[REQ] Noise cancellation program - Touch HD Themes and Apps

While looking at headphones tonight, a question arose in my mind of whether it would be possible to get the Touch HD to monitor the surrounding noise through it's microphone, flip the phase and then "add" that to the music/video being played. That's effectively what active noise cancelling cans are doing. The HD has a microphone. It also has a headphone socket...
Does the HD support more than one audio output at once? would it be as simple as my mind thinks it is? Would the Blackstone have enough processing power to do this properly?
I can't program at all so was wondering if any of you more talented XDA-ers had thought of this!

Well, I had the same idea a couple month ago. A friends friend got onto it - some sort of "noise technician" with fancy lab and all.
Unfortunately he came to the conclusion that while it's no problem to program it, it won't be worth the time.
Why? Well, the noise that arrives at the mic of the phone is (technically) very different from the one that arrives at your ears. Noise cancellation effect would be close to zero - if not even make things worse. That's why all these noise-canceling Hardware solutions have the mic directly at the ear.
Dammit ... was pretty frustrated.

HS-12W:My preferred BT-Stereo Headset has no more warranty.

because in order to get it, I had to cut the original earbuds off...
How did I get to do this? (either read the story or jump to the end.... )
I had first tried out the Sony Ericsson HBH-DS970 and found out that it was not enough compatible with the HTC Universal (e.g.: after a call it would not continue to tranmit the music stream)
I then tried the HS-12W. All important features are supported, just ID-Tags are not transmitted nore is the name of the caller (but the number is).
On top of it it has a RDS-FM radio built-in...and looks good too...I decided I wanted to keep it.
Only problem: I could hardly understand anything....the original earbuds had a shape/size that just sat so strangely in my ear that the front was not exposed to the inner ear but rather covered so that the sound level was just too low.
Since I am one of these guys who do not give up easily when they are convinced of an idea, I was looking for a solution to the problem.
I remembered an enhancement item for the original ipod earbuds: I bought a couple of Griffin Ear Jams. I cut them in a shape to fit the Nokia buds and glued them to the rubberborder of the ear buds. Not bad at all. It was loud and had much more bass than before.
It did not maybe look supergreat with these white add ons, and frankly, the more I was listening, I found the sound to be lacking treble and somewhat sounded like from under a pillow. My personal belief is that the original earbuds are lacking treble in order to reduce the transmission of some white noise caused by the BT connection...and with the Ear Jams in place that enhanced the bass the pillow sound was perfect. It was really not bad at all, but as I said, with the time I noticed it more and more...
Before buying the Nokia, I had used Sennheiser CX-300 headphones when listening to music. An excellent value for money, it rivals easily headsets of double the price.
Now, all of a sudden. with the Nokia, I had no use for the Sennheiser anymore.... It was just laying there, on the board, getting dusty.....
should I never ever be using it anymore? Such a good pair of headphones...if only the Nokia had better earbuds...
Do you guess the rest?
Yes, i did it: I cut the original earbuds from the Nokia, freed the Sennheisers from it's cables...and transplanted them onto the Nokia HS-12W....
Yes, it worked. And it sounds just soooo good.
where did you cut it? just near to the earbuds or at the connection to the neck? (the other end of the cable)?
My problem is with the Universal + HS12W combo is that its SOOOOOO stuttering :evil: . If its on me, the Uni is in my hand, it can stutter... it can always stutter... I ask: why?? Maybe it's not because of the reception quality because at home I can move to the other room and it doesn't loose the connection just the stuttering factor rises... Is it the bandwidth or lacking CPU?
I'm starting to think about throwing it to the wall...
other con: radio sensitivity is very BAD.
I cut them somewhere in beteen the earbud and the microphone so i did not lose the speaking function. (sennheiser is only headphone).
i agree with the suttering issue. i tend to believe that it is more the pda side..bad antenna construction..but at the end who cares if it does not work...i must say the way i am using the combo i can live with the shortcomings. i also feel the stuttering increases with the transferred bitrate.
as far as the fm reception is concerned: i am not unhappy with the quality, obviously it is n ot noise free most of the time, but i get my main stations in a reasonable manner, i find. (and then most of the time i am listening to internet radio streams..i am on a 5GB plan...
cheers,
Andy.

