stereo to mono?? - General Questions and Answers

hello everyone,
I hava a t-mobile MDA compact iv (htc touch diamond) and listen to music through my earbuds often. Now i developed a deafness in one ear due to a benign tumor near my hearing nerve. Therefore when i listen to stereo music i can only use one earbud and thus miss out on one channel.
I cannot use a simple adapter jack-plug because my phone doesn't have a normal jack.
So here's my question. Is it possible to write a simple app that will combine both channels to a mono signal, so i can hear both in one ear?
I think more people would like it because they often only use one earbud to keep one ear free. I used to do that at work before i turned deaf on my right side.

these are the droids you are looking for

Thanks Rudegar,
Maybe i wasn't quit clear on this, my phone (like htc touch diamond) does not have a 3.5mm jack. It only has a mini-usb and needs the original headphones with a mini-usb connector. So thanks for the effort but these cables or adapters just won't help.
What i could do is use one adapter to go from mini-usb to 3.5mm jack, and then use another adapter (like the ones you just showed) to convert it to mono. But then i would either extend my phone by at least 2 inches or my cable would become a lot longer. That is a solution of course but not very practical. I have looked into these options and in my opinion an app like i asked about would be the most practical solution. So, if anyone can help. please...

it don't have a pure miniUSB converter it have extUSB
which is usb pins plus normal audio pins all extUsb -> 3.5mm converters work

Thanks again Rudegar, but i'd rather have a small app to do the trick. I think it must be possible, just don't know how. So if anybody can help.

Not sure of any specific PPC application to do what you want but instead of say having an adapter you could just batch recode your music to mono before transfer to phone many freeware apps on the market to do this.

Coreplayer allows you to play your music in mono. Go to Tools\Settings\Audio and set 'Stereo mode' to 'Mono Join'

thanx, i'll try that.

Never heard of such a thing. Nearly all cellular hands free "headsets" are 2.5mm, so I guess you really mean headphones. Just buy a 3.5mm to 2.5mm adapter for your headphones.

nearly all pda's actually use mini usb headsets(TYTN,EXCALIBUR/DASH,etc.) i was wondering if these headsets could some how be used with the 2125. I cant find a 2.5mm headset that will play through both ear buds.
you can always find one 2.5mm stereo headset (the one come with tornado works great). I myself enjoy using the 2.5mm to 3.5mm stereo headset adapter with my own boss headphone, it gives a really good quality sound. Try to get one from ebay

Um... little rusty on all the models, but not many of those are smartphones. Lots of adapters out there that do work. Unlikely any USB solution will. Not for poor little Tornado.
you guys are probably right, but i lost my headset that came with it and i want to buy another one with a mic you guys know any compatible ones?
Anything with a 2.5mm jack should be compatible. Have you considered a BT A2DP headphones/handsfree set?
I'm using a C3 from Sonorix and it's rather spiffy.
http://forum.xda-developers.com
Remote control for music, call display, comes with and takes a standard 3.5mm headphones. Mic is in the clip-on receiver. Better with those newer shorter/detachable headphones so you don't have a mile of cable dangling about.
Crushers and S9s
I use the SkullCandy Crusher ONEs as a full sized wired headset on my SP5. http://www.a2zboardshop.com/more/59603905-Skullcandy-Skull-Crusher-Headphones-with-Subwoofer/. This headset\microphone is 2.5mm four connector by default and comes with a 3.5mm three connector slip-over adapter which I find so much better than a 3.5mm female to 2.5mm male dongle when you use your phone.
For wireless, I had been using the Motoroloa S9 and could have lived with the ugle orange\red accents but the phone calls are always in single channel mono. The soon to be released S9-HD is all black and you can hear the caller in both ears.
I would be interested in any in-ear stereo headset with a 2.5mm four connector plug. Even more so if it had a a microphone.

