About this app

Neutralizer is an equalizer made for sound restoration in mind, contrary to many other products that offer ready made profiles for sound distortion. Everybody is different and everybody’s hearing is different. You have to test your hearing on devices that take active part in sound reproduction in order to be sure that any adjustments you make will work for you. We offer simple to use interface that needs very little explanations. It is self explanatory. And it is elegant.

Why Neutralizer?

If you would like to improve your listening experience on a mobile device, you would mostly come into conclusion that you need a better hardware. Although in most situations it might be true you don’t always know why.
This is because of so many parameters you have to take into account like: the digital to analog conversion, the signal frequency range, the amplification path, the speakers (or headphones) frequency response, the psychoacoustics and so on. You can measure each of the parameters, but to measure them all you only have one device—your ears.

One way to improve your hearing ability is to use sound enhancers like equalizers. Most of them distort sound quality but if you use it wisely, you can minimize the deficiencies of your acoustic tract. The key word here is “wisely”.
In order to do it wisely you have to make some tests to discover the problem.
And that’s what Neutralizer does. It tests your hearing ability in key frequency ranges and adapts the system equalizer to take it into account. As simple as that.

Current limitations: the sad fact is that Neutralizer will not work for everybody. There are mobile devices not compatible with our solution that don’t allow third party apps to control system equalizer. We are working towards a solution to satisfy everybody, but for the time being your mileage may vary. It is, what it is. Please don’t give us bad rating because of this. We told you so.

Works with most apps. Not with YouTube, as far as I can tell. Detects my car's Bluetooth connection when I add a profile, but doesn't affect the sound. Once in a long while, it seems to stop affecting anything, but that might be because of any other equaliser app. Got premium, but auto-profile chooses…almost randomly. I tune for "softest I can hear" at each frequency", then raise all but one of them until the sample tones seem about the same loudness (aiming for perceptually flat response).

Update: once you tune up your device using this app, you have to leave it running in the background to allow it to equalizer your audio output to your sound device, whether it be earbuds, a headset or speakers. It works well with Bluetooth or phone jack output. I haven't tried it with Wi-Fi Direct yet. Also, since this app has no presents for different styles of music or environments, you have to create setup for each situation. I'm not sure how you would go about creating set ups for different styles of music as this app is designed to let you fine tune your sound output to your ears for the best audio quality for your environments and equipment. This app is not an equalizer in the normal terms that most think about. Instead it allows you to fine tune your device to the speaker or headphone/earphones you are using. It does this much like you would when going to get a hearing test so that you can get a hearing aid adapted to your specific hearing. Only in this case you are fine tuning the frequencies in the audio output to you sound producing device and to you specific hearing. Being an Electronics Engineering Technician with over 40 years experience with both audio, video, industrial & medical electronics working both with analog and digital devices, I find this app the most impressive app for smartphones & tablets I've seen and experienced to date. Clearly the developer has similar knowledge & experience.

Holy f------g hell. I was testing Neutralizer out and things seemed fine until I hit the edit profile pencil while audio was playing. It suddenly cranked the audio up to an insane level--it was actually quite painful. It was far, far louder than I've ever gotten audio from my phone before. Be careful! This was really very painful. On a Pixel XL, Android 9, Jet Audio Plus, Sennheiser Momentum M2. Easy to reproduce - - tap the pencil, audio is briefly pegged to a crazy level. I like listening to loud music, but this was way over the top.
