Bluetooth stereo quality

I was playing with my friends Atom the other night (and I have one on order myself) and I wanted to see how the bluetooth worked. So, I used a bluetooth adapter on a computer to become a stereo receiver for the Atom. While I had no problems getting the device working, the quality seemed outragiously bad. I was playing an MP3 in Windows Media Player, and the sound played over bluetooth sounded as if it had a high pitched squeel over it the whole time. With this kind of quality, I question being able to use a set of bluetooth headphones with the Atom. The quality was not a problem in the MP3, and it sounded find out of the Atoms speakers. Was I having some other problem, or is bluetooth stereo sound just this bad?

On mine it sounds better on BT stereo than thru' speakers :lol: Maybe your pc corrupted the soundz

Well, I suppose "better" could be rather subjective. But when using the PC as a stereo speaker it sounded bad. I imagine with that kind of sound on headphones, my head would explode out of sheer pain. I'm certainly willing to accept that my PC bluetooth software could be causing problems, but I'd like to hear what others think before purchasing a set of bluetooth headphones. I would be describe what I heard as if it had been overcompressed sound with horrible high pitched artifacts. Would you say that the actual sound being sent to your headphones was phonically the same, ignoring the quality of speaker vs headphones?

Remember "Garbage in Garbage out" :twisted:

The same MP3 played on the computer it's being transfered to via bluetooth (and therefore the same speakers) sounds perfect. What I'm wondering is if bluetooth stereo quality is as bad as I've just experianced, or if it was something outside the normal "headphone" system that was causing this (such as poor receiving software).

Fortunately tonight while browsing the forums I came across the following,
http://forum.xda-developers.com/viewtopic.php?t=54621
This completely cleared up my sound quality issues. Sounds like what I'd expect now. Hope this helps someone else.

Tell me. Which settings did you apply? All or some of them. There are so many inputs you cannot even know ehich is which :roll:
I changed only Bitrate:
Bitrate 53 increased the frequency of breaks to almost one every 5 seconds. My original was the default 30 which was just fine at less than once every 2-3 minutes.
Am currently testing 35. Hissing is gone, but the ocassional cut is still there @ once every 2 minutes.

[Q] Audio Quality

Hi
This seems to not be mentioned in most reviews, but what is the audio quality like as an MP3 player over headphones or bluetooth?
Previously had an Omnia 7 and sound as good but too quiet so you had to ramp up the volume, thus creating noise.
Thanks
Paul

The mobiles that I have had do not compare to my old sony, creative players and my cowon s9 - I have jays q jays monitors earphones. However, they are more than serviceable when commuting etc as its one less thing to carry (and with background noise does it really matter?) but for quiet listening pleasure at home - I still prefer the sq of proper mp3 players.
The dell venue is ok once it starts playing music but you can hear static when no music is playing and you are running through the menus. From bluetooth in car it sounded great.
my palm pre on the other hand did not sound that good. my touchpad sounds ok.
I just got the sprint epic galaxy s2 this past weekend - and it has very good sound quality with the stock android player.
However, if you use cheap earphones - ie. ipod earphones you may not make much of a difference at all.

Distortion at maximum volume.

Hello a7 users!
So the audio experience on this device is extraordinary. But unfortunately, I've been having some issues while listening to my music on auxiliary. There's ton of distortion when I go to max volume. This happens when using the included headphones, my jbl car stereo system, and my Bose quiet-comfort 25s when noise cancelling both on and off.
I'm not sure if this is a defect with my phone in particular or if it is an issue with others as well. It's not THAT big an issue, as I never go to max volume with headphones because I like my hearing, and in my car, I can just go one step down from max volume and control the audio level with my car's stereo.
I have the US variant in the sexy quartz grey.
I am thinking it might be my audio source might not be enough for the beast mode dac. I am using spotify [email protected] extreme quality and some WAV files I converted from youtube. (Which is probably not a good idea as it's not a true WAV.)
If anyone has suggestions, they would be greatly appreciated.

I believe this is normal behavior. My old HTC m9 did the same thing

Oooh, that's unfortunate! Thanks for your input. :laugh:

anyone else find Bluetooth audio streaming quality not good?

OK I finally gave in my note 7 after I broke it today..And I am really trying to love this phone. Samsung's aren't perfect, but one thing they do well is stream clean music with *slightly* pushed bass. This works amazing in my car especially because I have a added subwoofer in my car.
I was really looking forward to the increased audio quality everyone says this phone has, but in my experience thus far, I am finding it incredibly lacking! Is it because I am not using the auxillary port?
In my car over Bluetooth the music streamed from it sounds okay except for there seems to be a huge lack of bass. I try to compensate by cranking the bass some on the radio, however it just sounds muddy. Not clean and powerful without being too powerful like the Samsung's.
Has anyone else experienced this, and short of rooting have you found any remedy? The part that sucks is the majority of the music I listen to comes from Spotify, and Spotify doesn't connect with any equalizers you can download. Only the phones operation system equalizer. Someone please chime in

Yea weak sound quality with Bluetooth
But when connected with 3.5 cable the quality is outstanding with the hi dac

Damn that sucks. I haven't used a headphone jack in damn near 3 years.

