Hello there, is there any diference between audio qualify from headphones out stock vs cm?
This is the big question for me since I own a pair of NuForce NE-700M and plan to upgrade to Yamaha EPH-100, and roughly 90% of my smartphone usage is just listening to music. GSMArena shows stock playing with enjoyably low THD (I know some of you aren't too fond of their review process, though).

Stock has workarounds for the cheap buds that come with the Oppo - but Dirac HD is unnecessary for decent headphones and in fact ruins the audio quality if used with good headphones. So if you use decent wired headphones you should not hear much difference if any. Some A2DP (stereo Bluetooth) devices have issues with 4.2 due to the new Bluetooth stack, however I can't reproduce this with any of my A2DP headsets.
I listen often music at home and sometimes I have to use my headphones (Fidelio)
Tested CM on Oppo which I preferred used on my HTC Sensation, but on the Oppo I am especially due to the sound quality back to Stock because in my opinion is the overall sound much better, especialy with MP3 320 kbps which I normally use. Only issue is that Stock in combination with the Faux Kernel causes sometimes a few problems.. However I have clearly to recommend the Stock for Music Lovers.. but try it - because ears and sound preferences are different
And by the way DiracHD is not only to improve cheap earphones, don't forget you have not the power of a High-End Amplifier in your pocket therfore is such a sound improvement a good way to have a much better sound on good headphones as well....

No, DiracHD only works with cheap headphones - more specifically, *only with the cheap headphones included with the device* - it is an EQ preset that offsets the deficiencies of the OEM earbuds. Use it with anything that doesn't have the exact same frequency response and you correct for problems that aren't there - effectively creating new problems that didn't exist.
Effectively it's an audio form of RF predistortion - http://en.wikipedia.org/wiki/Predistortion - Applying predistortion to anything with distortion characteristics different from what the predistortion algorithm was designed for results in increased distortion.
Well, then you agree that there is a differece between..and it depends on the headphones!
This was finally the question..
There was also somewhere a previous discussion ongoing that not each headphone works well with DIRAC due some reasons you stated before which is clear and nothing new..
But as I said, for me personally it sounds much better. Maybe are my 180 Euro headphones made of cheap quality, my ears need a doctor or I'am a promotion victim

I got rid of my stock firmware before I had a chance to try the Dirac stuff, but it sounds like it's very similar to Beats Audio, where a lot of the lower spectrum and possibly some of the highs are boosted. This generally makes a more "fun" sound for the casual listener but a lot of more analytical listeners will feel like it ruins the sound, especially if they own earphones that already have their preferred sound signature.
So basically: If your earbuds share a similar signature to the Find 5 included buds, you'll appreciate Dirac HD's effects. Elsewise, if Dirac happens to shape your buds' signature into something you enjoy, then more power to it.
Meh. My NuForce NE-700Ms are already plenty V-shaped (my only complaint being that I have to run 4khz into the ground because it can be harsh. I still recommend them to you out there looking for a quality pair of IEMs at a decent price)
Only for information:
With the Stock Music App, which is not really bad you can switch between DIRAC, Dolby or turn every sound improvement off. But you must plug your headphone in otherwise you have in the speaker mode only a possibility to select Dolby or turn everything off..
So you can compare a little bit better how it works for you...
A big reason I got this phone was the audio experience.
Now, I'm using LineageOS (as it seems most are) and I'm wondering about how its audio quality compares to that of stock.
From what I can tell, it's not using Dolby Atmos as stock does, and I'd like to have that. But, I'm not really sure of anything beyond that. Any chance we can add that in custom, non-stock ROMs?
What else is there we can do? It just doesn't sound the same.

The stock audio is the BEST, loudest, and clearest sounding phone experiences I've ever heard. Blows away any of the earlier HTC M7-M9, as well as the Moto X Pure/Play.
LoS has issues with the audio... It's not stereo, it's distorted unless turned down fairly low, but I think it's ok using headphones/ear buds?
About the only solution to cure the distortion is to turn the gain down using Viper4Android, or ARISE (which has V4a). It also has a great EQ, some like better than Dolby Atomos, but I prefer the Dolby Atmos. ARISE has a Dolby add-on, but not sure it works?

