[Xiaomi Mi A2 Lite Guides, News, & Discussion] TeoXSD:
Solution for missing sound setup.

Not that the stock equalizer that came from Android Pie was any good. We just need people to try and revive the old DogsBark team (Noozxoide Laboratories) and make rootless DSP. I have nothing against Viper, don't get me wrong, on my other device I use Viper Audio, root and all that stuff... but sometimes you just need to stick to the old user/non-dev ways. I am sure it's possible, the problem is the financing and the will to do it. For me, the app developed by them and last updated in 2013 worked like a charm on many devices... except this one, since november update... That's when the problems started to appear.

Since then, I've been looking not just for an equalizer, but a self contained DSP pack that would work better and guess what, nothing's there... nothing except apps with built in function (which by definition are not system wide) and crappy adware.

As for the "Xiaomi business" this really shows me that Xiaomi really gave up on the development of this device, and ALL stock Xiaomi apps will be gone, replaced by Qualcomm's apps... and I don't ever recall seeing any DSP coming directly from Qualcomm.

----------Later addon----------

While the PRO version of Noozxoide EIZO-Rewire PRO has the problems mentioned it seems that the second software Noozxoide EIZO-Rewire Elemental which works even better is still compatible and working just fine on Android 10. Right now it's in testing and benchmarking... which is not an easy job to do, but as long as I love quality music I will do it and post results/download links for it.

-----Download Software-----

Download the Noozxoide EIZO-Rewire Elemental from HERE.

-----Testing abstract-----

For the following tests, were done using only hi-res audio (FLAC/ALAC 96khz 3mbps) files and 320kbps mp3 files so results may vary compared to what I tested here. Remember that streaming services use low bitrate/extremely compressed content.

---Test Speakers---

Internal audio speakers has a good response, bass is there audible, resolution is good, in this case I cannot post any reference to advanced graphs since they are irrelevant in this case.

The best settings (for me) are posted in the first screenshot here. While this is my recommendation, the software doesn't go overboard and keeps the audio quality in control. While testing all the test tracks which varies from Rock/Metal to Acoustic to a more aggressive dubstep there were absolutely NO cracks and pops in audio output from the speaker (which is a result of poor equalization/frequencies outside the speaker range).

---Test Line-Out/Amplified output---

Headphones (because of my current limitations of testing - a conclusive test would be source file vs. processed audio output and multiple headphone test - in ear, open back, ported, etc) were only tested with 3.5mm jack Apple EarPods which are well known to have the best consumer grade frequency response I found that the 2nd attached screenshot works best (for me). While some FLAC files with really deep bass (about 6-10Hz) totally overrun them (and not the Qualcomm audio processor) I would say that this DSP (VSP) works just fine on our devices.

I don't know if I should leave a placeholder here for the advanced, audiophile grade, passive amplified headphones.

---Test Wireless Audio---

Bluetooth and wireless media. Works just as expected. Test were done only with a Nokia BH-503 headset (couldn't test on the car, and neither did I want to spend time going to the car and test it on the BMW Pro-Logic system) but on those headset it made them literally vibrate on the ears, extremely good quality sound, deep bass, crystal clear trebbles and warm mid-tones. Again, I didn't manage to get a single crackle or pop on the speaker drivers which means the equalization done by this engine is sensible and perfectly limited/compressed. The settings I used are posted in the third screenshot.

-----Conclusion-----

The solution posted here works fine, while extensive testing the app still shows that is consumed 0% battery, so the battery drain is minimal.

The application works perfectly after reboot and closing from the recents screen, there were no modifications done/or excluded from the battery optimization screen.

This application is not a booster, this application is a DIGITAL SOUND PROCESSOR controlling the Qualcomm core (was built for this back in the day) and upscaling the audio resolution.

-----Q/A-----

Q: Does this app require any tampering with the system?

A: No, this app is installed as a normal app from the link provided (Play store link)

Q: Does this app work as a system wide equalizer and integrates in other apps?

A: Yes, yes it does, and from my testing it works with all media players (the equalizer option opens up the app), Youtube, Games, etc.

Q: Does this app consume system resources while processing?

A: Yes and no. Of course you need system resources for processing but they aren't that intensive at least for MP3 processing but for FLAC/ALAC processing things get a little more frisky as shown in the 4th screenshot attached.

Q: How's the battery drain overall with FLAC and MP3 playback?

A: Depending on the method of listening the drainage is different, but even on Bluetooth the consumption didn't affect my battery overall.

Q: Does this enable AptX?

A: No. This has nothing to do with that. But while AptX and SBC are not that different in base audio quality, this pushes the codec to 328kbps and upscales the audio to a resolution of 48khz which is ideed great for maxed out mp3 quality over Bluetooth, which again is based on the source files.