Are you rooted by any chance?

The amazing sound quality you're hearing about is from the wired connection. Once you hand off to BT, it's pretty much up to the device you're sending it to.

Well that's not true. You can play multiple Bluetooth devices and there is differences in sound. A iPhone, and galaxy, and this phone all sound different in my car stereo system and on my reciever in the house. Clearly 3 different sound profiles

Lg v20 is AptX/AptX Hd compatible. You should look for bluetooth IEM/Headphones/Speakers with those features and then you will get optimal quality sound for bluetooth. Personally have the LG tone platinum's with AptX HD and its the best audio experience I've from bluetooth earphones.

Yea and
Has weta rom

Sounds great in my car, Powerbeats wireless and Samsung level pro speakers. Nothing wrong with Bluetooth over here.
Sent from my LG-H915 using XDA-Developers Legacy app

Sounds amazing on my Harmon Kardon Onyx Studio and my Tones infinims.

This sounds great over Bluetooth with aptx. I have a a car stereo with aptx and it makes a difference. I was running viper on my old S4 before and I am pleased enough that I haven't even rooted to install viper yet. S4 sounded like crap over Bluetooth until I found viper with the appropriate convolver.

Weta included Dolby Atmos in his rom. Have you tried that with bluetooth?
I hear a big difference with it set to music and intelligent equalizer to open.
Lots of bass on my lg headphones.

But i love Hi Fi dac sound

You shouldn't have to root at all.
Try this app for play store
Equalizer FX
But in short no phone uses DAC once Bluetooth is connected. The only thing that may make your old phone any different is its Bass settings.

Does it work for Spotify?

Its a free app and runs in the background.
It appears to detect any media playing thru the phone.
I haven't tried it with Spotify, but my guess would be yes.
As I haven't found an app it hasn't worked with yet.
I've used it with Napster, Pandora, Slacker, You tube, web browser, lg player, and a few other things. And have been able to adjust the EQ settings every time.
Only glitch I have ran across is sometimes it doesn't start up or was killed off by the OS while not being used. So I have to open up the app once in a while and toggle it on and off to activate it again. But once that's done it usually stays on and continues to function until I stop playing media and stop using it for a period of time.

I just installed it myself and yes it does.
Keep in mind though these apps can only do so much with whatever hardware you're using.
Would be bad ass of the DAC could work with Bluetooth but unfortunately that's literally impossible since a DAC requires a wired source.

I downloaded it and yes it does help even with Spotify thank you very much. It helps some. I'm now getting the infamous static over Bluetooth.
I actually asked my dude to come over who has 2016 dodge charger (I have a 2013 300) because I was starting to think maybe I'm just tripping. I hooked my phone up in his car via Bluetooth and played a song by Migos (lol horrible artists but they have a lot of dynamic beats) I first played it on my phone with the said app running In the background. First thing he said is "why it sound like that?" I told him wait until we listen to the whole song. We then had him hook up his s7 edge via Bluetooth and there is a CLEAR difference. Much higher *quality* bass. Much more "fuller" highs. Not that the V20 does not get loud...That's not the case. The V20 will get loud but sounds like crap...
So to play devil's advocate. I pull out his aux cord from his center console and made sure I turned DAC on and played the same song. Yes. DAC does help with the quality especially when playing 320kbps music. It sounds great. Yet still, I still find the lows sloppy, muddy, and just not quality in my opinion. I expected alot more out of this phone audio wise, and call me crazy, I am extremely let down as I find the Samsung's have a much more natural, full, sound profile. Maybe I just prefer the Samsung audio profile vs LG's implementation. I know when it comes to clean low end bass, Samsung's have a clear advantage. Even with Bluetooth headphones.
I am going to continue messing with the equalizer app I downloaded and hope to find that great balance I am looking for. I may ultimately end up returning the phone. Seems fickle, but having to do all of this and use antiquated aux cords and rooting etc just to get the sound I want is overkill to me especially when there are no promos thru T-Mobile for this phone right now..
Rant end.