Internal Mic with headphones

Ok having a bit of problem (a fairly common one). I've searched around and haven't found a solution. Using a cheapo headset adapter with my headphones disables the internal mic. When someone calls I want to leave my headphones in and just use the internal mic. I've looked around in the registry without much luck. Here's where it gets weird: if you plug the same headphones into the 3.5mm jack on the provided HTC adapter it works, audio out through headphones, audio-in through internal mic. For both cases the headset icon shows up in the taskbar. Also the reg key "Headset" in HKLM\System\State\Hardware\ changes from 0 to 1 in both cases. Is there a hardware, registry, or software mod I can do to get around this? I don't want to have to use the giant and bulky htc adapter.
thanks
I'm not positive but I'm going to guess that this has something to do with the fact that HTC's adapter that they gave you has additional capabilities as opposed to a normal miniUSB adapter, which is what I'm assuming you're using.
You can read the article about HTC's extUSB here:

Remote control with headphones

On my previous phones diamond and hero i've used the HTC RC E100 remote. It was quite handy, allowed me to control the music player without getting the phone out of my pocket, and the best thing was i could just use my own headphones!
Unfortunatly it has a mini-usb connector. Now that the desire uses a micro USB connector i am looking for something similiar.
Control for music, volume, phone (incl. mic) and where i can plug in my own headphones.
I just love those in ear headphones and don't want to use the ones that came with the desire.
Does anybody know about a remote that would fit my desire and my needs?
Thanks everyone!

The Desire uses a standard micro USB (5-pin micro-USB 2.0) connection, I am just thinking whether or not the Desire even supports audio through the USB...
As far as I know, the Nexus One uses a standard Micro-USB connector, which has no audio support. The only way to listen through an amp is Bluetooth or the headphone jack.

thank you for the provided information. as the nexus one and the desire are very similar, i guess the desire will miss the audio support via usb as well. in all other phones where audio via usb was supported, HTC has used a non standard usb port.
i will keep on searching for a remote that plugs in via the headphone jack. if someone has an idea
cheers,

I think I have a solution.
Jabra BT3030 bluetooth headset. A2DP and AVRCP so you get your stereo sound and also utilise audio controls. Plus it has a 3.5mm jack so you can plug in whatever headphones you want.
Google it. I've got one on the way.
I've been looking for head phones too, and these look like the best offer so far. I am a bit worried about the blue tooth running down the battery though. But let me know how you find these. If all the buttons work with the desire I'll probably get myself a set.
I've been using my Jabra BT3030 and the controls do work. There is a small time lag between pressing a button on the Jabra and it responding.
One good thing I found about the phone (with or without headphones) is that the volume control on the phone works even when the phone has gone to sleep. On my HD2 that didn't happen and it really annoyed me.

So how is the Jabra overall? Worth buying? I've been reading the amazon reviews and some issues have been raised, like the buttons not working with music after you get a call. Do the volume buttons work, and how is the sound quality? Lastly, how bad is it on the battery?
Thanks in advance.

i think i will give it a try, the only thing that worries me is the fact that i would have another thing to charge. I was also thinking about soldering a headphone jack into the standard htc remote that came with the phone. i will keep you up to date.

these look interesting, i've been thinking about looking for some headphones with music controls too...
how is the sound quality with the jabra bt3030, is it just as good as having headphones plugged into the phone?
does running bluetooth hammer the phone battery?
yea i like the look of it, the ability to skip tracks without whipping ur phone out seems great. that always annoyed me with the iphone.. but as i listen to music for hours on end at work (Without a charger handy), i wanna know how much the BT will effect battery life?
id imagine it would decline pretty quickly ?
I have a Jabra BT 3030 which I used extensively with my G1 because I hated carrying around a MiniUSB to audio jack lead.
However I haven't even tried it with my Desire, like someone said its just another thing you need to remember to charge, and as the Desire has a headphone socket (and a micro usb) it would mean carry two leads, or an adaptor to keep them both charged.
That said the Jabra has a fairly decent battery life as long as you remember to turn it off when your not using it.
The sound quality is perfectly acceptable for listening to music unless your a real audiophile, though its obviously not as good as a direct connection to the phone.

Heh. Arrowed.
I use a pair of Sony DR-BY20NX Bluetooth headphones with my desire. headphone battery life is 11hrs.it also has audio controls and can answer call.
fairly cheap but discontinued and becoming hard to find. well worth it though.

I was in CPW last week and the guy who was serving me also had a desire, he was using the Nokia Bh-214 (iirc), its a bluetooth remote with a 3.5mm plug. I tried it out and it sounded good, it has full controls including volume. Its around £40 and available
Also, I have been searching about and found the Sony MW-600 its a bluetooth remote with a 3.5 mm jack, it also comes with headphones and has a built in FM radio. Also has full controls, its around £40 and not out till May.
Personally I am going to wait till the Sony one is out, it has positive reviews and i trust Sony more when it comes to music and the like. Just annoying having to wait!
I am using a cheap BT A2DP, and it works very well. It can be used as BT handsfree or stereo earphone, also has a remote to skip and back the track, that works fine in TuneWiki (but it not for HTC player). The quality of the sound is still far below my KOSS earphone though... but for 26USD and free delivery that thing is really a good deal.
This is the link, but I just found out that is sold out at this moment.

