Realizer Plus for Mac

From Arboretum Systems:

MP3 files just don't sound as good as the original CD-quality recordings. The bass loses punch. High end lacks crispness and definition. The stereo spread collapses. Moreover, people are often listening on inexpensive, low-quality speakers. Unlike conventional equalizers and bass/treble controls, Realizer actually adds missing frequencies and synthesizes new harmonics to recreate the sizzling realism of the original recording. Realizer combines proprietary Bass Maximizer, Harmonic Exciter and Stereo Enhancement algorithms - the same processes found in Arboretum's professional Hyperprism products - in a simple-to-use interface designed for personal music enjoyment. Realizer Plus for Soundjam adds five new "effects" on top of the ones included in Realizer. Realizer Plus for Soundjam is completely user-configurable and includes a number of factory settings designed to bring the most out of each musical style.
