Hi,
What do people think of the audio quality of the Hermes in terms of playing mp3's though the headphones. I notice I can hear the background noise floor (hiss) when playing mp3's, it's not too bad but noticeable. Is there any way to improve this?
I have noticed the audio quality gets very poor in some video and audio files with Vega speakers or my Sony headphones.
This happens when volume is above 75% , the sound gets messed up, first I thought it is because of weak and cheap Vega speakers but when I tried with my headphones it is the same. Of course there is nothing wrong with the files as they are played perfectly on other devices.
I tried different media players and the result is same.
I'm running vegacomb 9n and 8.1 previously. Does it have anything to do with audio decoding or its same on all ROMs?
Thanks
Poor audio quality at high volume is a bug of vegacomb roms.You have to downgrade to 2.x roms to get good audio
It is noticed that while listening through headphones that the sound is being affected by some sort of 3D/spacial/EQ process that might give the impression of "punch" for movies but at the expense of phase-y sounding vocals and smeared high notes for music.
Yikes. Thst stuff is not good for music quality. No way to turn off? The settings options seems kind of scarce.
After playing around with various music players and headphones it seems that the audio is now OK.
Not sure what happened. It may have been a headphone jack issue. Audio sounds great now.
Oooops!
There is an issue with sound quality. Compared it to a Rockbox'ed Sandisk Clip Zip with a very wide stereo track 2-channel stereo track (fyi -- Brook Benton's "Kiddio" 1960). There is some EQ bast boost and high frequency crossfeed that narrows the stereo separation. I'm going to boot from CM and see if the problem persists.
For video I would not notice the issue, but could get to me listening to music with my Klipsch S4 buds.
Update:
It is not bad. Seems part of the issue is low gain which can be increased with Volume+ or other similar app function.
Volume+ did the trick for me. Jamming to some Coheed at the moment. Sounds as good as my other tablets now
The problem was never with volume -- I think stock has plenty of volume for driving Audio Technica ATH-900x. The problem is with some sort of audio processing that affects the soundstage and frequency response.
I am not hearing it using the Google player app. Gain is not the same as volume. Both need to correlate or weak quality.
SRS processing is used and applied at the headphone output. See HD+ file \system\etc\srs_processing.cfg
This is what I use, have my settings set to Jazz "my preference", audio sounds great, not talking about low resolution MP3's.

I understand the config issue, but I am not hearing it. I should hear the sound manipulation with cymbal decay as example, but not hearing it. Weird.
Playback in CM 10.1 has the correct stereo image.
so am I
so am I ,after checking
Hi,
I'm having issue with Note4 sound quality. While listening to some music or watching movie at low volume (30% or lower) on my non-stock (NuForce NE-600X) headphones I can hear repeating crackling. This is happening mostly when there's some silence moment in the movie or music... It looks to me like in-build amplifier has some problem to amplify low-value input signal and, so instead of a silence on the output I'm getting random scratching/crackling noise. The interesting part is that I cannot reproduce this issue on stock headphones...
Is this general Note 4 issue or is just my unit faulty? This is my last day of 14-days exchange period
Cheers

First I need to add that I find the so much advertised two DACs of the Axon very highly exaggerated in terms of power. They are just too weak, even compared to my previous Note 3, both on headphones and speakers.
Second, they seem to not be able to be effectively used on almost any app since 98% of apps do not utilise them by default and one cannot change it.
If you tweak Dolby Atmos a bit you can get it to amplify the general audio output, both on speakers and headphones, and this is why I use it predominantly. I am on the B09 update on A2017G and it is still very buggy. No matter what setting I choose, i.e. Music, Voice, Game, Custom, when I leave the Dolby Atmos screen it drops sound for a second and always resets to Movie, no matter what. Also the sound regularly interrupts, especially when unlocking screen or doing things in the background, or just on its own.
