Using HTC phone as digital recorder?

Hello. I am new to the forum, so I hope this particular topic hasn't already been covered before. I did some looking and couldn't find anything.
I am looking to jump into an HTC smart phone (or a PDA phone of some kind), but the one feature I would most like to see addressed is whether the phone can also double as a digital recorder. I know there's a voice record microphone built directly into the phone itself, but I'm after something more along the lines of an external jack.
A bit of background:
I'm a writer and often find myself recording either a) in person interviews or b) telephone interviews. I am currently using a Sony MD to record both by way of a microphone that plugs in directly to the MD or a jack system that allows me to plug into a normal land-line phone. It usually works fine, but my MD is getting to be of age and is, as such, increasingly less reliable.
I don't want to record phone conversations that I'm having on my HTC itself (though that would also be beneficial), but rather as an option to simply plug into it (via a straight microphone or USB jack) and record.
Is this possible? That's the question. I've been doing a lot of research and haven't found anything conclusive and would appreciate some feedback to that end. And if not, why not? Between a smart phone's capacity to write word documents, take pictures and, hopefully, record (from phone, microphone, etc.) this would be the tool many journalists would undoubtedly want to have.

notes let one record from the mic
i'd asume that the input for wired headset mic also works with that recorder
if not then i'd guess it is bipassing the pda and goes directly into the gsm part
but i'd think it would work out of the box

headset mic and built-in mic
The question about the headset mics I have seen, though, is whether they'd pick up a telephone conversation. And then it's not a dedicated line-in, but part of a headset attachment, anyway. I just want a dedicated line in specifically for recording from an external source i.e. not any convo on the phone.

More to the point
Is there a microphone-only line in (dedicated or USB variety) available for a smart phone?

yuriy, pls read my past sound recording articles, i have answered all your questions in them

Do you have a link to those articles?
Do you have a link to those articles?

Found 'em
"Well... yes and no. Depends. Unfortunately, very few of the recent PPC PDA's (the Toshiba e series, the Asus A730/730w, the Dell x50v/x51v, the above-mentioned Fujitsu-Siemens Pocket Loox 720 and the iPAQ 5450/5550/hx4700) have a direct mike input ring in their headphones jack. Furthermore, this input is mono only - there're no PDA's with stereo sound inputs at all."
I don't really care that it's a mono jack, frankly; I am not trying to reproduce stuff as an audiophile. But which models can I plug a mike into directly to begin recording? I'm actually a little amazed that this issue has required so much digging; I would thought this would have been a natural, easy-to-understand feature included on every smart phone.

i remember in the past... i ve seen some SD card for reporters or so, with in and outs...
but my new tytn has only microSD :-(
i would be glad to have in any way line in as well... and as hell! ;-)
please keep this going here, and the big search as well...

Any word on this?

bypass headset earphone jack switch

Hi,
Before I start creating an application that would bypass the headset earphone jack switch(the one the activates once you insert a headset), I would like to know or find out first, if it is programatically possilble to bypass this manually by a registry setting or an application. If yes, kindly advice as to where I should start.

I found similar application while searching for solution to

and other HTC devices. It was writen for ETEN but
to my disapoitment doesnt work on the Titan

any takers or brave soul out there?

Hi,
As I understand it the HTC models that do have an FM Radio build in can switch the FM Radio output the the main speaker even while the headset is plugged in. It needs to be pluggen in; it's theis antenne. So my guess is that it must be possible. I myself would be very interested in such a program.
Good luck, hope you'll sucseed,
Cheers,
Cactus

yup
anybody out there who could point me in the right direction? where should i start...?

still no luck on this - pls help, even just to point us in the right direction
i've search desperately but no luck i know it is possible; first because the built fm radio application can stream through both speaker and earphone. second, i run into a bluetooth app that can divert/stream audio(not only calls). this leads me to conclude, that is it possible. i just don't have infos i need to create one. i've read many msdn articles, tutorials but still no luck that is specific.
please to all the programmers out there, help us. this is just a very simple app and it would hurt 5mins of your time just to point me in the right direction. I am most willing to view/review servelar even tons of source codes that is very similar or close to the solution we are looking for, you just have to share it to us. thank you. i hope somebody out there could help us.