I can agree with the bad radio construction on the uni side.. This was mentioned in an other topic too I think . It's good you have 5GB plan.. we have only 200MB for a reasonable price.
How do you control the bitrate between the devices? Does the mentioned registry setting (hklm\sw\ms\bluetooth\a2db\setting) working? I've started to play with it, but originally, this key hasn't existed.
i was thinking about the lifetime of this device, because of the battery (not replaceable)by user, and the fixed headphones... looking ath the price of that headset i don't want to throw it away after just one year..
Hi kchris,
sorry for late reply, I did not get a notification.
re. bitrate control I cannot comment. I just meant to notice that with higher bitrate e.g. different quality of radio streams, the connection is more sensitive since the buffer holds less seconds of sounds.
I only have a problem if i use the universal in the rear pocket of my pants. the body is a real obstacle for bluetooth waves, it seems. not very elegant, but it works: if you hang the display over your shoulder so it hangs down on your back, there is no stuttering if the htc is in the rear pocket....(at least in my case).
There is a screw at the back of the device...no I have not opened it yet...lol...but I would guess one can have access to the battery easily, the question is only where to get a new one from... :?
(Between you and me: gadget freek that I am, I would be surprised if I still have it in one year....but who knows...I really like it...)
Exchanging against the Sennheisers for me was a great solution, the sound has improved so much, I did not expect it, I must say.
I have to admit: I love to adapt things to my needs....
There are headsets where you can use the headphones of your choice, but I think in this case the mic must be in the device itself, so it will be quite far away from your mouth..or maybe it could have a mic on a cable that you have to clip somewhere high on the shirt..I don't know how good this is supposed to work or how convenient it can be...

Motorola S9 - White noise at higher volumes

I've just bought a pair of Motorola S9 headphones and whilst overall I'm pleased with them I have noticed one thing. At higher volumes (on the headset volume) there is audible white noise in the background. It is noticable when the transmitting device begins transmitting audio as there is a second or so before the music starts where the headphones go from absolutely silent to a faint hiss. It's also noticable on when listening to quieter songs. I've tried 3 different A2DP transmitting devices thinking they might be the cause of it but in each case the noise was present.
I wonder if other Motorola S9 owners could share whether their sets suffer the same problem?
Neil
Hi problem here
I got an S9 but I can't use it with my O2 XDA Exec. Too much skipping and stuttering. Some one told me that I would need the Broadcomm BT Stack. Which device are you using with S9. The HT820 doesn't have any of the problems u mentioned.
Ciao
I'm primarily using them with an Orange branded HTC TytN running Schap's 4.0 WM6 ROM. Compared with the original WM5 ROM that the phone came with bluetooth audio works flawlessly from both Windows Media player & HTC's Audio Manager except for the slight background noise. I must emphasize that the noise is faint and usually not noticable until you crank the volume up to a high level on the S9s. I've also tried them with a Belkin USB bluetooth dongle and the Broadcom stack and and iTech USB bluetooth dongle and the Bluesoleil v5 stack. Same result for all of them.
I'm just trying to figure out if this is usual or if I have a problem with my pair.
Thanks
Neil
Motorola S9 sweat problems?????????
Hi all, I wanted to share with all outdoor fans my bad experience with the Motorola S9.
First of all, I am a 42K Marathon runner.
Second, I can't run without music I know, I'm weird
Third, I needed a BT headset that was offered as "Sweatproof"
Before you guys to start laughing, I don't sweat oceans of salty water from my ears! I'm just the average guy...
Today, I've busted my third headset in 2 Months! (All of them gently replaced by Motorola warranty)
They gave me a refund telling me that there was no solution for the Summer season, since people sweats more than usual... (WTF)
Any other good BT headset to reccomend?
BTW, the sound quality was similar to heaven using my HTC Touch.
Thanks!
Same Problem - NOT sweatproof
I can concur, just yesterday my S9 stopped working. I can no longer turn the volume up but all other buttons work. I wouldn't recommend these to anyone as it neither works very well as a phone or a long term workout option. I was happy with the sound and how light they are so i think motorola are on to a good thing but some more "road" testing is needed.

Same problem here. I've gone through 4 of them in a month and a half. It is by far one of the worse purchases ever. It doesn't matter if it is a 2 mile run or a 20 mile run. The buttons just stop working and it takes 15 days to get a turn around replacement. Don't get the S9 if you plan on using them as they say "for active users." I've just decided to only use mine around the office. Get a different product because these are totally NOT worth it!
I was going to buy a Motorola S9 product, but after reading these review, I guess i'll keep looking for another one.
Any recommendation guys? I'm looking for a lightweight sleek BT Stereo headset mainly for listening to music on my HTC P3600 and laptop , I don't care too much about quality of sound, instead what matters to me most is being comfortable and lightweight.
Anything in mind??
Thanks in advance.

I know it's not the most glamourous option, but I wear a headband to sop up the sweat from my head so it doesn't run into the headset. I actually do sweat buckets and without the headband I quickly ruined traditional headphones.

The Desire's Radio Interferes with Head-phones?

