Neutron is an advanced music player with the bare-metal 32/64-bit audio engine which delivers the best possible Hi-Fi grade quality of sound. It offers high-resolution audio playback without frequency resampling and bits truncation if internal/external DAC supports it. It supports all major platforms - Google's Android, Apple's iOS, Microsoft's Windows 10 (UWP).

Thanks to input/output network capabilities Neutron is the only application in the market capable of sending audio to the network renderers (UPnP/DLNA, Chromecast) with all DSP effects applied including true gapless playback. Neutron can source music files from device or network sources such as SMB/CIFS, UPnP/DLNA, FTP, WebDAV and send audio either to headphones, or directly to USB DAC or to UPnP/DLNA or Chromecast renderer without a format limitation!

Its reliable, platform independent, native core provides consistent behavior on all devices. Carefully developed DSP effects such as Parametric or Graphic EQ, Compressor, Surround Sound, Crossfeeder, Crossfader, Tempo, Pitch and others, help to tune audio to a desired result.

It features the sophisticated UI with advanced options and controls for music playback. It is not an easy or another 'pop' music player, it is developed for audiophiles and those who really in love with music. Get used to Neutron and have full control over your media library and sound!
