Soundbase was created to fill a gap in the large amount of  free and  commercial players/taggers.
  We do not pretend to have the  ultimate  audio solution, but Soundbase will most likely 
 fit somewhere  into your  playing or tagging experience - it will always give you a  quick
  way of  doing common tasks. 
 
 
 Soundbase uses the Microsoft® DirectShow® architecture. DirectShow   provides
  high-quality capture and playback of multimedia streams. It   supports a wide
  variety of formats, including MPEG Audio Layer-3 (MP3),   OGG Vorbis (OGG),
  Monkey Audio (APE), and FLAC sound files. It   automatically detects and uses
  audio acceleration hardware when   available, but also supports systems
  without acceleration hardware. 
 You might need to read the help section on installing more   sophisticated 
 formats (ape, flac, ogg) to enable playback for those   files. The help section
  provides you with links to free directshow   filters and will give
  you information on how to best install the   different pack.