In the registry:
HKLM/System/State/Hardware
change the key "Headset" 0 to 1.
but the headphones works like antenna and you dont hear any radio station.

thank you ryomahino, for taking time to reply. i'm already aware of this registry work around and have done this already, but the hardware switch still persists. aslo sometimes or when you reset, it does not persists. so the only solution is having at switch, that will run the audio both on the headset and speaker, pretty much like what the fm radio does, but must also work on calls, together with the microphone. im pretty sure this is very much simple for those experience programmers out there. if we put together that fm radio and bluetooth audio capability then this would work. just need a little push/help as to where start. or if I could look into those source codes then we are ready to go...

technical question on fm radio app
Gurus/programmers/anybody,
Does anybody know, or at the least, give me an idea, as to how the o2 xda atom build in fm radio application, programmatically (technically) toggle from stereo headset to speaker? Just even, point me to the right direction, pls, I'll read tons of infos, if need be...

Had same problem on my Raphael, here is what I did:
http://forum.xda-developers.com/showthread.php?t=444581
Maybe this or similar would help you as a workaround too.....

this app would be great for htc touch hd!
i use normal 3,5inch headphones to listen to music but when i do a call i always have to plug them out! would be nice to have an app that automatically disables headset when you are in a call so you can have your headphones attached but still talk with the phone!

Moved to Q&A section

A2DP Connect - Multiple devices

Ok, perhaps this exists already and I'm just blind to it-
I'm trying to find a way to make initiating an A2DP connection between multiple headsets easier.
No, I don't mean at the same time- My goal is perfectly rational and rather simple: I have multiple A2DP receivers (headset, home stereo receiver, 2 car stereos), and I want a simple way to connect to them from the phone.
Normally, one has to click through a staggering number of screens to accomplish this.
Start-Settings-Communication-Bluetooth, select headset, press-and-hold for context menu, hit "Use as wireless stereo". This should be a much simpler process, especially since standard feature phones can do this in a few clicks.
I thought that perhaps A2DP Toggle was the answer, since it claims to be able to toggle A2DP/Speaker from the today screen.
The problem is, A2DPToggle only supports one headset.
In other words, it only reconnects to the last device it was used with. If I just used BT Stereo in my car, when I get my wireless headphones and hit the Toggle, it will sit trying to connect to my car instead of finding my heaphones.
Eventually it will give up and timeout.
What I want is an app that is easily accessible that will either A) display a selection of previously paired headsets that the user can pick from, or B)cycle through a list of headsets, trying to find one that is nearby and on (I understand that this may prove more complicated and less reliable than option A).
That being said, is there an app that does this, or something similar, already? If not, anyone want to help me develop one?

Moved to Q&A

why don't you suggest this option to the creator of A2DP Toggle.. maybe he'll add it.

I've tried already, mentioned it a while back and got a "maybe in the future" sort of response. I posted on his thread again a couple of days ago, and started this thread in case he's still not interested.
I'm honestly pretty surprised no one else was interested in this before me- am I the only person who has more than one a2dp receiver paired with his phone???

I don't use it at all.. but I can see why someone would
as it seems nothing like this exists.. maybe you can change the thread's subject to [REQ] to request an application.. maybe another developer would like to work on this.. tho.. sometimes people demand some money for it.

[Q] Pairing Tablet as Bluetooth Receiver?

This topic is pasted all over the net and it doesn't seem to be getting much attention, however I think it should be brought to a better light.
The idea is simple: Enable your Android Phone or Tablet to become a bluetooth reciever(to replace a headset or bluetooth speakers) and broadcast audio to the device and broadcast microphone from the device.
This could be used in several different applications:
1. Using an Android Tablet as a Car Stereo Interface
(Connect Phone to Tablet Via Bluetooth and use it as a hands free speakerphone, or aux out to your stereo)
2. Multiple Android Phones
(Have a business and personal phone? Answer all your calls from one.)
3. Phone or Tablet as Bluetooth Speaker/Mic
(Skype, PS3, Xbox 360, TV, Google Voice)
I would use several of these options on a daily basis, and would most definitely pay good money for an app like this.
So my questions are:
1. Is this possible?
2. If it is, how hard would it be?
3. If it isn't that hard, why hasn't someone done it yet!?
Bump if you want this too!

