If You have an Asus Xonar, Auzentech or HT Omega soundcard you will probably need to download the following tool to be able to use the Equalify plugin in Spotify.
These cards all use the same soundchip and use some generic drivers as a base for their brand drivers, and they interfere with how windows is supposed to work.
This tool is provided as a "workaround"
for the issue and will disable the built in GX/EX features of the soundcard. There is also an option to re-enable everything in the tool.
Keep in mind that you use this tool at your own risk. It has been tested
on our side, and there is no apparent side-effects.
After installation you will see an "EQ" button next to your spotify search box. (make sure you play a song and check again before asking for help)
Left click to show/hide the EQ
Right click to toggle the eq on/off.
Save your own presets, or use one of the default presets provided for you. Keep in mind that the default presets are only meant to give you something to start with, you will need to tweak them to make them sound good! (The preamp limiter will automatically turn on when using a default preset)
Automatic pre-amp limiter
Use the Auto PreAmp-Limit to make sure the audio wont distort or clip while using the equalizer. (I reccomend having this enabled)
The "boost" button next to the preset button is for a very low end bass boost ( in the 15hz to around 40hz range). Its meant for people with good speakers/headphones/subwoofers.
Normal speakers or laptop speakers can not play those low frequencies. If you turn it on and can't hear a change, just leave it off.
Send your favourite preset to your friends or put them on your website using the "share eq preset" items in the menu. Using the http link will be easiest, and only people with equaliy version 1.2.0 or above will be able to load the presets.
Ex. (click to load preset in equalify)
