hey up-

best 2017 method to batch convert wav to apple loops? i.e. an enormous folder of 122bpm loops in wav format; best way to convert them to apple loops?

thanks in advance




*edit: have not moved to high sierra yet

Myriad, or it's predecessor Sample Manager, which' interface I prefer over Myriad..

 

SOLID. thanks man

 

Does Myriad also convert Apple Loops (wav and aiff) into normal wav files? I know you can do this in Logic - from wav to aiff to wav - but it's a bit time consuming and when the Apple Loops are already in aiff it seems a bit problematic. Or there must be a workaround I'm still not aware off.

 

You can use Amadeus pro to batch convert from caf to wave. Just did it with the entire apple loops library. But don't do all at once - it 'll choke ... 1 or maybe 2 folders at a time !

With the new version of Logic there's no need to convert files anymore.

 

I'm on osx and I wonder what is the advantage to use apple loops, can someone explain me that?

 

But I wasn't interested in caf vs wav
Some additional info: I hardly use loops but drum loops might have sounds included that I like, the 'problem' with apple loops is that you first need to convert them before you can use a wav editor to cut the parts you want (and save them as one shots).

 

Some people call "Apple Loops" just riff audio file with the extension AIF(F)
For me a basic "Apple Loop" is an aif/aiff/caf riff data containg musical metadata like tempo, bars/beats, signature, musical key, slices/regions and keywords
A more specialized Apple Loop does even contain stuff of matter for apple sequencers, like a preset for an instrument track plus midi data - so when i drop my loop onto an instrument track it will load the midi, the "vsti" and insert effects - dropped on an audio track it will load the wave file (riff) data (loop) - exciting stuff!

 

If your editor doesnt support aiff you should switch to something serious, let me guess you edit your files on your android smartphone even my amiga was able to handle aiff - on osx myriad is my goto tool for batch processing but its a bit slow and very picky with input, it crashes too often

Wrong guess I didn't say anything about file support, you just can't edit apple loops and save them as a normal audio file without leaving metadata behind and using them as one shots or whatever in your DAW. That's why a conversion is necessary. I'm using Sound Forge, which is as serious as it gets. Here's my 'smart' phone btw ..
.. so no editing.

 

that's what you said ...

... and it is not true. So I understand your editor can't handle aiff files If you need to convert them first ...

give me a file that troubles you, i also have soundforge and love it and it will edit apple loops as long its not an coreaudio .*caf container. As

From what i understood you'd like to:
- Strip all metadata that defines the loop ...
- Cut out a chunk and use it as a one-shot sound ... e.g. a kick drum
- Save it as microsoft PCM wav


Or do you mean AIFC files by chance? AIFC is a compressed version of an AIFF and its support its not that widely spread ... iTunes on windows can convert them to wav or aiff (or at least it did it 8 years back)

 

Alright, I had to add the info from my last post to the additional part to make it completely understandable. But responding with switching to something serious and editing on a phone felt a bit like criticizing in a mocking and dubious manner. That said, yes your summary is right.

However, the point is not a file that troubles me but finding a faster way to convert a whole folder or library at once without following the time consuming way I described earlier. Which is still necessary because editing an apple loop won't remove the metadata. It needs to be a normal wav or aiff file first (that's what I meant).

The loops I'm talking about are also in wav or aiff. Logic has the rule that you must convert wav (apple loop) to aiff (normal loop) instead of wav (apple loop) to wav (normal loop). Which isn't a problem. But if the apple loops are already aiff you can only do it one at a time. So it would be helpful if there's a converting tool available that has an easier workaround. Like dBpoweramp for example, which I use for wav vs mp3.

By the way .. "With the new version of Logic there's no need to convert files anymore." .. of course there is. Because I need an editor - SF in my case - with zero sample accuracy zoom. But that's another story (or was) > https://audiosex.pro/threads/audio-editor-for-mac-with-zero-sample-accuracy-zoom.29888/

 

fastest way to strip all meta from wave i can think of is sox, a commandline tool - it will generate a pure wave file with absolutely no meta left. There are also lots of crappy batch processors that dont give a fuck about meta at all - but dont ask for names as i trashed them all as i saw my hard work of meta work vanishing with the use of it.

BUT myriad can clear meta from waves "clear properties" found under "properties" category
If you want to extract slices or beats myriad can do - see "extract" category

Myriad is the first serious batch tool on osx, you can trash the rest - but it should be more stable and capable of handling 1.000.000.000 files without hickups :D - The problem with myriad is: 1. It scans all files upfront and crashes when something goes wrong - so when i throw 10k files on it and the 9999th file crashes the app because of a bad bit set, i get mad as i waited all the time for nothing as it wont tell you what the problem was, so there comes manual troubleshooting ... So Myriad is feature wise the best but sucks performance wise at the same time. So its a batch tool for smaller batches of perfect waves

If you prefer sox - you might use a something like this in a terminal

find /The/Folder/With/Waves \( -iname "*.aif" -o -iname "*.aiff" -o -iname "*.wav" \) | while read wave ; do

sox "${wave}" "${wave%.*}-new.${wave##*.}"​

done

Don't forget "Convrt", the little batch utility from the Sound Forge Pro 2 package. It's the only one I have seen that is remotely coming close to sox in terms of speed, and it's especially handy for converting to compressed formats because it uses all CPU cores simultaneously.
I'm also a "pro" sox user, but most forum members wouldn't accept fiddling with the command line as long as there's a GUI alternative.

For me, the main reason to keep Apple Loops is the slices.

Maybe anyone can answer this:
Does Myriad translate them to Acid WAV slices? And can it re-apply slice information to existing REX/RX2 files?

 

Hmz it seems that clear properties didn't work because Logic still sees it as an apple loop with follow tempo option. Maybe there's another action from the list that does the trick ..
About sox, I must agree with the above reply, messing with the terminal wouldn't be my first choice.
I still have Convrt btw but it seems that it's not working properly (but I also need to get rid of older apps and be up2date when upgrading to the next OS X).

Maybe it's not a big deal to keep converting inside Logic after all, it's not that I need it every day or week. Only when buying new sample packs (especially for the drum hits) and finding some useful sounds in the included apple loops.

 

Meta doesn't stick when handling AppleLoops - a real bummer as its my second choice converter. Destroyed me tons of Properly tagged AL by just altering the bitrate, too bad I haven't noticed in time :-(

Please send me the file of interest by message - I have to check. Just an idea: Myriad: covert AL -> WAV (options: clear properties)?

 

Thanks for warning us, didn't know that!
