What is even more interesting is an interface that Foobar2000 uses. By being present on the market from the December of 2002, this great audio app that was created by Peter Pawlowski (former employee of Nullsoft, creators of worldwide known audio player Winamp) managed to steadily grow over the years and adopt tools and features that will make any music lover happy. Foobar2000 is freeware and an advanced powerful audio player for the Windows operating systems, with a great mix of both basic features that include full Unicode support, ReplayGain support and native support for several popular audio formats, and advanced services that will be attractive to more seasoned users and music professionals who are requiring little more than just simple audio playback.
