Binary storage Delta

I am looking for a binary delta storage solution for large binary version files (digital audio file files)

When working with DAW files, most of the changes, especially towards the end of the mix, are very small compared to the huge amount of data used to store raw data (waves).

It would be great to have a version control system for our DAW files, which would allow us to revert to older versions.

The system will save the difference between the binary files (diff) of each version. This will give us a list of instructions for moving from the current version to the previous version without saving the complete file for each individual version.

Are there any existing version control systems? I read that SVN uses binary difference to save space in the repo ... But I also read that it actually doesn’t only do text files for binary files ... Not sure. Any ideas?

My plan of action at the moment is to continue research in pre-interacting tools, and if there are none, it will become comfortable to read binary data from c / C ++ and create the tool myself.