Just wanted to bump this because we need to put our heads together here and get this done. I need this capability for number 1 on your list of potential uses. I also would pay good money for an app that enabled this. Phones and tablet are rooted and ready to modify whatever is needed. Ii've bumped a couple other threads today as well.

I would also pay for this!

I have been looking for this for a while. I use an old LG Eve in my car and my Captivate's Wifi connection for GPS but I would love to have it work for calls and music too.
I would pay as well.

bumping this just to say that I'm going to research the rules and process for starting a bounty. obviously the smart people we need to work on this need motivation lol
Sent from my GT-P6210 using XDA Premium HD app

Hi there,
just wanted to leave an incentive kind of post to say that I've also been looking for exactly the same thing.
My hunting on Google play just stopped after finding this post on XDA.
It's a kind of confirmation that there isn't a solution yet.
Since our rooted androids are more than capable of acting as a Bluetooth receiver, whether they may be based on new or older hardware, this seams like a very logical step in their lifecycle instead of getting forgotten in a drawer full of old and unused electronic waste.
Some doubts:
is a2dp required for this?
Is a2dp hardware related or simply a software feature?
Personally, I could live with a simple one way communication from a phone with mobile network (sender ) to the receiver. The used mic could still be the one on the sender side.
Wouldn't even need to have the receiver in a visible place as I would just connect a stereo cable from its headset output to an aux input on a hifi or a car stereo to hear music or acting as a hands-free system.
Hope this gets some real attention.
Cheers

In one year, nobody found a solution??

I can't beleive there is STILL no progress on this. Maybe I'll try asking a dev that has made similar apps the feasibility of this. There are so many practical uses for this that I cannot beleive no one has capitalized on it.

This would be a killer app if done right. Who here doesn't have an old phone laying around gathering dust? This could start off small; simply enabling the phone/tablet to be essentially a Bluetooth speaker, but then gain features and an interface using A2DP, which would evolve it into a killer way to make any car (with at least a tape deck) able to have full Bluetooth integration and control. I really hope someone can do this!

Bump

Bkb -> p -> PC (either wifi/blu/usb)
yeah so a spare bluetooth phone that connects between a keyboard and PC. Acting like a BT dongle. No way I'm spending 10 bucks for that. if an app...maybe a buck but would prefer free.

looking for this too. Wanting to turn this old phone into a bt audio receiver

Wow, endless searching and now this thread and still nothing :/ i need it for the first idea you listed, did you ever find something?

https://android.googlesource.com/pl.../java/android/bluetooth/BluetoothHeadset.java

Currently the Android Car Multimedia receives Bluetooth Stereo Audio from Phones (Andoird/Apple), how they do it?

Any news?

So many years and still nothing?

May be this is not the right way to do.

I know this is a crazy old subject but others have commented so I don't feel so bad.
I want to make my own android system for my car. I have everything I need for it (hardware/software-wise) except for this one thing.
A few years back there used to be an app called Tablet Talk, it's not exactly what we want but I'm still willing to settle for something like that. The way it works is phone->tablet->handsfree Bluetooth speaker. You could make and receive calls (including seeing the contact names/phone numbers on the tablet) from the tablet itself, then the audio/microphone goes to the handsfree device. Another added feature was when a call is happening the app stops all audio coming from the tablet until the call is done.
Like I said before, it's not perfect but at this point, I don't ever see it happening any other way. I found the app a few days ago, it doesn't exist on the app store anymore, unfortunately, I could get it to run. It just kept crashing.
If anyone knows of something then please let us know.

Years later, found just this thread: I want to do similar thing: Use a private phone (for my sake rooted with custom fw) as a hands-free bt device with an unrooted business phone (non-rooted and secure managed with company tool). I also don't want call forwarding or similar. Just do and answer calls, use phone book and call list via bluetooth like my car radio do for years.
Is there still no solution?

