After installing, all you really need to do is play some audio and FxSound will boost your sound automatically. You don’t even need to turn it on! Although I recommend giving this a shot to hear the difference for yourself.
If you need to dial in your settings more, try adjusting the Effects.
Or change your audios levels or target frequency with the equalizer (EQ).
Once you’ve found that sweet spot, save your settings as a custom preset.
If you aren’t hearing your advanced audio right away, make sure to check that you’ve got DFX Speakers selected as your playback device in Windows.
From there you’ll be able to adjust your playback device in FxSound to hear your boosted signal.