I tried this with AOKP, but I use the speakers too much and they still distorted or were really low with no distortion. So, back to Stock-ROOTed Nougat for me.
Hello,
I've had the following ROMS on my Axon 7:
MiFavor Stock OS (Android 6.0)
CyanogenMod OS (Android 6.0)
Lineage OS (Android 7.1.1)
Resurrection Remix OS (Android 7.1.2)
AEX OS (Android 8.1.0)
However, with all these ROMs I was never really able to tell whether audio is processed through the Snapdragon 820 DAC or the AKM/AK4490/AK4491 DAC.
I've been active on XDA to follow updates on audio and ROMs.
With the stock ROM's I do think the 'super HiFi' option really made the phone use the AKM/AK4490/AK4491 DAC.
Also the audio playback through the built-in phone speakers was amazing (but limited in loudness because European ROM)
On LOS 14.1, it was said that the ROM used the HiFi DAC but 'distorted audio playback' was still mentioned as a bug.
Audio playback through the built-in phone speakers was poor (especially mids would give a cracking noise)
On RR OS (Nougat), I basically has the same as on LOS 14.1 (mainly because RR OS used LOS as base).
Now I'm on AEX OS and I do think the audio sounds much better than before.
(I flashed the AK4490 patch (not sure if this does anything... I've also read that custom ROM's have the Hi-FI DAC enabled by default) and I also flashed Hell'sGate Kernel (which seems to contain the CAD Audio Driver).
Audio playback through the built-in phone speakers seems really good again.
However, I'm still actually confused whether my phone actually uses the AKM/AK4490/AK4491 DAC.
I've read stuff in this forums about 48 kHz vs 192 kHz playback.
AK4490 patch is supposed to enable the AK4490 DAC but I'm still a bit skeptical whether it really does use the DAC properly.
CAD Audio Driver (included in Hell'sGate Kernel) oversamples to some maximum frequency or something.
And then there's this thread https://forum.xda-developers.com/axon-7/how-to/stock-roms-best-dac-t3650231 , so yeah, skeptical.
So far, I do think the audio playback sounds good... but what if it could be better, right?
Is there a way to test whether the HiFi DAC is being used and being used properly?
Also, does Dolby Atmos and Viper4Android have a negative (or maybe positive?) impact on the output signal?
I thought Viper4Android had a max. processing frequency of 48 kHz..?
TL;DR: See the title of this thread
Cheers.
Dunno how to find out if its truly being used. But i got a question.
I read so many times now that the european version (A2017G) is lacking in terms of loudness for the speakers which i cannot really believe since my axon 7 (which is the G version) with stock rom (also G version) is the loudest phone i ever had. Its really loud. And also on maximum loudness the sound cracks a little depending on what you're playing (usually on high pitch sounds). So how can the us version be even louder? Wouldn't that break the speakers quite fast?

This is a huge mess ?
Look, you're overreacting to the whole hi-res audio thing. I'll tell you what we know, what I think, and what we don't. After that you can simply draw your own conclusions.
First of all, ZTE told us that the DACs used in this phone are the AK4490, and a low power one inside the AK4961 (this one is a codec, but it has a DAC too for some reason). If the ROM is not well configured, it will default to the AK4961 in theory.
Now, you may or may not believe me, but there is an audible difference with soundstage and bass between the 4490 and 4961. Let's keep this away from the hi-res talk for now.
If you use MiFavor (6.0, 7.1, 8.0, doesn't matter) you'll have the audio switch. If you toggle it while listening to music (Not poweramp because it'll crap out and you'll have to reboot) you'll find a huge difference in soundstage, and the bass is much more defined on the 4490. You can listen to both DACs one after the other on stock only, but if you used this phone for a while, you'll know when the audio coming out of it is crap or not.
About the old AK4490 patch: It's only for Nougat ROMs, and it's been integrated in many ROMs since it came out.
"Distorted audio playback" was about the speakers and it was because the driver was badly implemented. On stock the AK4961 is used for the speakers always.
I'm not sure if the "CAD driver" is in Hellsgate, where did you read that? Last time I checked we were asking Kranoner to add it but idk. But it doesn't oversample. It simply modifies some filters on the DAC driver.
And Atmos is designed for the speakers, so while it actually does work on headphones, it'll add a crapton of noise - i'd say avoid if possible. also it obviously won't work with hi-res. Viper4Android will add some noise if you crank up the highs too much, otherwise it won't be that bad. Both of them at the same time will make a noisy mess but it's possible to do.
And why do you care about the 48KHz sampling rate? Are you using files with more than that? Oversampling is just worse.
So now the Hi-res talk: Unless you really hear a difference, and unless you actually have huge 192kHz files, you should not give a crap about it. It's not like "if it's there then sound has to get better with it".
To check hi-res you can use dumpsys media.audio_flinger while playing something via Neutron or a couple more players (Not poweramp, again).