Hi there,
I didn't believe it at first, but the GSM / 3G radio on my Desire interferes with the headphones while I listen to music, to the degree that it is, well... unlistenable. I have to activate the Airplane Mode in order to listen to music, which I think is just preposterous. I've never had that problem with any other phone.
You know that annoying noise that cellphones can induce in stereo speakers, if the speakers are connected to an unearthed socket? That's what I hear in my headphones on the Desire.
Is this due to a unique fault in just my unit, or do any more of you hear this noise?
Cheers
I hear it only when the internet connection is active - and even then it is quite low (but still there).
So all I have to do is turn off internet connection and the problem is solved.
Hi i'm glad someone else has noticed this thought it was just me
here was my thread about it:
http://forum.xda-developers.com/showthread.php?t=683024&highlight=shielding
Definitely seems like poor shielding to me. I can't believe nobody else has noticed it. Maybe because I use sound isolating headphones so it makes background noise quieter?
A very serious flaw for something I use as my main Mp3 player

Someone at your thread wrote "Apparently I had the 'only use 2G networks' option turned on! Now with 3G the issue is gone". I am actually on the countryside at the moment and unfortunately required to connect using GSM / Edge, perhaps that's what causing the noise and it will disappear on 3G? Either way, it shouldn't be there in the first place

Just under that option is the option to turn off mobile internet...try that instead, at least you still get phone calls and messages that way.
I just replied in the other topic. I have this problem withg several in.ears, and disabling internet or enabling airplane mode doesn't help at all. As long as the phone plays sound (and for four seconds afterwards - ie, as long as the "soundcard" in the phone is turned on) it makes a hissing sound, making it completely unfit for music and to some degree tv series/movies too.
edit: Guess I should mention that the volume is also too loud, there is NO way I can have it more than two or three steps from the bottom, and between the lowest step and "silence" (ie. only hissing) there is quite a jump in dB.
What product are you using? I've only noticed this on products of poor quality. Both my AKG and MW600 have no problems with it at all.
As I said in the other thread, I'm using a good quality closed headset and there is no hint of hiss.

I have the same problem with a pair of Creative Aurvana in-ears and a pair of Sennheiser CX300. While they are not the most expensive sets you can buy, they bot sound fine while used with other devices - ie. a Nokia 5800, an iPhone 3g and my old Creatove Zen Micro. It is most certapnly the Desire that is the problem.
I expect to hear noise wih low ompedance in-ears on cheap laptops and non-branded china players, but not on somathing claiming to be a great multimedia phone at a pricetag of $620 (unbranded in Norway).
This prolem most likely stems from bad intrnal isolation of the audio chip/wires/jack, and would ofc not be heard with a BT headset... As to your AKG, unless they are low impedance in-ears, whether you hear noise in them or not is equally uninteresting.
I would really like someone with a good pair of low impedance headphones and good hearing to say that their phone is NOT producing this white noise. My pal didn't think his did, but it sure does. If it is just faulty units, it means it can be fixed, so I don't have to spend a few months getting my money back and find another phone to buy.

iI contacted HTC regarding htc desire volume

I am not happy at all abuot the sound quality its too low, so I contacted them and ther reply is:
Thank you for contacting our Customer Support Center. With regards to your inquiry, Please note that we didn’t receive any problems with HTC desire volume ,however you can search over android market for a 3rd party application to raise the device’s volume Thank you once again for your continued patronage. Best regards
anyone know any apps k and r u happy with the volume , please contact theme if your not let theme know about this issu
Thanks
You aren't very clear. Is your problem the quality or the volume? And is your phone branded or not? Branded phones are sometimes limited in volume.
i am not happy about the low handsfree rear speaker volume either. the phone ear piece speaker is ok volume wise. but the handsfree speaker is pretty crap and might probably take the crown for the worst handsfree speaker on the market. i have two desire phones and both are the same. loads of similar complaints on many forums (moneysavingexpert, avforums, three blog and others). htc must be having the heads in the sand if they havent heard about it. i think it is a deliberate denial of an obvious poor handsfree speaker, htc had some chap called dave who said he was following the posts on three blog and replied about poor stocks etc so HTC is aware about this issue, they are just dishing out denials or htc tech guys need to have their ears checked ASAP.
just put anyother phone or media player next to the htc desire and play the same sound / music via all the devices and htc desire will most probably take the crown for having the poorest rear speaker. at high volumes (which one needs anyway if one wants to hear in anywhere where the background noise is present) there is a lot of treble noise. on my archos 605 if i keep half the volume, for the same clip i wont get as good a volume on my desire at full volume. it is pretty easy to miss the notifications when out and about because one didnt hear the notifications.
the poor volume is obvious while using google navigation. while tomtom 760T has a great volume, but when i use the desires speakers for navigation voice, i have to keep the music off and can get tricky in busy traffic as sometimes the volume isnt enough or is barely enough. this might not be a problem when using car stereo with bluetooth but my car stereo does not have bluetooth or an input socket in the front as it is a few years old car.
the notifications volume must be with some internal settings i canty access as i have tried adjusting everything but it does not make a difference, or much of it. but the new yahoomail app i got from the market has a much much better volume that is easily audible. for the other notifications i downloaded the 'car mode' app that makes the notifications louder by using the rear speaker, i guess otherwise it uses the earpiece speaker by default, hence the low volume for the notifications. the volume is ok when inside and when it is quiet but just not enough when out and about. i didnt have a problem with speaker volumes with any of my handsets in the last decade, i am just adding that my ears are fine as they get checked by occupational health at work!

