Hey i've found some github where apparently its possible to use the code to basically decode ableton proprietary file .aif to use them elsewhere.

https://github.com/adamchainz/abledecoder

But i dont understand how i'm supposed to run this.
any ideas ?

 

You need to compile the source code into an executable before you can use this. The "build.sh" contains the necessary commands. If you're on MacOS or Linux, you should be able to compile this after adjusting the paths in "build.sh". On Windows.. I guess your options are WSL or MSYS.

 

Oh, it's true.
Anyways, looking at that .sh file seems you could get to compile it on Visual Studio. Not sure of that though.

 

You're right, it actually compiled with MSVC!

I attached a Windows 10 x64 binary that seems to work for the example file. I don't have any other files to test with.

Use at your own risk (maybe keep it in a sandbox).

Nice. Between the standard C++11 and the only external lib being ssl it seemed "compilable" on VS. But nice that you already did it

 

If I'm not mistaken, the ALP files listed in the Packs section of the Ableton site are tied to your license. I believe this tool could be used to take those same ALPs from the sister site, install them on a cracked copy of Live, then decode all of the audio files from that pack with this tool, then recreate the ALP file as a sanitized version with the decoded audio files. That way, those ALP files could then be used on a legit copy of Ableton if you don't have a license for that ALP, correct? I realize that might be a bit of work is someone is that desperate, but in theory, a legit Ableton user could then install any pack listed on the Ableton site if they went through the hassle of decoding all of the audio files. From what I've experienced, the only thing encrypted in the ALP files is the audio, not the ADG for M4L devices. The only benefit of all this would be for someone who wants to use the audio files outside of Ableton, or for a legit Ableton user who wants to be able to install any pack, even the encrypted ones from Ableton's site.

 

Waw amazing so with the tool it's possible to basically decrypt the aiff ? imma try

 

Can you reup ?

 

Hi xoro, thank you. But how do you use a tool? The link doesn't work https://app.blackhole.run/#adc413544812aMe1koGFYCsqbuz3QJGd1GniQaunbTNo
I only have the attached file abledec.zip
Thanks

 

Attachment is probably all I uploaded to the other link, so you should be good.

Extract the exe to some place, open a command prompt, navigate to that directory, type in:

.\abledec.exe inputfilename outputfilename

 

I don't really understand your link safari or chrome cannot load it.. I managed to compile it on macos but i cannot seem to be able to run it with the command so i want to use your exe to try.. Idk why the link doesnt work

".\abledecoder /path/test.aif /path/output-test.aif" it just doesnt work sadlyyyy

Seems like on mac openssl3 doesnt support bf-cbc (blowfish)

 

Yeah, I vaguely remember having to change something to get OpenSSL to compile with Blowfish-CBC support, or maybe I just had to compile against an older version of OpenSSL.

 

I tested it, but with which alp file does it work?

 

your slash is wrong, it should read "./abledecoder" (linux or macos).
also this is the original project https://github.com/themindlessone/abledecoder
the linked repo is just someone who put a script to compile things

 

Does it matter that its just an edit ?
Fuck i've tried setting it up in windows but windows is so dogshit complicated compared to installing with brew on macos

Nah the slash is right it's the way it's showing that's weird in terminal it's "/"

 

but so maybe can you upload the exe to like https://workupload.com/ ?Idk what's wrong with your link
I cannot change openSSL back to 1.0 it's not working it says
