[Q] Tutelage on european devices? - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

On devices such as iPods there's an forced tutelage in europe, such as lower audio output.
Now my question is, does this apply to android phones, too?

Did no one hear of such forced limitations?
If i'm not mistaken the volume limit on european music devices is 100 db, where original volume in rest of the world is set at 103 db. On paper that doesn't look like much but for the human ear it's quit a lot...
If european roms of android phones have the same limitations, i'm wondering if it would be possible to swap the sound libraries from another country's rom to bypass such bs.

Play Guitar through you phone app for Android?

Hi!
This might sounds silly but do you guys know if anyone is working on something like this for android?
http://www.youtube.com/watch?v=0Nod69aTzsM
An app that makes your phone to a small guitar amp?
The iphone version has been out for a while but i cant find any info on a version for android..
The company behind iRig have been speaking about a android version but i dont think they even have started working on one yet.
It would be a really nice application! To allways be ready to record without setting up the computor and stuff like that ya know, or to just sit in the sofa with earplugs and play some sweet solos and riffs without having your gf whine about the loud music..
Found this dude trying to make something close. http://www.youtube.com/watch?v=sz-9mxWa2VA
Just checking if anyone knows anything?
Best regards and thx for all the awsomeness!

This would be awesome, I would definitely buy it. It's like a Line 6 pod but much cheaper.
I hope they're working on an android version. Android needs better quality apps.
Also, it's more of a multi-effect pedal than an amp. Just letting you know
I actually sent then a message on youtube to see if they were working on one. This is what I got.
This is the Mac/PC version. If you look at our AmpliTube iRig playlist you'll find the iPhone version. We're currently looking at the platform but do not have any versions for Android.

Yeah, multi-effect pedal.
Imageing all the fine stuff you could do with it!
You could use it as an effect to plug in to your amp. (maby quite alot of effects, if you can make your own sounds. And with new developing you never have to buy a new effect-pedal again.. ).
A strummer for electric guitar in the studio/rehearsal place.
Play with earplugs on the sofa.
and so on...
I'll buy!!
it needs dedicated hardware don't forget (about 10 seconds in on the video)
your phone only has one 3.5mm jack plug...and you need to plug a guitar into it and an amp into it too.
also, what happens if you've got your amp turned up to 11 and then you get a phone call?

These are the components you need...

These are the components you need. I've successfully plugged my guitar into my nokia and HTC EVO using this method. Now, for some software that does something cool with the input. Let me know how it works for you.

I've bookmarked that link
I am amazed that this can be done on the iPhone but not on Android.
There is another program called Ghettoamp on the market, though the devloper admits that there is still latency (he records, then processes the sound input). 20ms I think.

Why can't it be done for android? This app is really cool.

It should be possible...
Android phones definitely have the processing power to do this. The only real problem is you're input and outputs on your phone, there's really only one... the 3.5 mm jack...
But there's maybe a way around this. And I'm not an engineer or developer or genius of any kind I'm just saying what I think should be at least possible... Everyone knows AD2P Bluetooth right? You could get you're input through it.
You use the microphone of a bluetooth headset, but instead of the microphone, you get your input from you're amp/guitar/whatever... could it be as simple as soldering a headphone jack to the PCB connections on a bluetooth headset? Dunno but let's asume it's possible.
Then you connect your phone to the headset, and you've got input... Great.
The problem now is that I don't know what android does when it has a bluetooth headset AND a normal set of earphones... Does it play from both, does it by default choose, I don't know... Say you still get output from the headphones, you could easily get the output to any speakers, seems rather pointless to use the phone's loudspeaker... This part from bluetooth input to audio jack output will maybe need a modified audio driver or something...
Once you've got input into the phone and output out of the phone, you would like to have some effects and/or amplification right? That's the point isn't it? I know nothing about programming such things but maybe a few developers who do will stumble onto this thread and share their expertise...
Once again it should be possible, but for just anyone to do this it'll be very challenging, more likely and hopefully companies like Gibson or Marshall or Ibanez (their Japanese, and this seems like a Japanese thing to do) for instance will see the need for something like this, and get working on it... If they make something like that and it works well, it'll make a LOT of money... For instance after you've bought this device, they could SELL effects, to be downloaded on a sort of 'plugin-basis'. And once one company does it, all will have some variant of the concept. I know I'd buy this...
Edit: Read about the apparent latency issue that Android has... So I don't know if it's that possible just yet, maybe ICS has bettered this flaw in previous Android versions, one can only hope...
Sorry for refreshing this thread, but I'm curious if there is such app for android available right now?

