Neutron is a professional music player for audiophiles with a reliable, 32/64-bit, platform and OS independent audio rendering engine which delivers the best possible Hi-Fi grade quality of sound on your Android device.
Neutron features a unique implementation of DSP effects which you won't find anywhere else.
It can read music files from a device local storage (including SD) or network sources (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 and with all DSP effects applied - do not miss this unique functionality!
