Increase bluetooth A2DP quality (SBC -> MP3) - Galaxy S II Android Development

Hello XDA!
Hi have a Galaxy S2, I can found only a bad thing in it: bluetooth audio quality.
I have done some search and I'm sure that GS2 (like most other smartphones) uses SBC codec to send data over bluetooth.
The problem with SBC is that it reconvert your compressed files, such as MP3 or AAC, before sent them over bluetooth, so the final quality is terrible.
You can improve a little the quality increase the bitpool (use an highest bitrate for the conversion) but sound quality will never reach Directly MP3 transfer without conversion, for example connecting an usb stick to your stereo.
But there are a lot of discussion about ad2p sound quality on xda, so I think that you already know that.
I think that create mp3 codec to work with GS2 is hard and difficult, but I have found that Blueplayer for Windows mobile and Motorola with Droid X/ Droid 2 use A2DP Mp3 direct stream, in the specific motorola enabling the option "enhanced stereo" in bluetooth menu (absent in SGS2):

So my question is: is possible to make a port of blueplayer or motorola bluetooth stack for Samsung Galaxy S2? I think this is the only way to improve bad bluetooth audio quality on GS2.

Acutally it should be as easy as editing a config file.. (/system/etc/bluetooth/audio.conf) like this:
Code:
[A2DP]
SBCSources=0
MPEG12Sources=1

thanks for your reply!
I have tried that, but it seems make no difference for me, have you tried it?

With my Plantronic Voyager Pro Plus ( Pro+ ), bluetooth audio quality is quite good ( although only 1 ear ). When change to connect Pro+ with Moto Atrix 4G, I got bad experience.
But with wired good brand/quality 3.5" headphone, Atrix do better in quality

Jack audio on galaxy s2 is really bad in my experience, and usb output is only available in mass storage mode... Not really useful. So I'm trying to get better audio quality from bluetooth...there is also car dock from Samsung with 3.5" output, but I think that the final quality is like direct 3.5" output.. Very bad things from Samsung.

yea i don' get the audio complaints. i'm happy with the sound on my sgs2. used various BT earphones (sony, motorolla, nokia and plantronics and all good)

GS2 audio quality via bluetooth is way too far differrent compared to Xperia X8. X8 audio quality via bluetooth is good, while GS2 is not. :-(

I'm OK with the quality of the Voyager pro+, but in car I need to increase the vol., there's anyway to increase the conversation volume of the BT headphones?
Sended from my SGS2

This is a well know problem for SGSII (and probably other Gingerbread-based phones).

Google has fixed the problem in the AOSP builds, but Samsung hasn't integrated that particular fix in the 2.3.4 edition - hopefully it will be integrated in the upcoming 2.3.5 edition...

You can simply use DSP manager or Volume+ apps to increase BT volume...google it

Is teorically possible to change Samsung AOSP to Google AOSP? maybe with the upcoming Nexus Prime?

This helped me a problem with A2DP stereo:

I use Omega rom 2.0 (best rom). I believe it will help you.

I had lousy bluetooth a2dp quality on stereo jabra 3030. The only thing that fixed it was switching to CyanogenMod, since it uses AOSP bluetooth stack instead of Samsungs.

I even can't paired with SGS2. The stereo BT still can used with my Omnia2. Weir.

Bluetooth superiority

Dear all,
Going through many threads on BT functionality on WM2003SE, this memory just flashed back. I remember there was a permanently displaying (new) BT icon next to the signal strength icon when I was using WM2003SE V.2.02 (DCS's) and was impressed by its fast call transferability (no delay phone -> headset). Such icon disappears in the version 2.06. Now, there is only the 1.72-identical headset BT icon that only will display when there is an incoming call and it delays the transferabilty of calls to the headset
My question is, does anyone know what specific software do I have to reinstall to the v2.06 to reactivate such BT headset connectivity. If so, please also post the file. Thanks in advance .
Cheers,
HI
you need to go "back" to 2.02t ROM.
For some reason, is THE ONLY ROM around with a minimum BT support.

