Bluetooth audio correction? - Nexus 4 Q&A, Help & Troubleshooting

I recently picked up a Bt35toy for hands free call and audio streaming in my car. The audio playback is extremely bad compared to my previous audio tape converter. Does anyone have an app that can correct the sound quality for streaming audio via Bluetooth. Currently the volume is significantly lower and it sounds as if the music is being played through a tin can.
Thanks for any ideas

Not sure if it's really a problem of bluetooth streaming quality. Maybe it's a problem of power of the streaming ?
Does the "quality" of the audio playback differs from time to time ? like when you move your phone ? near the receiver ? or when it is fully charged ?
Can you (or have you) tried with another phone ?
Finally, have you tried audio/volume booster apps ? or equalizer (Viper/DSPManager/...) ?

The receiver is mounted almost directly below the phone. I have noticed a difference in distance or charge power. I will try to pay attention to that. I think a volume booster would be helpful. I will see what I can find.

I forgot about this thread. Any other ideas for increasing the Bluetooth gain?

Adjust audio gain?

Is there any software or anything to increase audio gain in these devices? I'm using the stock ROM and when I plug a cable from my car into my headphone jack on it the sound doesn't get hardly loud at all. The volume is all the way up on the Transformer and yet my iPod is a lot louder than it is. Would using bluetooth be any better? My car doesn't have bluetooth but they sell a module just didn't know if it would. :/

Thanks! I'll give it a try tomorrow. Also I don't really know much about audio but would bluetooth be any better (quality wise) than using the headphone jack, or would there be no significant difference in that respect?
I have apps called "Equalizer" and "DSPManager" and they each seem to do the trick. Is there any advantage to one or the other (including Volume+ as well) though?

How to connect nexus 4 on a car stereo using USB cable ?Is there any setting to be do

Sent from my Nexus 4 using xda app-developers app
I believe you can thru Bluetooth or an aux jack.

Not unless the car stereo supports MTP. Most only support USB mass storage which is deprecated on many Android devices now.
A2DP or headphone jack work fine.

So there is no setting inside the andriod to make it compactable with the USB cable? Or is there a work around to make it possible without a aux or Bluetooth ?
Not possible at all. I work at a car stereo shop and not a single one I have tried works. Only solution is auxilary or Bluetooth if you want to spend the extra money... Definitely worth it if you ask me though

Ok thanks for that insight. Just want to clear one more thing on it. Is there any tweaks out there for rooted devices that would make this possible?

Does the aux deliver a better sound experience compared to Bluetooth?

As far as i know there is not... USB is a pain in the ass with android and car stereos anyways. It reads the entire SD card directory and makes it a pain in the ass to navigate through your music. Go for Bluetooth man

Bluetooth quality is purer because straight data.

This actually really dissapointed me, as it was one of my favourite use-cases for my phone, not having to maintain two (or more) seperate music collections - prevents the phenomenon of heading off on a planned highly enjoyable car trip with my current favourite music, only to find that I didn't move it onto the appropriate USB device.
My last phone was an HTC Sensation running a 4.1 JB ROM, I forget which exactly, it got changed a lot . Something minimal. Anyway...
I tried using the headphone jack out, into my car stereo aux in, and even when I upped the input source level in the stereo hardware, and cranked up the volume on the Nex4, it only got to about 60% of the volume I wanted. Bah. The Bluetooth adapter for the stereo is like $200 if it's even available anymore. Very lame.
I could get a headphone amp. Actually, that's probably the easiest thing to do for me. Off I go to the web store.
Ramble over. Oh, first post here. Hi y'all. (software dev)
Thanks for the much needed insight into this issue now. Right now I have to look for Bluetooth adapter. And I hope Google will fill this gap of charging and using the music player with the same single USB cable it would be a good thing to have too.
Hi all hope you all having a fantastic day with nexus 4

Bluetooth is convenient as there is no wire, but folks claiming Bluetooth has better audio quality than line out are incorrect (sorry). You will have much better audio quality with the line out, assuming your head unit's aux input has enough gain to get to levels you normally listen to.

Yea I was wondering about that for a while. Plus Bluetooth kills the battery faster.

My Sony WX-GT80UI says that it accepts MTP.. But when my Nexus 4 is connected, it says device not compatible. How is this? Do I need to have music files on root of card or what else could make a difference?

Speaker volume increase when Bluetooth connected

Did a search but didn't find anything... I noticed that the speaker on the back of my phone plays media content much louder as soon as my Bluetooth headset connects. Anyone else can verify this?

Music from nexus 10 to my hifi

OK I would like a WiFi adapter to connect to my amp so I can play music from my nexus without having to plug it in, I noticed Logitech do one but its Bluetooth and want a WiFi one if they do them
Anyone doing this already ? What did you use ?
Thanks

The only way I have been able to do it is through Bluetooth. I bought a stereo Bluetooth adapter from monoprice.com and it works very well. I use Google music to stream.

I keep getting told that you lose sound quality using Bluetooth due to compression etc, is this right ?
Sent from my Nexus 10 using Tapatalk 4 Beta
No. Bluetooth Quality is indistinguishable from wired output, I did a lot of geeky comparison tests as am a recording engineer and believed the same as you, that BT was horrid mush. Not true!
neither could I see with analysis any difference, i couldn't hear any more importantly. From reading the actual quality is equivalent to 320/350 kbps mp3 which is CD quality with a tiny roll off above 17khz, which is **** you can't even hear if you're over 25, and there's no musical value up there I assure you. I have the Logitech one with n10 setup for my dad, all he has to do is turn BT on on the n10, it connects, then play the tunes.. all the other factors in sound quality are way more important like amp ,speakers, placement / stands, room, eq etc.

Audio issue on n9005 4.4.2

Hey all
I am running a tw 4.4.2 rom (kingdroid at the moment but had the same problem on others).
Using the stock music app or play music (a haven't tried others) when listening to music on headphones the audio will randomly be sent out of the phone speaker and headphone jack at the same time.
I have no idea why.
All I do know is I intended to use this phone instead of a dedicated audio player but I can't as randomly I scared the hell out of old people on the train.
Is this a known issue?
Any advice would be fantastic as I am so close to going and spending stupid money on a dap that I really just don't have lol.
Thanks in advance.
Scott

Update:
This occurs on all audio.
Eg.
Phone calls will route audio via ear piece and speaker. Music will play vis headphones and speaker.
All audio routes as it is meant too but in addition via the speaker.
The issue is intermittent.
No obvious trigger