Back in the Marshmellow days, I was told that loudness was limited on the G-device software-matically since EU laws don't allow too loud phones or something. (I'm not sure if Nougat removes this software-limit but hardware-wise the U-device and G-device version are the same). I doubt the speaker would break but I don't know...

Nah, I don't use FLAC's or huge 192 kHz audio files (just simple Spotify premium actually...) but I was curious to know what these discussions on the forums on 48 kHz vs. 192 kHz were all about.
'dumpsys media.audio_flinger' reports 48.000 Hz for me.
EDIT: What about 16-bit vs. 24-bit?
I only upgraded to AEX Oreo yesterday but I do have to say I find the audio playback (through headphones) MUCH better than on any custom 7.1.x ROM I've had (with the same audio mods setup).
I actually already found audio playback really good on the 7.1.x ROMs (through headphone) but the improvement from 7.1.x to Oreo is just too noticable to let it slip by.
So it made me wonder if it can get even better than this

well I'm not sure if that's the case, but I can assure you that the speakers got much louder after Nougat. Headphones have always been exceedingly loud, especially with the stock low impedance IEMs (with Poweramp I had to use them at volume 2 or maybe 3, so I just made it have about 50 volume steps to get at least a little granularity). Since Nougat I have been using the volume level at 1/3 with my 32 ohm over-ear headphones, so i'd say it's too freaking loud...
Now, I wouldn't be surprised if the volume limitation is just not working with Poweramp's sound engine, because everything else is much quieter. For example I have to crank the volume up to 2/3 on youtube to have comparable volume.
Supposedly if you installed US firmware back in the day you would get rid of the limitation. but installing firmware from another model was not that common, and i never tried it.

Back at it again:
1- nope, custom ROMs weren't using the AK4490 even after about a couple weeks or even a month of the creation of that post. Of course they weren't, otherwise why would the patch exist :silly:
2- It just didn't work. Now it would work even less since they should use the DAC properly.
I've used AEX from the build previous to the Oreo DAC fix (at least the first one, now there's another one seemingly) and the difference was there. AEX also has better sound than any other ROM overall (even stock mifavor).
3- Thanks, I didn't know. I mean I'm using hellsgate 2.0 right now xd
4- There's very little info about this. I guess it actually does oversample, but I was talking about upsampling on the music player app.
From what I've read around, most modern DACs oversample to a ridiculous frequency, in order to make output filters simpler and to have better highs (non-oversampling DACs have lots of harmonics on the highs). But it's not related to upsampling, say, an MP3 to 192kHz. Just take my word, doing that is bad.
5. Hi-res is discussed everywhere. I believe there's a noticeable improvement in the high frequencies but not important enough to use Neutron player.
16-bit vs 24-bit is actually quantifiable though. 24-bit audio has less noise than 16-bit.
And of course audio_flinger will report 48k ? you need to play special 192kHz FLAC files on a special Hi-Res player (e.g. neutron) with special configuration and on non-Oreo ROMs to be able to use hi-res
You'll need root and a terminal app.

Now look at line 1912.
I need to know this result in two scenarios. Once when playing music (eg a YouTube video) with headphones plugged in and once with nothing plugged in.
When playing music we know our HiFi DAC is being used if the line reads "HiFi switch sel ak4490" and if it's using the standard DAC it shows "ak4961".

I have two Le Pro 3 phones here, one has Lineage OS 15.1 and the other one is out of the box with stock rom. So it is very easy for me to test the sound for both roms at the same time.
I know already that stock rom offers the best audio quality with the built in internal spakers. Stock rom offers fuller and richer sound with also more bass with the internal speakers. There is no chance to have similar sound with the internal speakers using a custom rom without using any audio mods like dolby atmos or viper.
But even using these sound mods I was not able to tune the sound of the speakers similar to stock sound.
I made some longer sound tests with both phones and found that there is one big difference between stock and custom rom:
As the phone has Stereo speakers (upper one and lower one), the eqalization of both speakers is totally different with stock. While the upper speaker offers much more mid-range frequencies and nearly no highs the lower one is giving much more bass and high frequencies but nearly no mids. This effect is present with and without activated dolby atmos in stock rom.
So it seems to me that the stock rom uses different settings for left (upper) and right (lower) speakers. With headphones, both channels offer same sound, of course.
Using Lineage OS 15.1 without any sound mod, both speakers offer very similar sound characteristic. I am not able to hear different equalization between upper and lower speaker. The upper one has the same amount of highs, mids and lows like the lower one.
By using dolby atmos or viper, the sound quality improves impressingly but this effects both speakers in the same way.
Maybe becouse of this difference there is no chance to have the same sound characteristic with the speakers like in stock rom.
And maybe this info could help someone to imrove speaker-sound with lineage?
Hi @walking-desaster , maybe you can give the MIUI Ares ROMs a try and compare the sound quality.
This ROM are based on a clone of the X720 (Cool Changer S1 with JUI ROM) and should use similar or updated drivers with Nougat and MIUI 9 on top.
The ROM is posted both on 4PDA and by @tsongming in his Megadrive.
I am not sure why the version posted by Alex_Agir is different from Tsongmings megadrive, maybe he can explain.
Would be interesting to learn your experience.