Do you have the registry of 2.02? I've been attempting to get a copy so that I can port over the good stuff of 2.02 to 2.06 and issue a CAB patch to help things along. Seems that no one is interested...
Since 2.20CHS is the most stable. I have uploaded the registry of 2.20 if you are interested.
FYI,
For the BT Handsfree option to appear.
You will need to have this registry key around.

Sorry to hear that. I was hoping folks would just compare it against 2.02/2.06 and deduce the enhancements entries.
Sad and sorry
Sorry to hear that folks.
Has anyone checked the option?
Why the "stereo behaviour"?
Any idea on how to fix it?
My few days experience with 2.02t1 is that it is a bit unstable, and BT handsfree produces the stereo effect on BOTH microphone AND headset.
Furthermore the relevance of the headset icon on top and the "BT headset enabled/disabled" message in today screen is a complete mistery. For my handsfree BT car kit to operate, I need to select handsfree in the BT devices menu, then "headset" icon appears, so it's confusing. Plus, if you have both, handsfree and headset devices active simultaneously, there is no way for you to know wich one has the priority.
We need some manual or the like. Has anyone some instructions available?
resco registry
can anyone please send the registry file to use with resco registry?

I am on 2.06 and the handsfree is not ideal at all. The only thing that really work for me in handsfree mode is when I want to have two party on my end . Since the audio comes out of the BT set and the handset simultaneously, it's great for local conferencing with a remote party.
Since I also have the BT Tools installed, it may had confused the issue.
In the end I switched off the HandsfreeProfileOn by renaming it to OFF. Use Headset mode and all is fine.
I also noticed that in Handsfree mode, it will switch off my BT headset POWER when I hang up the call and that is totally out for me.....
In the mean time, That could be all that we have with the current BT drivers.
I would hope the BT can do the followings:
-Stream Audio from the XDAII
-Real Handstree mode to work with Voice Command
-Buttom assignment on the BH device
Bt still needs improuvement
Hi, I fully agree with your "BT wishes".
It looks like the fact that no "official" 2003 SE release is available for XDA II, is related to the fact that BT support is not yet fully implemented.
Maybe 2.20 versions solves that, but time being I've been embarrased too wearing my head set in one ear, and my XDA in the other... kind of sillyness...
Since I do NOT have BT Tools installed, I think this is not the issue, but again, those are poor implementations of the Handsfree profile.
We are getting closer, but obviously not there yet.

New Philips MP3/FM/BT-headset with Caller ID and custom ringtones

Recently i bought the new philips GoGear SA2446BT/02

It's a very small clip-on standalone MP3/FM tuner, 4GB, AND with integrated BT headset, and small display for caller id, song and radio info.
Music pauzes when there is a phonecall, it has a standard 3.5mm mini-jack.
The earphone has an extension cord (can leave it at home when running or sporting) and integrated mic, the player has a mic also for use with a standard walkman headphone.
Easy file management with windows explorer. (MP3/WMA)
Also used as a mass storage device tru standard windows explorer without annoying software in between.
it is possible to put your own ringtone on it for calling AND it supports ringtone streaming from your phone (if your phone supports that) dunno about touch hd tho . . . . can someone tell me if so?
it has the new Fullsound system by Philips.
Comes with a USB wallcharger, softbaggy, USB cable and its easy to firmware upgrade with philips device manager or download.(tried it)
Here are the specs: http://www.consumer.philips.com/con...02_NL_CONSUMER/Flash-Audio-speler+SA2446BT-02
(sorry can't find english info yet)
Resellers are limited to Dixons (NL)(local shops and online) and two-not-so-good-el-cheapo-internet-shops . . . . where i don't wanna order . . . .so i got it in my local dixons franchise over here.
Price in local shop is 99 euro, online 93euro, OR . . . . .101 euro!(pixmania, not too good supplier i heard . . . . .)
It rocks with my new Touch HD, sound is good, you get some decent headphones with it (not as great as my sennheiser in-ears but those cost as much as the whole thingy so its not bad)
BT pairing is a piece a cake and connecting when powered on is quick, startup is also very fast.
it is possible to swith thru your music folders and it works as with standard file management and not like say ipod with playlists and stuff.
You can put all sorts of files on it to take with you, like a usb stick with a cable.
that's the only minor i have yet discovered, it has (due to its small size?) not a standard mini-usb but a similar yet smaller input.
Display shows
mode (FM/MP3)
battery status
BT connection
USB connection
song-info
FM freq
and yes . . . .caller id.
it has shuffle function and Fullsound system on/off.
on the very nice mirror-shiny side it has some colored lights for BT, charging and so.
the lcd display is very, very small but i think that will help powersaving a lot.
I will try to install some BT audio drivers on my HD to see if i can send audio from my Touch HD to it so i can watch movies with wireless sound.
(worked with my sony bt headset)
Well i will add my findings as they come, but for now i am very happy with this great solution, it works much better than any other BT musicplayer i have had (and sold)
OK found english manual on philips site:http://www.p4c.philips.com/files/s/sa2446bt_02/sa2446bt_02_dfu_eng.pdf
Looking at getting one too...
Does it drain the battery of your HD with the A2DP on?
How's the battery life of the GoGear itself?
These are what I found from the Singapore Website.

