[Q] S4 active & Bluetooth APt-x - Galaxy S 4 Active Q&A, Help & Troubleshooting

I recently purchase the At&t S4 active and a pairs of Sennheiser MM-550X,
Those of you who don't know apt-x is codec for bluetooth to keep the sound quality as the original (really close to) source sound files,
in compare to normal Bluetooth which downgrade sound quality to near 120Kbps.
SGS4 active supposed to support this but on the web there's so little information about it,
So.. I want to know how can i confirm Mine got the Apt-x? from what I heard some android version Not support this..
Does Acid audio engine support this?
Is anyone tried?
Thanks!

Questions and help issues go in Q&A and Help sections
Thread moved
Thanks
FNM

Also interested, how to make sure that APT-X is working on new 4.4 Kitkat stock ROM? Thx!

Sorry for bumping this thread.
I would also like to know if there is a possible way of seeing if APT-x is active.
From my experience, I don't seem to hear any difference in quality between my S4 and iPad, but the iPad does not support APT-x.
The quality sounds terrible compared to a wired connection, loosing fine detail present in a 320kbps track. It also sounds compressed as well.

How is the sound recording quality?

Hello guys!
I want to buy this phone but the sound recording quality is importante for me. I´ll record meetings and, sometimes, from about 3 or 4 meters...
Can anyone say if the sound recording quality is good? My question is becuase it is waterproof... maybe it will make the recording quality below average?
Thanks!

It really depends.
I've seen some people say that it was bad (according to their opinion)
But I've also seen that said there was nothing wrong with it.
The Z3C has 3 recording settings (in terms of sound)
Silent, normal, concert (something like that) so I guess you'll have to play around with those to see which fits the occasion best.
Here are 2 random videos I found, And in my opinion the sound isn't bad. Based on my own experience it's not bad either, but I'm not you, you need to judge it by yourself.
I'd say go to a store if possible and just record some stuff. (Please note that the Z3C doesn't come with a build in sound recorder app so you'll need to get one from Play)

My experience so far is based on two scenarios.. Concert and alarm test messages. Both are absolutely great in quality! Using sonys audio recorder to even record stereo audio.

I have not done extensive testing regarding sound, yet, but from what I have done I am impressed with the default sound. It has a wide sound stage, but very clear. However, I have recently purchased Sony's STM10U Stereo Microphone which works on the Z3 devices. There is also Sony's audio recorder app that works with this mic to download.
It really adds a studio type control, blocking out all external sounds, providing a more focused sound. Great for concerts. Comes with a wind cover which is handy for blustery days. This way, I have all my sound options covered.

If you record regularly I'd suggest investing in a decent mini microphone that plugs into the headphone jack. I find the built in mic no better or worse than other phones I've had, but have not done any detailed comparison.
I have found the sound quality absolutely perfect with the Z3C!!!
I play in a band and have always been jealous of how well my friends iPhones have been able to record our band practices. My z3 compact is loads, loads better than my galaxy nexus or HTC hd2 but still not as even good as the iPhone 4 I'm afraid when it comes to recording at very loud volumes.
I'm also using the Sony audio recorder. It works well but the files are massive and can only be saved on internal memory.

LG Quad DAC Tips, Tricks, Etc...