They have another one, almost the same spec but I don't know whether it works as good as the other one.

Need help getting a perfect audio recording on my SGS4G

Im asking all you guys to help me find best methods, settings, and tweaks to get the best possible audio recordings on my SGS4G. Im asking this not only from the devs here but from all the audiophiles as well.
The reason im starting this thread is that my partners iphone 4 just with the built in mic and camera has produced video and audio recordings 10x better then what this phone has. With great dynamic quality and no distortion or anything. I need broadcast quality recordings for this project to succeed. If i am not able to do so im either going to have to try to clone the SIM card and get a used iphone 3GS just for field work, or give up this phone and switch to an iphone 4. Either of which i really dont want to do. If part of the solution is to dump GB and go back to Froyo, then so be it.
Heres what i got:
1. Highly modded SGS4G with Valhalla 1.3.2, Launcher Pro Plus
2. 32GB class 4 Sandisk card
3. UV using the settings in the ICBINB therad (i tried some lower ones dsexton posted, but they made the phone very unstable)
4. Voodoo Plus sound app
5. i-Microphone (sound was horrible, more on this later) http://www.amazon.com/o/ASIN/B004XC6KHS/ref=nosim/betteraddons-20
6. Sennheiser E835 with XLR to 3.5 mono minijack adapter
7. Rec Forge and Hi-Q MP3 recorder (trying both, if you know of any with more features please share)
First off, im concerned that the custom ROM, kernal, and UV settings may be affecting quality. Any input on this would be appreciated. Ive tried OC, but 1.2ghz was never stable and 1.3ghz drained the battery too much.
I first off was looking for a good solution for face to face interviews, i found the i-mic (link above) to have good reviews, but when i bought it and tried it out, the recordings were horrible! Like someone was rubbing their fingers over the mic when talking. I tried gain adjustments in Voodoo and the recording apps im trying out, but nothing helped.
I plugged in my new Sennheiser using a XLR to RCA cable, with a RCA to mini jack adapter. The sound is A LOT better, but still there is a humming over the recordings, and they just do not have the dynamic quality that im hearing with the iphone recordings.
Are there any equalizer and sound processing apps for commercial or professional audio work out there?
Im at a wall here, any help to these issues would be greatly appreciated. Thanks in advance.
It's hard to tell exactly without seeing your set-up but it sounds like you have the following issue.
The XLR is a balanced connector. When you go to an RCA you are dropping down to an unbalanced connector and losing your ground. That is where the hum would stem from.
To eliminate the hum you would need a cable that converts directly from your balanced XLR to a balanced T/R/S (Tip, Ring Sleeve) mini jack. This mini jack has 3 separate contact points, separated by two plastic bands on the plug instead of one.
Ideally for broadcast quality you would need to run your Sennheiser E835 into some sort of mixer with a mic preamp. Then run the line level out from the mixer to the SGS4G. Your recordings would be crystal clear at this point.
I don't believe your issue is with the SGS4G hardware. I use the camcorder with the built in mic all the time and the audio quality is fine.
Hope this helps.
you don't need a balanced connection unless you are talking about long mic cables like over 5 feet long and equipment that is plugged into AC current. Balanced connections are for getting rid of the 60 cycle AC hum, basically.
If I was trying to record using a 4g I would think about using the usb input and some kind of analog to digital converter box. Here is a cheap one -- $25 behringer UCA 202 providing 2 RCA inputs-- it's about the size of a phone. and supposed to work on linux without drivers so maybe it will work on android. I have three of them and use them for laptops. They're pretty good at eliminating noise. I just don't know if the phone has enough power to operate the unit. You need a female to female standard usb adapter to connect the data cable to the converter and something to adapt a (short) mic cable to an RCA port. if it works you can use a dynamic mic like a AKG or Shure or some smaller dynamic mic and will get better recordings than anything built into any phone. It will be a little bit bulky but you'll still be able to fit the whole thing in your pocket. I should try it with my phone and see if it works but I need to get the female to female adapter. if the phone recognizes the UCA202 it should work just fine with a Sennheiser E835. My girlfriend uses a Sennheiser MD-431 for recording songs with her laptop and one of those units.
They also have usb mic adapters at places like guitar center. If you have the female to female USB connector you can take your 4g to guitar center or wherever and try their mics out before you buy anything.
@Nazcalito....great advice, I guess spending all my time on a control room board I hear the word 'hum' and immediately think 'where's the dirty gear, who's missing a direct box.' Haven't used a cable under 10ft in as many years. I'd be very interested to know if someone could get the USB audio/phone rig cooking on or s4g, that would be sweet.

