Quintessential Player is a fully skinnable audio player that uses a plug-in architecture, allowing it to be as simple or as feature-laden as you like. Go for a minimal installation to preserve system resources, or add a variety of visualizers, library functions, DSP filters, language packs, and other plug-ins to extend the player's capabilities. Quintessential Player has full support for most popular audio formats, including MP3, MP3 Pro, Ogg Vorbis, WAV, and Windows Media. Other convenient features include CD ripping, MP3 encoding, cross-fading, and CDDB integration. Also, Quintessential allows you to listen to streaming audio from broadcasters such as Shoutcast and Icecast.

Version 4.51 adds video support, new plug-in types, new skinning features, improved CD ripping and encoding, simultaneous audio playback while ripping CDs, and an updated interface.