Try out Napster.
They have a built-in equalizer unlike Spotify.
And their built-in equalizer is a little better than the stand alone equalizer I mentioned earlier.
Just make sure your not running both equalizers at the same time. Also make sure that the phones volume is turned down to start off with, than increase once music is playing.
The phones output thru auxiliary seems to be a little higher than most head units can handle, when the volume is max out on the phone.
I also have a second device called sound shocker. It allows me to keep the phones volume low, but maximize the quality of the music and have high volume output from the head unit.
Go check it out at sound shocker.com
Also being on T-Mobile, dont forget you have the Hi-Fi settings. Adjusting the dB in the settings will also have great effect when playing thru auxiliary chord.

Oh....one more thing.... Under the accessibility settings under hearing, make sure you have stereo turned on or off to suit your preference.

Frequency variations

So I've had higher end pioneer, alpines, Kenwood's etc. I just bought an obscure android unit because 1 it was cheap and two it mirrors flawlessly. Here's my question... Across all of these platforms whenever I adjust the frequencies either in the phone os or (now) on the head unit when one, say low 60hz or lower goes up I lose volume on the other end of the spectrum. This has been steady across everything, phone's too LG's, Samsung, HTC 10 my current phone. Also they have all been both rooted and stock, it's becoming infuriating. Is this just a limitation in the hardware not normally noticed or simply overlooked by manufacturers because most people im assuming dont listen at loud volumes over these specific frequencies, ie earbuds and such. Or have I been consistently messing something up? I've tried at least 100 different apps. rooted aftermarket sound mods, bluetooth,aux input. All with the same result. And the tracks aren't necessarily the issue either because I've gone in and re-amatured (sorry) those as well. I searched and searched many a waiting in the car for the wife and found nothing. But I think the search engines hate me. Any input would be appreciated.

I've found the same thing with a lot of EQ's available via the play store.
However, I'd highly recommend a mod that's been around forever called Viper4Android - it does NOT act like those EQ apps you get from the app store, where increasing the bass actually just lowers the mids and treble. Without Viper4Android on my MTCE PX5 head-unit, I would not be happy with the sound quality. With Viper4Android, the unit sounds better than any other headunit I've owned (although, I am using an external amp as well). But even with the internal amp, Viper4Android brings the sound quality to new levels.
I've tried all of the sound-patch MCUs and none of them make anywhere near the difference that Viper4Android does. It has a "real" EQ (10-band) as well as lots of other very cool (and useful) functions.
Some people will tell you that you should leave the EQ on your radio "flat" becuase that is "how the music is supposed to sound", but that is absolutely false. That may be true *if* your car was a recording studio, where everything is optimal for sound-quality, but a car is about the furthest thing from a recording studio. A car radio with a "flat" EQ sounds absolutely nothing like the artist intended because the car environment is an absolutely horrible place for good sound-quality. Viper4Android allows you to correct the issues caused by the car environment *and* tweak the sound to your specific liking.
When it comes to sound-quality, all that *really* matters is what *you* think of the sound (not what someone else tells you it should sound like) - and Viper4Android is the best tool I've found to make the music sound good to *you*.
Just my opinion, of course.

Had it

Had V4A on my stylo 2+ and didn't sound bad but,and again I was probably using something incorrectly but same deal raise the high end and signal to my subs would fade out and vice-versa. I was hoping it wasn't a hardware limitation but it really seems that way. Best idea I've found it phone and headunit slightly adjusted to define the signals then an active preamp equalizer / crossover to split said freq and supply some of missing wattage from the poor audio chips at least in the Android HU's. But thanks for the input. :good:

I'm sure that not all Android head-units are created equal, but I can say with absolute certainty that with Viper4Android on my Eonon-branded MTCE-WWW Android 8 head-unit, I am definitely not losing low end when I increase the high-end (or vice-versa). In fact, I get the best bass that I've ever had in a head-unit and I'm actually having to go out of my way to sound-deaden and "tighten up" the car interior in order to handle the bass without vibration-related sounds coming from the inteior parts at higher volume levels! The sound is incredible - even from on-line streaming sources such as Pandora and Spotify (I have mine setup to automatically use separate V4A profiles for each music app via Tasker).
However, I do have a small extenral 45Wx4 RMS Kicker KEY180.4 auto-tuning DSP amp and a small Pioneer TS-WH500A under-the-seat subwoofer. Between the EQ and the Convolver in V4A (I personally like the BBE5 convolver .irs file), this thing sounds incredible. I was really concerned about sound-quality with this Android head-unit, but that turned out to be a non-issue with V4A (probably would have been an issue without it).
But even with the stock amp, it sounded really good with V4A (not quite powerful enough for me though). The Kicker KEY180.4 auto-tuning DSP amp definitely helps though. Love that amp. It has a higher noise floor than I'd like, but it sounds fantastic (I originally had an Alpine KTP-445U 45Wx4 RMS amp and the Kicker sounds *so* much better).
I would defintiely give V4A a try if you are looking for better sound quality. I feel that car steroes can benefit from 4VA even more than phones.