Question Poor Bluetooth call quality

Greetings. I am the owner of a FYT UIS 7862 device. I have now done all the workarounds regarding the poor microphone quality during a call via Bluetooth.
I have connected an external microphone and disabled the internal microphone (via adhesive tape on the two contacts).
Here is the external microphone: https://m.de.aliexpress.com/item/1005001585070997.html?gatewayAdapt=Pc2Msite
Then I reflashed the firmware with the config.txt and this content:
persist.sys.zlink.mic.vol=9.9
persist.audio.mic.senstivity=1
persist.btmic.gain=10
persist.btspk.gain=7
Nevertheless, the call quality is really extremely poor. Then I installed a recorder app and recorded my voice. The test showed a clear sound image, it really sounded very good. But as soon as you make a call via Bluetooth, the quality is very poor.
Does anyone else have an idea what I could do? Thank you guys.

I had the same issue with Mekede M300S FYT116. This extra content is not valid for this unit, flash back the original config.txt and try.

The same for me, anyone has solution on this?

IMHO : Change the microphone !!!
I think I tested about 15 microphones (recovered from various devices) until I found one that works perfectly.

I have now ordered a Sony XA-MC10. Will report on Monday whether it works. If Sony is no good, what then?

I also ordered an expensive Panasonic microphone. But, unfortunately, I was not satisfied with him; also by testing several microphones I solved the problem. The "winning" microphone is a no-name.I don't know exactly, but it could come from a mobile headset...

I connected the Sony microphone today and what can I say: it works perfectly. Now everyone can hear me clearly and understandably. By the way, I paid 25€ for the Sony XA-MC10 new (on eBay) and can highly recommend it.

I'm glad you've sorted it out. Can I make you a question about your bluetooth connection? I also have a FYT 7862 and calls occurs without problem, but regarding the bluetooth connection: does your radio connects to your phone as soon as your get inside your car or do you have to connect it manually?

For me, the smartphone connects immediately with Bluetooth of the headunit. It takes one second.
But the headunit always connects automatically to the last Bluetooth connection. If I was connected and then my wife drives the car, she has to connect manually. The same then when I drive again afterwards.

Thank you for replying. Ok, so my unit does exactly the same but it doesn´t keep "My Favorites" on the main screen, it wipes it all, through the change. Does yours keep the "favorites" of each of one connections?

Once again regarding the Bluetooth connection: I put a button on the home screen of my wife's smartphone and mine. You click this once briefly and it connects immediately with the head unit, should it not happen automatically. This saves a few annoying clicks on the smartphone. You can easily do this via Macrodroid.
Regarding the favorites: No favorites are deleted, everyone has his own. I do not have this bug.

Thanks for that tip. In fact it saves a bunch of time! I'll see with the developer why my favorites get wiped.
Macrodroid is a powerfull one.

hi, did you replace the microphone or did you also disable the internal microphone.

I have replaced the microphone. Also my head-unit had a setting in its Factory Settings an option to choose internal or external microphone. I Opted for an external one there. But even with this setting with the included microphone and one other, the other party in the call could barely understand what I was saying. Since I have installed the Sony XA-MC10, I can have a normal call. Yes, people say there is interference and noises while driving, but the call apparently is clear enough. Maybe it is worth mentioning previous two microphones were center windshield close to rear-view mirror. This one is installed on the left-side roof-support (or whatever it is called), a bit closer to me.

Same here, it's a good microphone. My unit doesn't have an internal microphone so no interference issues.
The only issue left is a bit annoying still: The other person hears an echo of its own voice, I guess my unit picks it up from the speakers and transmits it back to the other person - the echo stops once I mute the microphone.
My voice is clearly heard (unless I mute of course).
Must be software related, because the issue doesn't exist in calls using Microsoft Teams and the like (installed on the unit and using the same microphone and speakers).

Thanks for providing the solution with the sony microphone, but I wanted to ask you about the most recommended configuration of the "config.txt" file.
Did you respect the factory settings?
Or have you modified it?
