As usual this is an ILLEGAL closed source GUI on top of a PIRATED distribution of GPLv3 FFMPEG.EXE renamed to conv.exe they are also dropping a 701 byte mhsound.dll in the user\[username]\appdata\roaming folder for some obscure probably invalid reason… they should not be dropping files there but using app-specific subfolder and then putting DATA files there not executables except that DLL is NOT an executable it contains seemingly random lowercase alphanumerical strings on seperate lines.
This would be far more useful if it were content aware and split on silences not on fixed timing points which could be mid word or mid musical phrase. This is just using FFMPEG.EXE/conv.exe to do blind splitting it is not fit for sale regardless of the fact it is illegal to distribute in law abiding jurisdictions. They *could* have made it a legal product by building FFMPEG.EXE/conv.exe as LGPLv3 compatible AND gave attribution to the FFMPEG.ORG project and included a copy of the LGPLv3 license but the developers are AMORAL in ignoring the IP rights of those FFMPEG.ORG contributors and wanting to enforce their own IP rights!