Great review, very thourough...thanks!! I had looked at this but the price made me hesitate, I think after what you've written I'll go ahead and pull the trigger..
Hi,
Just wondering if you had any luck streaming music from your Touch HD.
Does it playback well and are you able to control the tracks from the GoGear directly ?
Thanks
Nice one. Looks even better than the Jabra 3030.
Does anyone know if there is a shop for Germany, too? Or where I can order it to Germany? Even on Ebay there is no reseller...

Right - are there any news?
Guys,
As we've not heard back from Dutchxxl, I called Phillips customer support to clarify the A2DP support.
To confirm, this device unfortunatly does not support streamed Bluetooth playback from a Mobile device. It's capacity as a Bluetooth device is only limited to handling phone calls and that's it.
So, if you want to play your music, it has to be from tracks stored locally on this device.
This makes it a deal breaker for me. Such a shame, as it has superior sound and the Caller Id function would have been good.
Could anyone help with seeking alternatives ? I guess most of us would seek the ideal scenario with :
- Built in Mic with handling of our own headphones
- BT Call handling
- BT Music Handling (A2DP)
- BT Music Control (AVRCP)
- Caller Id (Nice to have)
The devices we've mentioned so far are :
- Jabra 3030
- Motorola S605 (New replacement to S705, but no Caller Id)
- Motorola S705 (Caller Id, but not so great Music handling apparently)
Any others ?
I use the Motorola S705 and i find it work pretty good.
Motorola T505
I have Moto T505 and like rock ,its beautiful have this in car. He have comand buton for navigate music, voice cole, etc. In my Rom is CVSD
My ROM 1.7 Dutty

sorry for b.Eng.
Any opinions about the Plantronics Voyager 855?
Except for the CallerID it seems to be nice...
From what I've googled, you'll be limited to only using their supplied ear mono ear bud.
Good for a corporate environment though.

Bluetooth headset for Diamond 2

I am looking for bluetooth headset for diamond 2 mainly for listening to music.
Any recommendation for this?
Samsung SBH-650 and Sony DS-205 are both under my consideration. Is the capatibility and sound quality good?
Thanks so much!
Hi,
I spent a long time searching for a decent pair of bluetooth headphones and I finally settled on the Sony DR-BT50. They're fairly comfortable, they have much better bass than most bluetooth headsets and the autonomy is unbeatable... I think that they're a good choice if you don't mind the size.
You'll want to use Advanced Config Tools to change the bitpool and sample rate settings on your phone but once you've done that you'll get quite a nice sound for wireless headphones.

I use the DS205 and I like it. I'm impressed by the audio quality - both from the phone and the headset. Used it in two meetings today and talk time of 5h wasn't a problem for that headset.

