Are there any hacks for the Note 3 to increase BT Audio Quality? Tons for older devices from replaced system libraries (.so files) to you used to be able to edit the audio.conf file.
Anything like that for the Note 3?

Hi to all Devs and Pros here in the Forum,
I have recently been staying at a friend who owns an iPad and has a setup where he listens to all his music on his iPad and Online Radio via A2DP streaming to his Stereo via a relatively cheap belkin Bluetooth A2DP receiver.
The quality is absolutely perfect and ti sounds as though he has a wired connection.
I had my Iconia with me and also gave it a try. Unfortunately the sound quality was best said acceptable and nothing near the one of the iPad.
So I did some googling about it and found out that A2DP supports various codecs but only enforced one: SBC which seems to be a rather low quality option.
So my guess is Android / our Iconia is only using the SBC codec instead e.g. MP3 which is supported by most HW A2DP receivers todays (also the cheaper ones)
I found that there is a possibility to allow non-SBC codecs in Android to some degree by changing the following settings in '/system/etc/bluetooth/audio.conf'
Code:
[A2DP]
SBCSources=[COLOR="Red"][0|1][/COLOR]
MPEG12Sources=[COLOR="Red"][0|1][/COLOR]
I tried this but when enabling the MPEG12Sources I am not able to connect to any A2DP device at all (I tried 2-3 different ones).
On some place I read that to use e.g. MP3 as a codec license fees for the device manufacturer would apply.
So here are my questions:
Could it be that Acer has simply left this unimplemented? If yes do we have any chance to add this somehow to the system?
Or is it possible to change the settings for SBC to a higher quality?
I am looking forward to any of your thoughts or ideas about this...

I changed the MPEG12Sources to 1 and I can connect my Nokia BH-214 and it works fine.
On my N7: CM 10.1 and Equalizer the audio is really enhanced and enjoyable - *system wide* so, every app that has an audio output like TuneIn JazzRadio or RockRadio or any "stream audio app"pass through the Equalizer with the correct equalization and bass enhancement.
On my N4: CM 10.1 and Equalizer (so same situation recreated): The audio remain flat.
On N4 (CM10.1), i tested these mods in their respective last versions following carefully the installation process suggested and, as output hw two external boxes from BOSE - Companion 20 and two different BOSE headset over hear and around hear:
--- Awesome Beats: since this mod substitute the CM10.1 built-in DSP Manager do nothing but only with Apollo player so *not system wide* (why only with one selected player?)
--- AC!D Audio mod: it works *system wide* only with a little configuration in Clear Audio App. But the result is poor.
--- Audio Fx: worked only one time with poor results.
My elaborated question is: Anyone is able to get a good audio output? System Wide (equalize only one app is a no sense)? If the answer is yes, what i have to do to gain a good audio on N4?
Sorry for my English

Have a look at this thread it seems to be doing all you ask for for me.

HI All,
I only ever use my I9505 for Bluetooth audio. There is plenty of apps out there that boost the sound quality and loudness for headphone jacks and the phones speaker itself, but i am finding it hard to find any that deal with Bluetooth audio...
I currently connect to:
1) Bluetooth for my car - for music and calls
2) Bluetooth for my headphones i use at the gym - for music only
Any suggestions on how to get some better sound quality / loudness?
I currently use Player Pro music player - which has a DSP Sound Equaliser pack - but i am not too sure on how to fine tune that... It seems that the quality drops dramatically when i incease the volume too much?
Cheers
Not aware that any apps can help with quality, although there may be some that can help with Volume like Volume+ (although I'm not sure if they will affect bluetooth).
To increase sound quality I would recommend getting an Apt-X enabled bluetooth headphone/receiver (I use the HS3000 which has Apt-X, is relatively inexpensive and quite versatile since you can plug in whichever earphones/headphones you want or even connect it to speakers/stereos via a 3.5mm-3.5mm cable). The Sony one you have doesn't have Apt-X so is not able to take advantage of the S4s Apt-X capability.
[Q] Does LG G2 support Audio tunneling on kitkat? Just like Nexus 5?
Audio Tunneling to DSP
For high-performance, lower-power audio playback, Android 4.4 adds platform support for audio tunneling to a digital signal processor (DSP) in the device chipset. With tunneling, audio decoding and output effects are off-loaded to the DSP, waking the application processor less often and using less battery.
Audio tunneling can dramatically improve battery life for use-cases such as listening to music over a headset with the screen off. For example, with audio tunneling, Nexus 5 offers a total off-network audio playback time of up to 60 hours, an increase of over 50% over non-tunneled audio.
Media applications can take advantage of audio tunneling on supported devices without needing to modify code. The system applies tunneling to optimize audio playback whenever it's available on the device.

Audio tunneling requires support in the device hardware. Currently audio tunneling is available on Nexus 5 and we're working with our chipset partners to make it available on more devices as soon as possible.

I'd also like to know that.
I was just wondering if people could comment on how they are getting the best sound quality on their s5.
I generally find it sounds a bit lifeless on bluetooth in my car compared to my iPhone the same bluetooth with the same songs so i've been looking to tweak it.
From what I can tell there two popular ways to improve it.
Viper4Android ( requires SElinux mode to be set to Permissive)
Extremebeats, also needs V4A to work properly? not entirely sure it does anything different to V4A on its own?
http://forum.xda-developers.com/showthread.php?t=2634729
What I don't get is Extremebeats claims to support clear audio, SRS wow etc, but they are all different technologies, how can it use them all at once?
The V4A profiles don't seem to mention SRS wow etc at all?
What do you guys use?
