Audio input - Java for Android App Development

Hello,
Is it possible to connect a microphone (or other audio source) simply with a cable 3.5 jack on the jack port of a smartphone (in my case a nexus 5)?
My question may be stupid, but smartphones jack port is input and output,so is it sufficient to connect a source to understand that is an input?
thank you

Usb to mini jack

Hi,
I just got an usb to mini jack cable but when i play audio it plays via the speaker and not the headphones.
is the cable not supported or do i need to change a setting somewhere
If i use the headphones that were with the phone they work.
But not my new usb to mini jack with my own headphones.
I also have a bleutooth unit but this uses mini-mini jack, and i twas supplied with a headphone inc Mic, the normal adapters for mini-mini jack to mini jack will enable the Mic all the time and can't play stereo, is there a solution for this?
I was already thinking about using tape or something
(the plug for headphones + mic is divided in 3 parts and a normal plug is divided in 2 parts)
thanks for any advise

Split Power and keep microphone/headset on jack/usb

I've got several splitters but the one thing I can't seem to find is this: split the Kaiser output between USB for power and to a female jack or usb that allows a microphone headset to be put inline. This is not the same as using a splitter that gives a 3.5mm jack with a built in microphone.
The reason is I need to power my Kaiser on the motorbike, while supplying a duplex for my helmet headset that has a microphone/earpiece built in supplied by a male jack. (I.e the male jack carries voice and sound).
thanks.

but you may need a extUSB -> 3.5mm jack or whatever type of headset you use
expansys have those 2
Ahh, that's great. You're right I will need a usb to female jack that keeps the mic/ear available.

[DIY] Sound from PC to android and PC headset to android

DIY adapter to use your PC headset in your android :cyclops:
You will need
- 2 female TRS
- 1 male TRRS
- Wires! I strongly recommend USB wires
Ok just weld everything... yes is simple. But how :silly:? Take a look in the pics.
"The original TRRS configuration was created by Nokia and has a pinout", from TIP to SLEEVE, "of Left Audio, Right Audio, Mic, Ground".
=====================
DIY adapter to pass audio from PC or other hardware to your android with male-to-male audio cable
You will need
- 2 female TRS
- 1 male TRRS
- Wires! I strongly recommend USB wires
- Male-to-male audio cable
- Soundabout
Ok just weld everything, everything except the MM and Soundabout ... yes is simple. But how :silly:? Just like the above but also look here first:
"Apple came along and in typical elitist fashion changed their pinout to", from TIP to SLEEVE, "Left Audio, Right Audio, Ground, Mic".
Then this adapter is exactly like the first above, but you will need change the Mic Right to Ground.
To force android to receive the input audio when you plug the male-to-male cable, you may use Soundabout.
Through this configuration you can send audio from any TRS output to your android, then the audio will be captured like a microphone.
=====================
The difference between both is only the MIC and GRND position in the TRRS male. They are switched. By mistake I switched and now I have 2 useful adapters.

FIRST OLD POST :
Hello knights.
My country are in such a chaos because of the manifest and I'm here mess around with technology... but I'm doing my part too xP.
Anyway, in the last days I was searching and testing a way to send the sound played in my computer, or other device, to my little android (codename Smultron).
With a 3.5mm cable (TRS or the one with 3 contacts) male to male, I plugged into the audio output of my Dell then plugged to my Mini, I started the app to record and... nothing.
Few days later, I used the app Soundabout and... nothing.
More few days later, I did the same thing BUT I don't put the cable until the end, I pulled out a bit, so the 3 contact of the cable stay full visible and... works! I was able do record the audio input of my laptop.
Also, with Soundabout, I was able to stream the audio from my computer to android calls!! For example, if you call me and I answer, if with the cable plugged I play some music on my PC the caller will clear hear what is playing in my computer.
In one more test, I used the MM cable and a splitter. With the Splitter and the cable I was able to stream audio from PC to android mic AND hear the android with a regular earphone, this test was made with a call in course, of course.
But this is only possible because in some way the PC are sending the signal with some extra power. If you try the test with a regular pc headset, without the computer this won't work.
"So why are you here if you did this you noob?" - Well I not figured out why or how the conectors are working when the stream are succesfully done. So I'm here to extend a bit this little research and ask for some help with who master this things. Also I wanna share with you all.
The keys of this are the jack conectors circuit and contacts combinations, and android audio routing using a app like Soundabout.
The main point, in other words, is how to made a DIY cable to stream audio from pc to android mic and with a splitter enable the audio output.
The reason that I'm searching for this is because initially I was looking for a way to did a DIY adapter for PC headphones with two jacks to android input, for single jack.
--
One more little thing, for the people that want to record a call without android modifications, you can plug the same male to male cable to PC MIC and start the sound record app of the Windows, for example.

I need to discover what points must be in contact with the jack input....

Look for 4-pin jack plug in google.

I was wondering if one of the rings touch the microphone pin inside the jack input and the tip won't touch anything. If the contact of an output was plugged to contact the mic input we got audio from external source to phone...
This is the average TRRS circuit in our mobiles? TRRS circuit
It sounds like you made contact with the input pin, so you might also be contacting an output pin. I'd get a headset adapter cable, so you have an input and output 3.5mm jack.

Hummm.
I found some stuff
see the second jack
I finally found something like this
and this
Electro I agree, but I don't found the adapter easily here, so this is one of the reasons of why I want do a DIY.
But you said, I will ask: someone can do the test to send audio from pc to phone through the adapter and with a M to M jack cable?
I will try to found a nice way to do it as an DIY.
I wanna know how this exactly works, If I was searching for ready solution I would be an Apple's zombie xP.
I think I found what I need, let me do something here.... thank you guys. If anyone have more to say please feel welcome.
Yeah I nailed it!
I made a DIY adapter for PC headphones to android (at least the Xperia Mini) and a DIY adapter to send audio to android trough a male-to-male cable. Soon I will post pictures.

[Q] Sound capabilities?

What capabilities does the Nook Simple Touch have for sound? I saw no 3.5mm headphone connector (unless I missed it), what about Bluetooth, or adding an headphone jack?
Thanks!
The Jorjin module in the Nook does not support Bluetooth.
There is no hardware for audio in the Nook.
You can add audio using the USB jack in host mode and an external USB audio adaptor.

Micro USB to 3.5mm Audio?

Hi all,
I'm looking for a way to use my earphones with 3.5mm audio jack via the micro USB port. Ideally, without carrying around a bulky separate amp. I bought a small micro USB to 3.5mm jack cable but it doesn't do anything straight out the box.
I don't know if i just need some sort of software to get the cable I've already bought working, or if I need some other sort of hardware.
Reason for all of this - I managed to break my 3.5mm audio output (plugged it in to a cheap ebay car audio unit and have blown something). I have wireless earphones....but just don't like them as much as my original wired ones!!!!
Hopefully someone can help me out!!
Cheers
You will NEED external DAC and AMP.
Micro usb can only output digital signal.

You need a USB DAC. There a quite a few like FiiO Q1, AudioQuest Drangonfly, Oppo HA2-SE, Chord Mojo etc. Money is the limit
By itself micro USB does not transmit sound, it transmits a digital signal, you will need an additional USB DAC
Get a quality Bluetooth receiver. Here's a great one with apt-x low latency which is crucial for video.