Howdy All,
For those who have had a LG V device in the past you'all know what's coming - how do we trick the quad DAC into high impedance mode (HIM) or AUX mode?
For those who don't know here's a little background. The previous LG V series phones have had a very nice DAC and AMP setup which can almost meet the standards of audiophile quality. The thing was that in the later phones (V20 and V30 AFAIR) the software was designed to "smart switch" which mode the AMP was in. HIM and AUX mode settings had the loudest volumes and was corresponding to the headphone impedance value. The normal setting had the lowest volume designed for low impedance IEMs. Note that the AMP setting doesn't really have a bearing on sound QUALITY, just sound VOLUME. I'm guessing but the reasoning for this is to prevent blown IEMs and blown eardrums. I'm going to find the link for the old V30 quad DAC thread and some stuff tried and what worked in order to activate AUX mode and/or HIM. BTW having ROOT on the phone allows for adjusting this setting as needed, which is why I went with the unlocked version this time around. My pair of MrSpeakers Aeon Flows have low impedance but need power in order to drive properly and the AMP in the V series phones would only trigger normal impedance mode.
https://forum.xda-developers.com/lg-v30/help/modes-quad-dac-t3690567
So that brings us to the V40. Does it have a quad DAC? Yes it does. Does it have a smart switching AMP? So far my indications are yes it does. Do the old tricks from the V30 days work on the V40? I don't think that they do. I have multiple extension cables, which I use for triggering the AUX mode as well as an impedance adapter (50ohms I think). The old methods of using the extension cable, the adapter, and both don't seem to have an effect on the AMP setting. My Sony MDR-1As are much louder than my Aeon Flows...bummer for me.
UPDATE - Upon further testing with the help of this app: https://play.google.com/store/apps/details?id=com.apptrio.hi_fi_status I was able to trigger the AUX AMP mode and it kicked up the volume on my Sony's quite a bit! Unfortunately when I triggered HIM the volume of the sound did not change from the normal mode. Basically what I did was take a 2ft 3.5mm cable extension (male on one side female on the other) and plug it in WITHOUT THE HEADPHONE CABLE ATTACHED. Once the HIFI status app displayed AUX mode I then plugged in my HPs and BOOM, here comes the volume!
Anyways if you have anything to add or have any questions feel free to hit us up. When root is available I'll also make updates to this thread if need be.
Have a good one :highfive:
Is that why the volume is stuck at 75?

If you have your volume go up to 75 and it doesn't blow out your ears then it is due to the AMP being in normal mode.
I just say one thing:
Neutron player!
Demands some fiddling before you reach your preferred settings, but for me it's the best DAC player out there!

Have you tried the mobile version of foobar2000? As it's the preferred app for FLAC files and such on the PC, I imagine the mobile version is quite good as well. I wonder how it compares to Neutron Player. I definitely will give both a shot and compare.
On the note of music players, despite making fun of it (it's quite easy to do) and being certain it would fail, I recently converted to Tidal. The quality is really astounding, and the music library is almost as complete as Spotify/etc. Additionally, some albums are available as "masters" that are actually encoded with MQA!
Your right about Tidal. It sounds awesome. The price difference isn't worth it though.
Treesap! I'm comparing those players right now! I'm listening to metal (Tesseract), jazz (Yellowjackets), all flac, and so far I like both foobar2000 and Neutron. The built in player is not satisfying me yet, except for mp3 (I See Stars - Treehouse). Does anyone know if it's necessary to disable the built in effects to make other players work independently? That's what I did with v20. Just remember how different expectations and taste we all have in regards to music/sound
And maybe I should add that I'm just a regular user (with high demand on sound quality), who can't afford too fancy earbuds or extras right now. Any advice regarding good quality sound (budget price) earbuds would be very appreciated
Went back to Poweramp (poweramp-alpha-build-705) and so far it's the best one for me.
For anyone who didn't know, if you payed for the full version, you can upgrade it to high res.

Well I'm sure there's some tech guys here who can give us the correct details, but for me the answer is yes! After tuning it up for my ears, the Poweramp does it in a perfect way. If I play mp3 or flac it's giving me perfect sound all over, compared to the lg app were I had to tune it up for individual files.
have any of you engaged the DAC for streaming, for Google music in particular?
there was mention by some last year that one DAC player and an add-on app could do that for Google music. i just don't keep much on my phone and streaming is my way, so I'm still looking at taking advantage where i can. I'm running V4A on a rooted V30 now and looking at the V40's development.

Poweramp improving and improving
(Poweramp-v3-build-805-uni)
I realize there probably isn't much benefit from forcing high impedance but I do want to do some testing with it among other things so I'm curious has anyone figured out any tricks to forcing it with an extension cable or anything of the sorts. I'm still trying to find ways and it looks like similar ways done to the v30 isn't working the same way for our v40's

What settings have you set your Poweramp to? The LG app is sounding better and much louder to me.