There is no difference between the Rom Alex_Agir and the one on my Megadrive and I gave him credit.
I posted the file on the megadrive and will soon add it to AFH as well. Just to make it easier to get to. Alot of people use browser that do not translate sites as 4PDA very well. Plus, the Megadrive link includes additional addon, to enhance the MIUI Ares ROM, and to make installation quicker for someone new to Miui.
Like @walking-desaster, I am a big fan of audio.
In fact for me, as a hobbyist recording musician, its usually the most important aspect of my phone. But, I too have multiple Leeco's ( four) so its easy to tryout everything. Plus, I still have my old iPhone, which I use like an iPod for my car.
I agree that stock EUI sound is far superior, and modded EUI's out there seem to be just short of the stellar sound offered by stock. but its close. My issue with stock is that its using marshmallow, which I can't stand.
The Miui Ares rom has the best sound quality of any Rom that I have used since stock. To go on Stock sounds better with Dolby and custom Roms sound better with Dolby. Both sound better with Viper.
Viper is better than Dolby because it has all of the same tools. such as EQ and compression but takes it a step further with the option of being able to add profiles. The profiles include packets of .irs files. Which are convolution reverb impulses ( which are actual acoustic measurements of rooms or speakers) these convolution files allow you to simulate the sounds of room reverb and speaker acoustics. They are similar the impulse responses used in electric guitar amps and headphone emulators.
You can download profiles from my Google drive: https://drive.google.com/open?id=1KtNtBOw1Hj7Rw4OVT2wWdE1ujDAZgo9x
or better yet use these instead
Use the profiles from my drive but use impulse files from sites such as these : https://forum.xda-developers.com/showthread.php?t=2372750
Note, you have to manually add the profiles here: storage/Viper4Android/
BTW, were you aware the Leeco CDLA headphones has a DAC chip and use Dupont speakers?
***(Update: I've found a fix! Being in stock room and installing Ainur Sauron mk ii.ii has improved the frequency response of the phone. The volume is same as before (but it's still adequate), so PowerAmp/Firefox/VLC is still much louder. But now the sound signature is similar. No more pathetically weak bass and overly bright sound!
BTW, Ainur Sauron doesn't work on LineageOS, RRemix, etc. I think Ron's made with Shivam Kumar Jha's trees are incompatible with Sauron. So I'm using stock 318)
I'm sure I'm not the only one that has noticed how badly Asus has tuned the audio of this phone (esp. through the 3.5mm jack).
The Snapdragon 636's SoC is capable of providing pretty decent audio quality. But in the ZMPM1 only the sound through a select few apps (Firefox, PowerAmp with hires 24bit + 88/176/352/384khz audio, VLC, etc) is good. The sound from almost all other apps and audio mods like V4a is pretty bad.
For example, the sound produced by Firefox when playing YT videos is quite full and rich and has a seemingly accurate and linear frequency response. The same video when played through the YT app not only has much less volume, but also has a completely different sound signature with reduced bass, harsh treble, and an overall tinny and compressed feeling. (BTW, it's definitely the phone and not my headphones/IEMs)
Now in previous phones I've experienced that Firefox's audio is not changed by mods such as V4a or other equalizers. This makes me believe that Asus has, for some reason, purposely worsened the sound (perhaps due to some issue with the amp? IDK)
So is there any way to revert/override/bypass the changes made by Asus in all apps? So far I've tried the following-
1. Used Lineage Os 15.1 by Shivam Kumar Jha. It boosts the volume so there's no difference in volume between the good and bad sound, but the sound is still bass-lacking and tinny in most apps while full and rich in Firefox.
2. Used Ainur Sauron mk ii - Didn't fix it.
3. Used V4a- Not only did it not fix it, but installing the V4a driver means audio is now capped at 48khz and 16bit, so even PowerAmp hires breaks.
4. Other equalizers- doesn't really remedy the problem, only masks it somewhat (that too pretty badly).
So is there some way to maybe modify the audio effects or mixer paths files to remove this? Or is this just baked into the device in such a way that it's not fixable? I hate being limited to Firefox for YouTube and PowerAmp hires for local audio, and not being able to use viperDDC/IRS for headphone compensation makes things worse. So any help would be very much appreciated.
For me with V4A sound is great by using Convoler/IRS mod, and some tweaks in compatible mode.