What annoys me most however from when I bought the phone is that at very low or low volume (only on speakers), when there is speach or the music starts, there is some kind of hissing, ss/sh-ing sound corresponding to the words said or the tiny beats of the music played. It's like a background noise added on purpose simultaneously with special, mostly high frequencies, i.e. words, tiny/starting percussions or similar, no matter the Dolby Atmos setting. This noise stays apparently at all times, it just is not heard when more, mostly low and middle frequencies get in. This "noise" is not available when no Dolby Atmos is used, however the volume then drops by a few levels down. Good or bad, Atmos also adds some spatial effect to the sound, which is why I like it for...
Does anyone of you, an A2017G or A2017U user, observe similar behaviour on your device? Is Dolby Atmos working better for you, i.e. unconditionally steady settings, no low volume added speakers noise, no sound interruptions?
I also noticed browsers do not get use of the DACs/Dolby Atmos, i.e. YouTube, online videos, many video players. My favourite before Aimp was unable to do so also so I had to transfer to Jet Audio and PlayerPro, both of which can work with the Dolby.
Why did ZTE add (two) DACs when they couldn't be used by 95% of the apps and games by default and even manually, also there seems to be no gain in output at all? Was this the case with the Lenovo Phab2 Pro's Dolby Atmos? For the "regulated hiss" (not present on headphones at all) I cannot currently watch any movies on the phone with Dolby Atmos enabled, unless at very high speakers volume. It hisses so badly every time a word is pronounced or some subtle 'invisible' sound plays. The same is with playing music...
I dont use Dolby when I listen to music - it makes everything so much worse and much quieter. Listening to flacs on stock music player with Super HiFi on. No hisses on low or high sound levels. Silence is silent. as for speakers - no hiss also.
ZTE did not add 2 DACs for music, 1 is for music other one is for audio recording which is records at 128kbps. and quality.. I dunno it's quite clear, I had recorded a room full of people, with two girls singing and some people chatting in backgroud and I can hear everything. but sound itself if on the lower end, girls vocals are lower than they are, everything seems shifted to lower sound spectrum.
Tooks some time and checked spectrum of that sound file 50-2000Hz. everything over 2kHz is just a noise.
and a little edit: it records nothing less than 50Hz - total silence there.
The stock player is OK but it's lacking on features, also not sure if it can play video.
I have noticed the low volume speakers "noise" with Dolby on when watching movies using almost any player - VLC, BS, MX and more. If I go above 30-40% volume it seems to disappear, but more like you don't hear it and it stays. I say "noise" but it is like a hissing/ss-ing sound added to sole frequences only, i.e. speech only or single instruments. When more frequencies get in, you don't hear it. Weird these don't exist at all with the Snapdragon amplifier, i.e. when Dolby is off.
https://community.zteusa.com/thread/12853, here is a similar thread in the ZTE USA community. I believe it has something to do with the Axon's own amp or its software and happens at low volume only. There was a thread in Reddit exactly about what I am reporting but I can't find it now.
If you go to your phone's Music\Settings\Dolby Atmos app, then move all sliders up you will notice that it significantly increases the overall volume when Dolby is on. So it's not low, if you change it, it boosts up the volume by at least 30%. On another note, the Axon's mic recording quality is quite poor/muffled, even compared to the old Note 3, hopefully they will improve it at least a bit by some future update.
I bought the A7 exclusively for its audio capabilities so am disappointed that I have to report insufficiencies in this exact area.
Does your Dolby Atmos set itself to Movie only if you exit the Music app? Are there any drops in sound when it's on and you do something in the background?
There are two DACs. "AKM AK4961 DSP CODEC, which can be considered the primary chipset for Hi-Fi audio playback and recording. The AKM AK4490EN DAC is an independent Hi-Fi audio sampler". So AK4961 works in standard mode and AK4490EN in Super mode. ADC is only in AK4961.
You can consider rooting your device and install ViperFX or the whole A.R.I.S.E. sound system. That will solve all the problems with sound output. However the sound recording filtering is surprising, leaving only the vocal spectrum is not normal. There should be a setting somewhere.
I have the Chinese A2017 model running Oreo & have just noticed this hissing sound which can be heard at lower volumes when I keep speakers close to my ear. I don't hear any hissing sound using headphones. I wonder if it's always been there or it's a hardware/software issue. I'm probably gonna hard reset the phone to see if it goes away. Anyone could fix it?