Hope the following can help, and also, please correct me anyone, if my way of thinking here is some way wrong or misleading.
A assume you've already taken part of the Poweramp forum?! It's the only way to get the hi-res add-ons. And you obviously have to log in to be able to download.
I'm not 100% sure about how poweramp and the built in eq interacts, but after fiddling for a bit, it seams like what I'm sharing here works best when it comes to volume and sound. Have in mind our individual reference of sound and of course, what kind of earphones/buds you have (this is based on flac files).
You can see I've put replay gain on max in Poweramp settings. You can easily change RG in the eq later to fit individual album.
If anyone else have suggestions, please don't be shy

Speaking of the DAC, does anyone know if the V40 has support for MQA? The V30 has it, and they recently added support for it to the Essential PH-1, but no mention of it for the V40, just "high quality Quad DAC". I suspect that it does, because they probably used the same chip for the V40, but I see no mention of it anywhere, so far.

I just got this phone, if there's no audio route I could go rooting device before tehn I am retruning back to mate 9 !
good luck here
Mate 10 ALP-L29 on EMUI 9's audio (from headphone jack) is one of the cleanest sounding outputs I've heard using my triple driver hybrid IEMs.
Sad that NO ONE is talking about it!

Absolutely right. I've used this device for a Year now and I really don't see a reason for some audio enhancement software, since the sound is just great anyhow I play it. I've listened my favorite tracks thru wired and bluetooth headsets, streamed over wifi and bluetooth dongles, and couldn't find anything less satisfying than my other phones. I have been using V4A and Dolby Atmos earlier on my Note, but I must say I really don't miss it at all.
Not trying to criticize, just posting my opinion.

Agree on audio through wired headphones!
However, in the car, i need a little bit of control with EQ and Soundstage / Reverb, and V4A provides those options. ATM, I'm using RE Equalizer and if only it's stable (enable / disable the switch to make it work), I don't feel the need for V4A
My. 6p was much louder with viper than mate 10 pro on aux. Can't agree it could be louder and more bass sound.

What's the sound quality like?

I've heard that the front facing speaker is pretty bad from this thread: https://forum.xda-developers.com/red-magic-3/help/red-magic-3-sound-t3936225
I was wondering what other users think, how does it compare to the speakers on the Galaxy S8/9? (I know that the ones on the S10 sound good enough). How loud do the speakers get? What's the DTS apk which was mentioned in the thread I linked? Do you guys think the sound quality can be fixed with root access equalizers like viper4android?
Also is there a reason why the real life reviews forum is empty? I can't seem to find many reviews for this device, so I'd love it if more people would post their impressions!
The sound quality is excellent if you use v4a to tune the speakers. I've suggested it a few times but nobody has done it.

Differences between models of Note 9.

Most of us have known for some time that China and the USA get the much faster better designed Snap Dragon vs the slower junk Exynos that gets dumped on the Indian market.
This we knew. But as I am studying the circuits this is not the only difference.
Anybody collected info in more detail on the differences ?.
For example an article pointing out all the differences ?.
Right now reading the Wiki article on both phones and even that does not go into the differences in detail.
FYI I just discovered that the Audio quality output also differs. As in the Audio Dac used differs between models.

I'm not so sure that sound is going to be different. This may be about software settings. Try this: Download and activate the Sound Assistant (free from Galaxy Store), as well as going to Sounds and Vibration > Sound Quality and Effects > Dolby Atmos and making sure that is enabled. It can make the difference between mono and stereo on these phones, among other things. Sound Assistant gives a number of additional fine tuning settings, including there being more gradation on the volume.

Thanks but that was one of the first things I tried.
I made the mistake or ordering the wrong audio IC that is how I discovered that the DACs used differ.
Then I went looking for differences and found no info. Hence the post.
