AIMP
AIMP (Artem Izmaylov Media Player) is a freeware audio player for Windows and Android, originally developed by Russian developer Artem Izmaylov. The first version of AIMP, dubbed "AIMP Classic", was released on August 8, 2006. AIMP was initially based on the BASS audio library. Version 3 added a new audio engine and full support for ReplayGain, and revamped the music library interface transparency effects.
Official site news entry denies the connection between AIMP development team and the donations being collected by aimp2.us website, and calls the latter a fake.
