[Q] APT-X HD Bluetooth Audio

What is the story with APT-X? I am starting to see bluetooth headphones and other "receivers" supporting this, but I am not finding any information on which phones, mp3 players, or other "transmitters" support APT-X. Can anybody shed any light on this subject?

Would like to know this as well.
No point in getting a new phone if this isn't supported, at least I will have reasonable audio quality through bluetooth if I get a headset + phone with this.

...bump...

apt-X is a lossless codec for bluetooth audio, MUCH better than A2DP.
If htc (for example) want´s to pimp a phone with it, they have to pay licence fee to CSR. As there are only a few bt receiver with apt-X, they will not pay and implement it (instead they get crappy "beats")
I think, apt-X is only a kernel-driver, no hardware, but not sure about this.
If so, a kernel chef could cook some additional codec in, but this is not open source codec...
I would LOVE an apt-X enhanced bt kernel for my sensation!

[SOLVED] aptX support for the Note 3 (US/European/Korean version confirmed)

UPDATE January 7th: Posted the log which confirms the presence of aptX
UPDATE October 16th: AptX confirmed. I tried it with my bluetooth headphones (Harman Kardon BT). It connects via aptX(LED flashing four times)
UPDATE October 5th: According to a recent live chat, the US and European version do support aptX. The Korean version has it printed on the back of the box.
I just had a customer chat with Samsung US. Here's the transcript.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
Samsung: Hi, thank you for contacting Samsung Technical Support. How may I help you today?
Visitor: Hi, I'm currently using the Samsung Galaxy S 4 and I would like to preorder the new Galaxy Note 3 but I need the bluetooth protocol aptX that the Galaxy S4 supports. Do you know if the Note 3 also supports aptX?
Samsung: I understand your concern.
Samsung: I'll be glad to assist you.
Samsung: May I place you on hold for 3 minutes, while I gather the information on your request?
Visitor: Sure. Thank you very much.
Samsung: Thank you.
Samsung: Thank you for being on hold.
Samsung: I have checked with the information and I would like to inform you that (aptX) bluetooth profile is not supported by Note3 device.
Visitor: Ok. Thank you very much for helping me out.
Wonder who had the great idea to remove aptX... .

The unboxing videos show that apt-X is specifically mentioned on the back of the Note 3 box, so I suspect the Samsung rep is incorrect.

If this is correct I will pull my thread immediately.
But I could not see any aptX on the back of the box in this unboxing video
http://www.youtube.com/watch?v=gxf3btdm0C4 After 11 seconds he shows the back.

I'm sure I've seen a video with the apt-X logo on the back, will try to find it again.

Ask Supercurio he might know the answer...

What's the use of this "aptX" ? I never heard about it ! ^^

AptX is a bluetooth protocol. It's an audio codec. . Standard aptX goes up to a bitrate of 352kbps. Best mp3's only have a bitrate of up to 320 kbps, so the remaining 32 kbps don't really matter.
There are some other versions of aptX such as aptX lossless with the capability of much higher data rates.
The advantage of aptX is its convenience. Adapter attached to the sound system, switch bluetooth on on your aptX device and connect it. Done. Now you can listen to your mp3 collection without any further losses in quality.
For guys who like to listen to lossless music it's not the right choice of course.
But you cannot hear the difference between a 320kbps mp3 and a let's say 800 or 1000 kbps flac anyways. If you don't believe me do a blind test with foobar and if you are one of the fortunate few, who actually are able to hear the difference, well congrats.

If the recording is exceptional I can take that challenge.

Ok, if you have a great recording maybe you can hear the difference when you really focus on the recording. But where's the joy in that?

Well, try it yourself. Get a QUALITY 96/24 or 192/24 or heck even a quality 48/16 file and encode it to FLAC or mp3 on your own. I have a bunch of classical, flaming lips, Gabriel, king crimson etc recordings and the difference is night and day on a capable system or with some good cans. Not everyone can appreciate and many more will care less because they've never heard the difference. You'd be amazed at differences that can be heard playing a movie at reference level and what ever is considered loud in your household. I myself rarely get to enjoy movies at that level. Mp3 and aac needs to die already. Recording artists are partly to blame for this.

Maybe they are able to develop a codec in a few years, that has the size of a mp3 but is lossless. But back to topic.
I hate it when they announce a new product like the Note 3 with all the features and stuff and the customer support doesn't know **** about their own products. Some say yes, some say no. Some say they don't have the info. Who else has the info if not the manufacturer? Ridiculous.

apt-x as far as I knew is included with the Note 3.

I need this confirmed. No speculation.

It has it :

back of the box at 17 seconds in

Considering Samsung purchased CSR who OWN Apt-X it seems unlikely in the extreme that they would go backwards and not support this since it has been on all their high-end stuff since the S3 (and lots of their less high-end stuff also). Add to this that they make a number of Apt-X capable accessories and it seems even less likely.
EDIT: ...and yes, it is very obviously on the box in that unboxing video.

