    I've looked on and off for several years for a suitable Windows equalizer, and this is the only one that not only works great, but actually lets me use my surround sound speaker system to its fullest extent. Being able to upmix to 5.1 surround and have it work, where the Windows enhancement version doesn't, blew me away. When I hit upon it, it made me stop everything else I was working on and write this review. The effects panel is incredible! Just looking through the rest of its capabilities is mind numbing. Anyone looking for a Windows equalizer needs to have a look at it - nothing I've found even comes close! Hopefully support and advancement for it continues, because I've found many Sourceforge projects seem to come to a halt. It would be a shame to see that happen to this great project!

    This is absolutely the best EQ for Windows, should be stock by now.
