NEW FEATURE: OriSound - long-awaited feature that allows to record audio exclusively from selected game or application! Don't waste money on additional PC or specialized headphones! Now you can select your favorite voice chat application (like Discord) and record it into separate audio track that will not be mixed with main audio track! Additionally the sound you record will never be modified by sound card post-processing so you always get the original volume, pitch and tone. It will also not get disturbed by random system "blips" comming from popup windows etc.
