No, the so-called modification is the modification after converting it to jpg. There are not many software that can recognize and operate the raw format. They are basically the official post-production software of SLR, such as Nikon's nx, and others. They are Adobe's Lightroom and PS (PS is modified by an external import plug-in). Of course, the best one to use is Lightroom.
The reason why it cannot be used is not a technical issue, but that there is patent protection in the MP3 format.
