Not bad... Stumbled across this and noticed it is updated from version included in Nexus 7. Disabled that and installed this. EQ response is much better and interface is improved. Add more bands(could use say a 500 hz slider in between for small speakers) and support audio formats like AAC+ for 5 stars. For those who say it don't work, RTFM! It is called and used by other apps as it says. It is not standalone, rather a plugin.
Works on spotfy Search for equalizer under Spotfy settings (or whichever google's standard adherent player). The app is great, but google's android equalizer is not that much (blame google). Eq will slightly lower your total volume. The eq settings are more noticeable on headphones and it will really improve sound. Using eq with external BT amplified speakers works well but If P2 cable is used volume will get too limited, specially on low power speakers. Also, the difference In quality will be less noticeble. Great anyway
DOES NOT WORK ON HTC ONE M8 The problem I found after I downloaded this app is the fact that the HTC One M8 does not hav the option for an equalizer. The Harman kardon system has its own equalizer built in and as far as I can tell, it's inaccessible.
How I love this app! Works so smoothly, perfectly on my android music players on cellphone & tablet. Dramatic increase in sound volume, clarity, bass & surround effects. Constantly working with no distorted or scratchy sounds. So light & easy on memory & battery use. What a way to enjoy music!
Best app It is for music lovers to tweak music.I had its predecessor "Dolby digital" but it stopped working on lollipop. Now downloaded, works perfectly, pretty simple and integrates with default equalizer. Thank you so much for making this app.
Functions perfectly. Needs a facelift. Call me a snob but this app needs a facelift. Loved it on my Nexus when it followed the ICS design guidelines but on its own it's hard to look at. Works great though but with Lolipop here there's no reason to look so atrocious.
