    Registered just to rate this. Been using Equalizer APO for a long time now, but Peace is amazing. If you listen to music on windows and don't have a soundcard (or maybe even if you do?) definitely use this and APO!

    Top notch! Using Peace GUI with Equalizer APO (32 bit). Exactly what I was looking for. Thumbs up and thanks to the developer of both these excellent projects!

    Compared to the recommended option for using Equalizer APO (Room EQ Wizard), this method is a lot more intuitive to use and lightweight. While the UI may seem a little dated and hard to understand at first, the entirety of the functions of the two screens of this app (!) becomes clear after only a few minutes of tinkering around This app does everything you'd expect it to, which I won't elaborate here (read the app description) Overall an awesome app

    Asus Xonar Essence One = piece of crap [SOLVED] ! :o) When I first got the Essence One external headphone amp I thought it sounded like a piece of crap because you could not use the Asus Audio Center audio software like the quality equalizer. I had used the Asus Xonar Essence STX internal soundcard for few years before, always with Asus Audio Center + Sennheiser HD600 headphones and it is best sound I ever heard on my computer. I tried many windows Equalizers softwares as I could to try to overcome the problem but gave up because none sounded good enough. I thought I may have to throw the Essence One off a high bridge onto concrete in disgust. But 6+ months later Peace, GUI for Equalizer APO has saved its life and my $. This software make Equalizer APO more user friendly. It makes excellent sound, the same if not better than the high quality Asus equalizer.