You are thinking much too complicated.
The headphone jack of phones contains another pin for the microphone. A small jumper cable can be used that allows the connection of a guitar and headphones. Check out Amplitube iRig for an example.
(this type of jack is used so you can plug in a headset with microphone)
Bluetooth or something would be nice... but the latency wouldn't be, and that is exactly the problem.. Android has too much latency,
Look:
http://code.google.com/p/android/issues/detail?id=3434
Android is not capable of this because the way it handles audio is completely wrong. More recent devices have less latency but still too much. The problem lies very deep. It is a problem for game developers too. Please star this issue if you want Google to do something about it!

How about USB OTG connected to a Rocksmith USB connection?...

The Irig will work fine for this you dont need bluetooth aor usb adding yet another layer of BS to the audio streams round trip. however now that JB is out latancy is stitting around 10-12ms on adevice such as the galaxy nexus wich is completely usable (1ms of latancy = 1foot from your amp) so 12ms would be like playing 12 feet from your amp,
If you cant play like this then on stage will never work for you.
As a side note usb audio is apparently supported in JB as well now
There are now a couple of apps on Android that at least have a range of guitar effects. Delay Effects Plus (via headphone type cable) and usbEffects (USB OTG) both have an option to use Native Audio, so if you have the Galaxy Nexus running JB the latency is quite reasonable (50-70 mSec). If you have a modded ROM you may get lower latency without Native Audio option as they both read the buffer size from the OS. Of course for everyone else the latency is still an issue and varies from device to device. So to those that said they would buy .... please do!
This very issue has put me on the fence on what kind of tablet I buy. Cannot decide between note, and Ipad 3. The accessories and ItunesU has been one of the biggest attractions for me.
Litlle heads up: in their latest newsletter IK Multimedia (of Amplitube) post a few job openings, one of them being "Android App Developer"!
So they are at least working on something..

[Q] Programming a transmitter for Android phone

Hi guys, first of all I'm new at developing android app. I'd be happy and glad to have as many suggestions and advices from all of the amateurs or professionals here.
I'm currently planning to make a simple radio frequency transmitter, the one you usually find inside a car remote, and connect it to any android phone by the 35mm jack and link that to an app that I have to make as well. It's for me to have a control over my household appliances that requires radio frequency to be controlled.
What I'm asking is that how do the app link to the hardware. I'm familiar with programming language, but I think to connect it to a hardware is the challenge. How should I write a code that sends signal to that particular hardware I made ?
I know it's more to the hardware side to be concerned, but how do you guys think?

[Q] Very specific question to the hearing aid mode at european phones

Hello!
I am hard of hearing and currently use this wonderful ROM by Mateo. ROM works fine and I am very pleased with the volume of the earpiece, headset and Bluetooth :good:
Maybe can a user say something to my very specific question?
European phones usually do not have a hearing aid mode in the Call settings. Is it possible to activate this mode in the kernel itself or is this only possible in U.S. ROMs/phones ?
(The great advantage of hearing aid mode is not the increased volume but the improved inductive transmission. On my Blackberry and hearing aids in telecoil program I could theoretically also next to a running aircraft still calls easily )

[Q] Is there a root available for the Xtrons TD730a Double Din Headunit?

