: Edison converts everything to 32 bit if you don't watch it. If your original samples are at 16 bit, you should force Edison to save at 16 bit to avoid bigger files than you need. Convert to Mono if you don't need stereo as well. *)

[Edit: * Due to a current Gadget bug that produces noise in mono user samples, leave 'em stereo until the bug is fixed.]
[Edit #2 They fixed it! Gadget 2.5.2 landed today and it now plays mono samples correctly. ]

I also saved the full wav file from Edison for use in Abu Dhabi. Even though each sample is a different length, it's still easy enough to adjust the markers

I don't bust the PC out often, but this was one of those times where it made sense.

I think, as in life, "Trim all noise & slice up" is what we're all moslty looking for....
