Hello Florian.

A special variable %\_md5audio% could be used successfully while exporting data. It works instantly for FLAC and fast enough for MP3.

But instead of exporting I want to write audio hash to some special tag of MP3's. Can we have %\_md5audio% working in Actions also? Or a tool function writing value of %\_md5audio% to a special tag?

UPD. As I just understood %\_md5audio% works for both FLAC and MP3 while exporting. Within the actions the FLAC is only supported. My idea is to support MP3 there too.
