If you listen to music on your computer (not iPod) then this tool is a must have.
I found this again. It is a plugin that takes the audio from iTunes and turns it into something wonderful, somehow they return the ambience and ‘life’ to an MP3 file. Its simply amazing. I remember using this years ago on WinAMP and it was one of the things that I missed on my MAC.
You can change the settings to increase the 3D, clarity and modify the output according to the speakers including headphones and laptop speakers.
Cost is USD$30, a little bit steep but I will be buying it. Works on OS X and Windows and for a number of different software tools.
Run, and get a demo to prove it to yourself (no affiliate or kickbacks).
