Sonus Dept. is a small company focusing on sound design and research, providing you with high quality sound libraries, sample packs and custom sound design works.
Behind it, there is Valerio Orlandini, musician, sound designer and software engineer from Italy.
Some stuff is given for free (and all the software is / will be released under open source licenses), other for very competitive prices.
Sonus Dept. is available for custom sound design projects, too.