These are my bluetooth settings for Advanced Config Tools :
Bitpool: Very high
Maximum bitpool: 128 (but I read somewhere that 80 is best)
Minimum bitpool : 65
Sample rate: 48000 Hz
I don't really know if those are the best settings but it sounds much better compared to default settings with my headphones.
I use the Sony HBH-DS200. It seems to be very similar to the DS205 except cheaper, possibly because it's an older model. I agree with mrbister, the audio quality is superb, I prefer it to the quality straight from the TD2 itself, and I'm fussy about audio quality.
The only niggle with the DS-200 (and probably the 205 too): the volume control is not user friendly. You have one button which you keep pressed and the volume ramps all the way down and up again. if you just want to raise it slightly this is a pain. You're better off adjusting it on the TD2.
You do need to set the TD2's bluetooth settings very high (Bitpool: very high, max 90, min 80). The TD2 heats up quite a bit when streaming (possibly because of these settings) and the battery goes down quickly, but the link is very reliable, and you can still do other things like surf at the same time. I also stream internet radio via bluetooth, but that really does heat the phone and shorten battery life. Still works fine though.
I can't praise the Sony 200 enough, i'm getting another as a spare.
Thanks so much mrbister, NeoGreendawg and Pete_S.
I think I will go to buy DS205 because of the superb sound quality!
I think the ds205 has another kind of volume button compared to ds200:

The bluetooth headset is a different thing from the bluetooth handsfree? I have a Tech handsfree (shown in the attached image), and it can be used just for the phone conversation, NOT the music.
Hence, I would like to know whether I do something wrong, or I have to use a different device for hearing music.
Is there any audio lag/sync issues when watching videos? I'd read that this is a common issue with bluetooth receivers.
EDIT: To the OP, if you don't mind pricy canalphones, consider the ety8: http://pocketnow.com/index.php?a=portal_detail&t=reviews&id=993
@ jcan: Your bluetooth handsfree needs to support "A2DP" profile as well as "headset" profile, then you will get both stereo audio and handsfree functionality. If it's only "headset", you won't get high quality stereo.
@ Aisorik: I haven't tested video with bluetooth, but as well as the possible lag/sync issue, you might find the TD2 "runs out of steam" trying to play video and, if you've tweaked the settings, high quality bluetooth at the same time.
@ mrbister: Thanks. Looks like I should have got the 205 instead!
Thx for the answer, Pete_S!
Hi,
I tried a video with my BT headphones and the sound came through nicely as usual (no connection drops or background noise) but it was a fraction of a second late so, yes, it's slightly out of sync...
I haven't looked into it much yet but I seem to remember reading about a way to fix this with an option in Core player...

Was the video a tricky one (near to the capabilities of the TD2), and have you also pushed up your bluetooth quality settings? Guess I ought to try it myself as I have Coreplayer too.

Yeah, my bluetooth settings have been tweaked (see previous page) but I don't think that's the cause... Like I said, I read somewhere that you can delay the video so it matches the sound but I still haven't looked for the settings myself... I rarely watch videos on my TD2 and never with my BT headset so it's not really an issue for me.

Sorry, I forgot to check back
The delay in the audio is probably down to a buffer used for A2DP streaming. I don't know whether the quality settings would make this any worse or not.
The reason for the question was only to find out whether the TD2 has the processing power to do high quality streaming whilst decoding a demanding video at the same time.
But, like you, I rarely watch videos on it, so it isn't much of an issue, just curiosity

I don't think the bluetooth audio works for FM radio. That is what you meant, isn't it?
FM is probably connected internally after the A2DP encoding point, so can never be channelled through bluetooth.

Routing Music etc. through Bluetooth ?

Hi all
I have a Bluetooth Car Kit but it seems that bluetooth only works with phonecalls. I use a Internet Radio app and would like to route the audio through the car kit rather than having my SGS2 on the dashboard, listening via the onboard speaker.

Actually this is something I'd like to do as well. My car bluetooth shows as "Phone Audio" in BT settings if I could amend this Profile so it plays any music through the car this would be great!
On the standard player if you press the menu button you get a "Via Bluetooth" option fo this.