V4a just changes the sound, it doesn't improve it. And with it's 48khz 16bit limit even PowerAmp's hi res output becomes average quality.
Even if you neutralize the frequency curve with v4a, it can never improve the slightly garbled and compressed nature of the Zenphone's sound. Instrument separation cleraly suffers because of it.

I see. Can you give me an audio sample file where you could see diff clearly ? So i can test it our myself with with and without v4a, and might be able to figure out.
Thanks
man thanks for this post, i am raising this issue in asus offical forum and xda alos, but mostly people are only worried about the camera quality and gaming perfomance, nobody even in youtube reviews talked abut worst sound quality of this phone, i dont know why.
i even raised service request with Asus but they did not provide any solution, more and more developer need to fix in future custom rom. other else this phone is total waste, i am movie and music loving guy, the movie sound is terrible from earpone jack, in night when i want to watch movie and listen to music , i cant do it, because its not pleasant,
the speaker is good, but 3.5 jack sound is very very bad, i request all rom developer please fix this in your custom rom, as asus is not listening
There are kernel avaible so may there is a way to enhance or tweak the sound from that level, please do it, if i had know that this is the issue, i would have gone for RN5 Pro phone, instead of this one, i need a great experience, even phone selling at 5000 have clear and loud sound i had Lenovo A6000 Plus, which was almost half of this phones price, but man the sound was so great
Asus Please fix this in updates, other else this is waste, not only sound, there are many more bugs in this phone, Asus just rushed this half backed phone to market, the phone should be balance of Hardware and Software, only having good hardware at competitive price is not enough, you need to have a great software to use the hardware properly, asus missed onthis one
even the LED notification and front flash is of cheap quality, even in dark night or dark room LED notification does not glow enough why Asus why
Camera software is patheric, but thanks to some mod, now we can use Google camera, i will use it for few months and then sell it, because its not pleasant to use due to many software issue and some cheap parts used by Asus.
Update: Using Ainur Sauron while on the stock room and enabling FMAS drivers using the Sauron useroptions file improved the sound (I think, or it just might be me slowly losing my mind, lol). I've also increased the volume of hphl and hphr in vendor/etc/mixer_paths.xml to 12, that may or may not have had something to do with it. The volume is still much lower than PowerAmp/Firefox, but the sound signature seems to be more neutral. Using splitscreen it seems that Firefox @ volume 6 and YouTube app @ volume 10 sound almost identical, and both of these sound pretty similar to an ancient s4 (which has a pretty linear frequency response).
I received my phone a about a week ago and I agree, coming from my old oneplus one the audio was lacking depth, it had recessed vocals with high interfering in between, and shrill highs. After carefully listening many flac and other audio files back and forth on my old phone and Asus, I came to the conclusion that the entire audio output spectrum of zenfone max pro m1 is shifted towards the right, which explains all the aforementioned issues. I have posted the same on zentalk and I really hope that this issue gets fixed soon. Too bad very few people look for decent audio quality in budget segment otherwise this wouldn't have been an issue at the first place.
Those that are still facing this problem, I stock room+Ainur Sauron. I've updated the OP with some relevant info.
This sounds great. Don't know why all people are complaining about 3.5 mm jack sound. I can hear each and every note of all songs same as I can on my pc. I've tried a lot of different earphones/headphones (2 sennheiser, 1 flipkart smart buy in ear, 1 Sony (over Ear) don't know the model was my friend's, 1 boat and 1 Philips. All sounded different but were very clear and fine.

How to enable 'FMAS drivers using sauron useroptions'... I have installed Ainur sauron
So after all these days I've found the perfect fix for speaker and headset audio quality improvement, install viper4android xHiFi from magisk and tweak the setting to your taste. the best part is all these changes are global, so unlike music FX or similar apps, these effects will not be limited to music players. I was also able to remove the sharp audio output from earphones and the loudspeaker using the EQ within viper. The addon also processed bluetooth audio but I haven't tested it yet.
Bro ,i am on the same boat ,but got good quality output using vlc player with audio output set to Open SL ES..Do it ,live with it till we get an update from ASUS.
Since i Love music i flashed a custom rom and now i'm enjoying music as i use to. Shane on Asus for ****ing up the audio on the device
Easiest way if you don't want to root
Just install vidmate and listen songs in it.
Try it just once.
