Do not worry I do not update beta versions tester on my utility..
You run too much with your masks...
, you have added the mask for the recompression data in MP3, not hear any difference in the optimization of compression threshold.
Tests executed on a data folder mp3 approximately 234MB
Masked method used for Test: "precomp+msc+srep64+delta+exe2+lz77/$jpgsolid=jpg+zstd/$mp3solid=mp3+zstd/$void=srep64+zstd/$text=nz"
Your update: v 2.2..
M_S_Kompressor with optimized profile based multi mask By Panker..
Personally, I may be wrong, I not have so much experience in data compression, but exceed on a number of algorithms containing in the method multi-maschera, involves a loss of a compression stream, increasing the compression time, and decreasing the compression threshold.
