Stereo widening / Dolby Mobile / SRS surround sound enhancements

Hi all, my first post here, though I've been using these forums for quite a while. I always wondered why Android lacks behind its competitors in the Audio segment. I searched for hours trying to find a good App that would get me some surround sound on my new LG Optimus One and I was surprised to find none. I heard about the Cyanogen MOD with the DSP manager, but then, this phone is just 3 days old and I don't want to void my warranty rooting it or something.
I know these surround effects I've mentioned are possible on android, since the Galaxy 3 with a 667Mhz processor, 256Mb Ram with its TouchWiz UI is able to provide its users with Virtual 5.1 Surround effects in addition to some basic Reverb effects on its Music Player. More over, I noticed that even a basic Nokia 7210 Supernova with just JAVA in it is able to support stereo widening! Why hasn't android got any stereo widening features or apps (atleast) ?
However, I did find some resources for you developers, which may help you in developing some surround effects like that Dolby's or SRS's

I'm just keeping my fingers crossed as of now, hoping that someone will be able to develop an app or something with these Surround sound enhancements. I guess I'm not alone, there are many, many people waiting for these features on Android like me! Let me know if its possible to implement these surround sound feautres on Android..
Have a gr8 day ^_^

stereo widening
fwiw ....
I was missing srs enhancement on my stock desire z using westone um3x's earbuds ..
I think the sound quality was better on my old windows mobile 6.5 phone using srs wow enhancement.. but the wm6.5 srs enhancer itself was similiar to an equaliser with a lot of user options and NOT the simple on/off toggle "take it or leave it" srs enhancement found in android phones to date.. (see link below)
Nevertheless i thought i'd try android srs so I rooted my phone and flashed virtuous unity 2.37 to test the srs enhancement not available on a stock desire z ..... and whilst it improves the sound the improvement is not significant ....
I have since gone back to stock gingerbread (NO android srs enhancement) and purchased music playerpro from the market; its audio effects use the new audio enhancements built into gingerbread including stereo widening.... (the "virtualiser") ... and imo are superior to the dsp power pack... and now i feel i'm almost back to where i was on the music front using wm6.5 and srs wow enhancement....

PS - I'd gladly pay srslabs for something like the old srs wow application working on android .... also i'm not affiliated to playerpro in any way ....

Viper4Android FX would be my suggestion...found here: http://forum.xda-developers.com/showthread.php?t=2191223
I used stock BoomSound to start, then tried the Harman/Kardon mod. Boomsound really washed out the mids, and Harman/Kardon default was really tinny sounding in the highs, to me. I flashed Viper in TWRP, and it's been working great for months. You have a ton of options to tweak the sound however you want, but I'm running mostly stock with just a slight boost to bass. Mostly listen to music in my car, so I probably don't get the full details in the music, but the balance is great...way better than Boomsound, to my ears.
Check out this Anandtech writeup that includes Boomsound analysis: http://www.anandtech.com/show/8078/smartphone-audio-testing-htc-one-m8-and-samsung-galaxy-s5/2
Can't speak to the quality of Project Era or Sound Explosion, so I don't have any comparison opinions. Hope this helps!

I remember "mic fix" and "stereo mod".