If I'm on a call and I play a MP3/or a text message comes through it plays over bluetooth audio.
I have the Motorola T505 car kit and route music (or phone calls) from my SGS2 to car's stereo speakers. Use pretty much every day to and from work; listen to Pandora or stored songs via Neutron player. Is this what you are ultimately trying to do?
My device has a push-button that syncs the device to a chosen FM channel; I then tune to this channel. The trick is finding one that offers lower static. Did not perform any other on-phone settings but can look tomorrow morning if helpful.
Sound quality could be better (much, much), but it's great to be able to hear my own selections.
Hope this helps.
I am particularly trying to use TuneIn (tunein.com) which streams radio stations over the net but there are a growing number of radio stations supplying Android and iPhone apps

Hey, that's a cool looking app (just looked up); will be downloading.
Hmmm, I have not come across any BT audio device that does not support both voice and audio, and I have several. Does your car kit doc state that it supports both (and maybe FM pass-through)?
Regardless of FM pass-through, have you tried completely removing the paring and then repairing? Reason I ask is because I just flashed a new ROM and kernel to my phone, and when I paired the Sony HBH-IS800 earphone (my gym rig), it showed the paired-connected symbol but when I started music, it played though the phone speakers only. When I checked the profile, it read "Connected to phone." I then deleted the paring, rebooted for safe measure, and repaired. This time, the profile read "Connected to phone and media audio". Was the first time ever seeing this with a BT pairing.
Something to try at any rate....

Look at my screen print - The BT shows as "Phone Audio" only.

As I was saying..... I've only seen one bluetooth kit that's phone only; the poster's screen shot above... Sorry sir, had never heard of Blueconnect (is it nice?).
I actually skipped over your post as was more responding to the OP, for which I am still uncertain which car kit is being used.
When shopping for a car kit, I keyed on the ones that advertised being FM transmit capable.
TuneIn claim to support Bluetooth but there are a few posting on the web from other TuneIn users with this same issue. TuneIn suggested I speak to by BT device manufacturer - a device for which I have feck all details. It works fine for phonecalls and worked fine with music on a previous WinMo phone. I think WinMo had options to allow BT to be used for more than just phonecalls. There are very few (none !) options within the Bluetooth menu. Thought I might have been able to Long Press on a paired device to get into further options but

If the OT screen shots the same setting I guess it will say the same.
Nah its **** but its a company car and I had no choice.
Though if I can get it to play music through it I will be a happy chap

Some questions

Hi guys.
I have a Xioami Mi 8 Lite some months and so far I'm loving the phone.
But there are 3 questions that I like to ask and discuss.
1º Sometimes I have Wi-Fi signal in max and don't know why the cellphone doesn't download data. It kinda needs to refresh to get data again. Example I'm using facebook reading news and then start watching a video but the video doesn't download, I need to refresh facebook and then it works. My girlfriend has a Redmi Note 5 and this issue happens too. Anyone had this and how to resolve?
2º When I use an external DAC by usb otg the audio sometimes has some strange artifacts and noises. I can only use my DAC without problems with USB Audio Player Pro app since it bypasses android audio driver. Can I change some settings in order to resolve this problem and be able to use any audio app?
3º Is there an ETA for android 9 to be released?
Thanks for your attention.
Best regards!
2. I also use an external DAC from FiiO and it will work always good with following combination: USB Player Pro as you mention AND the good right cable. The cable Is the key. I use the very special small cable from FiiO and since then no problems. Search for the right cable.

In my case, always have to start USB player Pro so that initializes the DAC. Then, after quiting the app, others can use it too, like poweramp or Tidal, Spotify.
Anyway for streaming and other apps, the built-in DAC is more than good enough to use, so I use it. Normally I use the DAC for high_resolution music files @24 but 96KHz and higher, in FLAC, DSD and MQA formats.

As far as I know android system bypasses internal dac when there is something conneted. USB Audio Player Pro has a proper driver to reproduce sound for external dac. The problem with USB Audio Player Pro is that a little expensive for an app to play music when there are tons of them which are free and maybe have more features.
The internal dac in my opinion is not that good enough. The sound sounds muffled and the amp is weak to drive headphones or in-ear phones with more impedance. I have an 1More Triple Driver and the sound from the internal dac suffers detail and power. With the DAC it becomes much better.

Agreed, DAC + double or triple drivers earphones are much better and I use them as much as I can. Again, try to find the right cable, that will make the difference. And most probably you can enjoy with other apps too.

It shouldn't be an OTG cable. I bought it locally at digitec. Ch, but I'm sure you'll find it on China / other online stores. Mine is USB-C to USB-B, there's also BtoB. Attached photo