Hi there,
I hope I'm posting this request in the right section.
I have recently bought myself an Xtrons TD730a Double Din Head Unit, I would post a link to it but unfortunately I am unable to as the forum won't let me. You should be able to find the unit in question with the help of google though.
On the whole I've been pretty happy with the device. The main downside I have discovered though is that it appears to be running a rather cut down version of Android 4.1
It is unable to communicate with my Bluetooth OBDII device, which having read through a few of the other threads on here seems to be a common issue with many of the Android Car Headunits.
The other, more annoying issue I've noticed is that when I am streaming music from my home server over 3G, it doesn't seem to support gapless playback when changing to the next track or Audio Chaining or whatever it is known as. I use exactly the same apps and set up on my LG G3 and gapless playback works fine on that.
From what I can gather, the necessary APIs to support Audio Chaining were added in to Android API Level 16 which was introduced around the time of Android 4.1 so this Headunit should support it.
I'm wondering, if the Headunit is running a rather cutdown version of 4.1, is it possible that Audio Chaining support has somehow not been added to it's supported APIs?
Is there a way I can check if this is the case? And if so, can I get them added in somehow? I'm guessing that a good place to start would be if there is a root method available for this device?
I hope it was OK to post these questions here. Please let me know if I should have posted them elsewhere.
Cheers,
Jim

Even though its an 7 inch screen it is the same as the AN21 head unit internally. So it doesnt support obdll over bluetooth. Try getting the wifi version that it works. Try the same rooting method as that head unit.
@ little off topic question
Im sorry I do not have the information on that for you but it shocked me when you said that it didn't work with your phone over bluetooth . I was thinking about buying this model and want to make sure that the Bluetooth is able to stream my music and also make phone calls from the dash !? Is that possible with this unit ?
Another question I had is about the sound quality
The watts are not listed online so does it get loud and clear or do you need an amp with this unit
Again sorry I couldn't help ( sorry for asking a bunch if random stuff )

Thank you so much for pointing me in the right direction :good:
I've had a good read through the AN21 head unit thread. I've ended up upgrading the system software to version 2.8.3 and I've also managed to root the device.
The result is now that I am able to play my music over 3G without there being any annoying gaps between each track.
As you've mentioned, it still doesn't support OBDII over bluetooth and this does turn out to be a hardware issue rather than a software issue. In fact, the software itself does clearly support OBDII over bluetooth, it's just the hardware version of my bluetooth controller that doesn't support it.

The head unit does connect to my phone over bluetooth, I never said that it didn't. I was referring to a bluetooth OBDII adapter (for reading out diagnostic information from my car's ECU) that does not work with the head unit over bluetooth.
I've not actually attempted to make or receive any calls over bluetooth, or to stream any music via Bluetooth, but it is my understanding that the head unit does support these features.
It is probably a good idea to have a proper read through the"AN-21 U" - Unbranded 6.2" 2 DIN Pure Android 4.1 Car Stereo Radio Head Unit [ROOTED] thread available on here in the Android Development and Hacking --> Android General section as it seems as though people have had different results with regards to sound qualities depending on which software version / MCU version they are running on their unit. For what it's worth, I've left my MCU version untouched as it looked as though it was a whole different ball game to change MCU versions as apposed to simply changing the software version.
I can't remember off the top of my head what the speaker wattage outputs are, I seem to remember something around the 45X4 mark, remember those are peak ratings. I do have an amp running a sub woofer in the boot of my car but the rest of the speakers, which are just the standard speakers that were supplied with the car, are powered directly off the head unit.
I've got to be honest and say, I don't think they go as loud as they did with my previous head unit, a Sony MEX-BT3100U, so I will probably look at amping them at some point in the future, probably after replacing them with some good quality aftermarket speakers.

Anyone know if it is possible to root the Xtrons TS702L or how to upgrade it ?

How to find out what A2DP codecs are available on my devices?

Hi, I am not sure which forum to ask this question. I am on the market for a new and hopefully better set of Bluetooth speakers to replace the cheap one I have. I understand that there are a number of audio codecs used for Bluetooth stereo but not all Android sources and Speakers support the most sophisticate codecs. Some may only support the minimum subband coding. So, before I spend the money, I like to know if there is an easy way to find out (ie. via an APP on Android) if my phone and the new speaker I intend to buy have the capability to use AAC.
