This could be done with a tool which overrides the internal wav file loader.
The tool would load the wave file with the built in load_from(file) function then re-read the file into memory and parse out the required data chunks.
I could probably do this if required. Probably as a stand alone tool for testing but it could be merged into the Additional File Format Import tool once stable.
I’ll have a look, but it won’t be in the immediate future due to working on Cells!.
Foxbunny: please send me some example sliced files for testing and development.