Thanks for all the responses, ive been playing around with this and i do think the hardware is the biggest issue. I noticed the issue im having is that the built in mic is not turning off when using an external one. When using the external mic, i can tap over the back mic and get the feedback from it as well as the audio from the external mic.
Now the built in 3.5mm jack is a four contact TRRS plug, the RCA to minijack adapter is only two contacts. This would explain why the little plug in mic was getting all the feedback. Though even that mini i-mic was a TRRS plug like the headset thats included with the SGS4G. Why is the built in mic not turning off?
Nazcalito, your suggestion of the USB audio interface may work, i did consider a microphone with a USB connection, though i could not find any accounts of this working by simply plugging the mic in to the phone with a USB to microUSB adapter, and didnt want to take the chance. Though i like the converter box you showed a pic of, i could just velcro it to the back of the phone to make a mobile unit. I'll probably buy one if youre able to confirm it works. Again would i have the same issue with the internal mic not turning off when using this?
One thing i ordered was something called the headset buddy, its a TRRS male plug that splits into two separate minijacks for headphone and microphone. Im hoping this will solve the problem.
http://www.amazon.com/o/ASIN/B002SK66OY/ref=nosim/betteraddons-20
Another concern is the pinout of the SGS4G. Ive found diagrams for the i9000 that shows the mic and ground contacts swapped, and others with the regular mic as the last pin that claim they are for the Galaxy S2 and SGS4G. Anyone can confirm? This might explain the internal mic staying on.
http://pinoutsguide.com/CellularPhones-P-W/samsung_galaxy_headset_pinout.shtml
http://pinoutsguide.com/HeadsetsHeadphones/samsung_i9100_headset_pinout.shtml
As well should i have all the options in Voodoo turned on for this?
Ya know, i wish i didnt order the headset buddy already, i would have tried this:

The adapter did not help, the internal mic is still staying on.
That's not good. I have a similar problem occasionally with headphones not muting the speaker when used...I have to wiggle the plug a little until it mutes. The contacts are definitely a little touchy.

Can anyone with a stock froyo SGS4G try plugging in an external mic and see if that solves it?

Headset adapter with music control?

Does anyone know where to source such a beast?
In case it's not clear, what I want is a cable with a 3.5mm jack on one end - which you plug into the phone - and a 3.5mm socket on the other end - into which you plug your own headphones. In the middle, a mic, call answer button, and music control buttons.
I would've thought such a thing would be trivial to find, but it's not. For me, anyway. No matter what I put into eBay I can't find one that says it'll work for Android / our phone - I can find ones for the iPhone, but I don't know if they'd work on the Doubleshot / Android.
Anyone? thanks! I do *not* want a full headset with its own earphones - I have much better ones of my own I want to use.
You could try searching up an aux cable + mic for cars (eg. that Griffin one)
and combine it with a 3.5mm stereo female to female adapter
I guess that would work...it'd be nice to have something a bit less cumbersome, though. Thanks for the idea though!
The video cable I use for tv-out is an iPod video cable - if that helps.
thanks, blue - the thing I'm worried about is the music controls; I don't think Android and iPhone use the same system for those. Note that Klipsch make two different versions of their s4 headset, one for iPhone and one for Android - if both used the same controls then presumably there'd be no reason to do that...
I would take a lok at the Motorola S805, its a big earmuff dj style bluetooth that has playback controls on it.
Via bluetooth I can confirm it can play, pause, volume, next track and previous track controls. It also has a 3.5mm stereo jack in case you dont want to deal with bluetooh, but I dont actually have a 3.5mm cable to test it out on.

That's probably good thinking - i'll confess I have no clue how iOS handles anything. If you find out for sure one way or the other please let us know back here.
Good luck!
Elister: yeah, bt is one obvious option - I actually have a bt adapter, and bt music controls are standardized (it's one of the official bt profiles) so you can more or less rely on them working. But the drawbacks are that bt audio reduces quality somewhat, bt link is never as reliable as a cable, and you have extra battery drain on the phone and the bt adapter's battery to charge...just more fiddling around :/
