It seemed it worked. In addition I has OGG and AAC files support.
Roughly 4-5 times slower that other audio matcher tools. Uses only one CPU core.
Despite that I didn't find many duplicates removal tools with acoustical audio matcher, I don't recommend this tool, there are out better tools on the martket available. If you are a MAC user I would recommend Phelix (yes there is a Windows version too but the path in the Search Results List is incorrectly formated). It seemed there is only one option for Windows users - dupeGuru Music Edition.