It seems there are different versions.
@WILD9: Thanks for the video. As the guy mentions in his video it's the Korean version. On the video I posted on the first page, he shows the back at about 11 seconds. There's no aptX mentioned on the back. I don't get it why they release different versions without aptX... .
Here's the link of the video I posted: http://www.youtube.com/watch?v=gxf3btdm0C4
EDIT: After watching your unboxing video, it's pretty ****ed up to see what kind of accessories they all have included.

Possibly something to do with Exynos? Does he mention which processor it has, I have no sound here.

In the description it says 2.3 Ghz Quad Core. I'll ask which one it is.
Is there a way to edit the thread name? I would like to mention that the Korean version supports it whereas the European and US versions do not. Or at least it seems they don't.

[Q] Which Neo X8-H

Hello everyone,
This is my first post in a long time however I wanted to check before I buy.
Is the Neo X8-H the best Neo out? I have seen one on Gearbest for £115 and looks a great deal. I want it for the XBMC for movies and TV. I have a Neo 7 and want to upgrade, the Neo 8 is just the ticket and the "H" version appears to be the better one.
Thanks in advance.

Hi, I found H is best because of hardware capability decoder better than software decoder so X8-H is better choice.
Here quote (http://forum.xda-developers.com/showthread.php?t=2764694)
What is the difference between S802 and S802-H ?
-The only difference is the support for Dolby DTS video decoding .
S802 devices use XBMC or MX player S/W.to decoding the dolby and dts.
S802-H support hardware decoding dolby and dts ,which means no matter which video player you use, it will always have sound.

Bluetooth audio quality

Hey guys,
I was using a oneplus 3T in combination with the Bose QC35 headphones, the stock quality was extremely poor compared to the audio of an iphone (bluetooth connection).
With the use of v4a (root) or MusicFX (non-root) I was able to tweak the audio quality to a reasonable level.
I´m currently using a OP6 running android P, build PKQ1.180417.001, and again the stock bluetooth audio is poor. The MusicFX app does not work anymore.
What would be the best way to improve the bluetooth audio quality, or is the next update expected to introduce an audiotuner (With Bluetooth support) on the OP6 with android P.
Thanks in advance!

I'm using oos 5.1.5 with b&o beoplay h7 and Poweramp beta.
This setup supports aptx which improves audio quality. Also going for the beta of Poweramp is recommended, lot's of quality Options

Thanks for the reply, many people use Poweramp and the quality is better however the Poweramp equalizer cannot be used with Spotify..

Did you try to change the Bluetooth audio profile in developer options?

The QC35 only supports AAC and SBC, I tried both of them but there doesn't seem to be much difference. Aptx hd is unfortunately not supported by the QC35..

I use Op6 with Sony mdr100abn and Ldac is working. Bluetooth sound quality for me is better like on Note8.

Is there no workaround for this Poweramp issue, I mean the MusicFX not working? It even works on my cheap Xiaomi X4 so whats up?

[petition] 24bit/192khz Hi-Res Audio not supported on Mi A1: petition on xiaomi forum

did you know that the Xiaomi MI A1 has no Hi-Res Audio compatibility?
as seen on this thread on the official poweramp forum seems to be that Xiaomi did not add the latest qualcomm patch that makes possible to use Poweramp V3 with 24bit/192khz audio quality.
actually there is a petition thread on the official Xiaomi forum but we lack of votes to make developers know this issue.
note: maybe this is due to qualcomm royalties or patents like with QuickCharge but in this case the hardware is totally aviable to this function even more some custom roms have the patch included
i hope that with this post more people vote for this petition so this way users with stock rom can have a better audio experience on this device

Hi-res audio makes absolutely no difference to how music sounds, it's pure snake oil. Don't waste your time on this.
Don't be taken in by marketing gimmicks about higher resolution: it means nothing. Instead, watch the full pair of Monty explanations of the technical details of when bits and frequencies matter and when they don't.

Certainly not everyone notice the difference but some people myself included can hear the quality diferences, also even if its not a necessary feature this may be usefull for custom roms that want to have a focus on audio quality, also when using the "fake" hd mode on poweramp the sound goes worse and certainly everybody can notice that.

What headphones do you use with this phone that you are able to spot the difference between 16b/48kHz and 24b/192kHz?

You can you USB Audio Player Pro on custom rom like GZOSP or LineageOS 15.1 to get 192kHz/24bit direct to headphone.

Don't believe in usb audio player pro info. You should launch Terminal application, use "dumpsys media.audio_flinger" ater "su" to check the output like my attachment when it's playing.

the idea it's to have the feature on stock android, custom roms are great on fixing manufacturer software errors/mistakes, but not everyone want to loose warranty/screw their phones.

I'll try to gather more votes for this. But to be real, developers are too lazy to fix and add features since this is like an illegitimate child of Xiaomi and Google and they are more focused with MIUI phones.
Kindly also link in OP the link for discussion in Mi A1 subforum so someone can ressurect that thread.

You got right ! Lol 48 in output.
Due to the very powerful amp the a1 has i dont notice any "serious" difference comparing it with my mx4pro with fiio a5 amp that supports 24/192 (tested with the command you told me). Using sennheiser hd600.