arise and root

There are a lot out there..!
Actually there are a lot out there but it depends on you what is required to you for example i wanted better music so i installed viper4Android so for your question there are a lot out there but you need to install only what you need. so here goes my favourite list.
CrossBreeder Lite Edition
CrossBreeder is a set of mods that are used to modify system performance as well as conserve battery life. While the original project required proper /system access, it has now been ported to work with Magisk, and it works exceptionally well. You can use it to reduce the lag, increase your entropy levels, get more juice out of your device and speed up your mobile.
Audio Modification Library
There are a number of sound mods available for rooted Android devices, like the aforementioned Viper4Android, AM3D Zirene and Dolby Atmos . Based upon your liking, you may want to one of them. But what if you like different features of different mods, but installing both mods at the same time would result in a system failure for you? Well, Audio Modification Library is a Magisk module that overcomes Magisk’s limitation of installing multiple audio mods, and does not cause any compatibility issues.
Viper4Android or AM3D Zirene
Viper4Android is by far one of the most feature-rich and advanced music mod out there for Android. It lets you alter almost each and every aspect of your device’s audio capabilities, thus giving you full control. It lets you customize the audio performance of your device’s speaker, Bluetooth speaker, headset or even a dock. The app not only increases the volume of the audio on your device but also improves bass & clarity, thanks to the cool ViPER Clarity and XHiFi technology.
Even though the interface is fairly easy to use, one might get confused with so many choices at their disposal. If so, you could opt with the AM3D sound mod by Zirene, which offers a simple and minimalistic interface, allowing easy tweaking around with the audio profiles for your system.
Dolby Atmos
Lenovo had introduced Dolby’s Atmos Sound technology to their devices a couple of years ago, something that was widely appreciated. The Dolby Atmos Magisk mod brigs the Dolby Atmos audio enhancements to any Android smartphone. The mod offers simple yet efficient sound modifications to the overall audio quality of one’s device. This app, which was earlier exclusive to Lenovo’s ROMs, has now been ported to Magisk, so that it can work systemlessly. You can customize the audio quality of music, movies, games, voice, etc. There are a lot of options here and if you are an audiophile, you will definitely appreciate the features on offer.
Android Mic Fix
Many a times, after flashing a new ROM or firmware, you may experience a loss in the mic quality of your device. The reason behind this is that most of times your build.prop file is tampered with by the developers which causes the aforementioned issue. The Android Mic Fix, as the name suggests, aims to fix this problem with the help of the “resetprop” tool to modify your build.prop file.
Hit thanks if I helped you.

Stock Q no longer provides Audio Enhancer&Equalizer

Hi,
I send Feedback about it to Xiaomi and they said this:
"Dear user,
I am the Xiaomi user feedback group. The feedback about the Equalizer. Due to the adjustment of Xiaomi business, the Q version no longer provides this function, which is inconvenient for you."
So dont expect it on the future versions.

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.

Why doesn't YouTube have Surround Sound in 2021?

Hello there, guys!
The question is not a new one. It has already been asked a couple times over the years. For some strange reason though, nothing changed.
Surround Sound is glorious. You don't even need an expensive setup, nowadays even normal headphones or sound bars can utilize algorithms or separate drivers or speakers that can create a wonderful experience - even "just" from your everyday phone. No matter if it's 5.1, 7.1, or if it's labeled Dolby Atmos, or some other fancy 360 algorithm, just like Sony created with their newer in-ear & over-ear models ("360 Reality Audio").
It's been bothering me for years. Especially if you think about video game footage - or just in general: content - that has been created and could be improved so much by a more immersive sound experience.
Even phones nowadays can utilize spatial algorithms. Just think about phones that can be improved with Dolby Atmos. Samsung has already enabled this. Yeah, those tiny little speakers. And yes, Thomas - around the corner in his sound bunker - with his $9,000 dedicated & custom-made Dolby atmos home speaker setup will at this point call me a fool. Even though he will likely benefit a lot by surround sound with YouTube.
It's almost undeniable that surround sound is great. Everyone that has ever played a game or watched a movie with a device that can enable a sound experience will be quite likely to agree here.
So the question remains, why doesn't Google give a sh*t?
Back in the days, people argued with the amount of data required. Nowadays, where streaming services prove with all their fancy algorithms that even a tiny 20 Mbit connection can sustain a 4K Dolby Atmos stream, that's just out of the question. Especially since YouTube can buffer and you don't even need a perfect connection, worst case you just need a little patience.
So I would like to hear your opinion on the topic. Do you give a sh*t? And in case you don't, please be honest here, have you ever had the chance to experience surround sound?
It is known that Google has dived into this topic a little bit. They have enabled surround sound with Stadia and with YouTube TV. So the next logical step should be YouTube. But nobody talks about it. And that's a shame.
I want you guys to talk about it. I want us to have a conversation. I want Google to notice.
And then to give us surround sound. I mean 120 Hertz would be a nice addition, or Dolby Vision or something like that, but you take what you can get, right?
Cheers!