Thanks 4 your reply
I decided to sell My phone,Its useless as a media player
No support no update Thank You HTC
I bought 2 HTC Desire phones for me & my wife. Both of them have the most lowest & weakest speakerphones I have witnessed in any phone over the last 10 years. Even the regular flip phones which are not smartphones had the good quality speakerphones for conference. It's a shame having such a Flagship phone with pathetic speakerphone.
I called HTC customer service and though I already new their scripted answer I still asked 'Is it a known issue?'. There reply was what I expected. Complete Denial. 'No, this is the first time we are hearing it.' What a joke. I told him to do some google and check the forums. I also complimented him for lying so well.
He asked me to do soft reset, hard reset and do factory reset which would wipe out all data. Simply put they were giving me a run around & wasting my time so I stopped him right there that son I have already done that.
He transferred me to their Repair department, who turned out to be Telus customer service and they said since it's a new phone you have a 1 year warranty, take your phone to the store you bought it from with the receipt and they'll replace it. I asked what if the replaced phone also have the same problem then what are my options. She said you need to discuss it with the store from where you bought it from, they can let you have another phone but you can't break the 3 year contract.
Dealing with the phones issue is frustrating enough and on top of that frustration caused by the absolute denial by HTC's customer service & not providing a solution is totally unacceptable. I'm selling my HTC Desire on ebay and probably buy the Nokia N8.
Sometimes all what a customer needs is an apology and admission that yes we are not crazy, there is a known issuee with the phone and they'll fix it. But they are following on the footsteps of Apple who literally made their customers feel like they are crazy when they reported about iphone 4 antenna issues. Shame on Apple for telling them that they are not holding the phone properly as if dealing with ignorant kids. Such behavior isn't expected from such large and reputable corporations. Nokia on the other hand makes the best phones and admit their problems and fix them.
What do expect from a tiny rear speaker?? If you want decent sound then plug in some speakers!!
Or are you the annoying twats who play music when in public?

To be fair, I also have a T-Mobile Pulse Mini as a backup phone, and the internal speaker is way, way, better than the one on the Desire.
IMHO, the Desire's speak is "ok", if you want to take/make a handsfree call whilst sitting at your desk, but is worse than useless if you are in a car - for both taking calls and satellite navigation. I do have bluetooth handsfree, so it is less of an issue for me personally, but given the price of the phone I think they could've made the internal speaker a little higher quality.
Regards,
Dave
But the phone isn't a media player in the traditional sense, you wouldn't watch a film on it without headphones...given, it could be a bit louder for the navigation side of things but I've got Sat Nav for that...

I wouldn't only because it would sound terrible from the external speaker. If it sounded better, it is something that I might well do.

The headphone volume is really low on my desire (stock t-mobile rom) even with hi end noise cancelling headphones and volume at max (am told this is a problem with the t-mobile rom), now I use mixzing which has a gain and graphic for music. It is almost imposible to watch a film while on the underground tho, which is really annoying me, am waiting to see if the froyo update fixes this, if not I will root and change to unbranded rom.

Wanted to provide my bluetooth headset recommendation for this phone

I've had pretty bad luck across the board with several bluetooth headsets I've tried through the years. Always seemed dependent on phone I was using, had to have it within like 2 feet of the phone for a solid connection...and even with solid connection voice quality was always poor, complaints on both ends. Between cell call quality never being exactly HD, adding in the poor bluetooth compression other companies were using was just too much. One in four words I wouldn't be able to understand, and between the extra noise the mic would pick up (in spite of all having "dual mics with proprietary noise cancelling algorithm!!!!111") the other person would have trouble understanding me. So I had to take care not to speak too fast, speak slowly, clearly. Far too much trouble.
This is the first headset I haven't had any of those problems with. I couldn't be happier. I regularly ask people how I sound and they say "great"; and the other line always comes through loud and clear.
I'm not sure if it's similar bluetooth stack implementation, and I haven't tested this with other phones; but with the Nexus 5 it's fantastic sound quality, noise cancelling, solid connection (even from pocket I want to say but I usually give bluetooth the 3 feet and line of sight regardless when on phone).
It's the LG HBM-235, linked below
ok I'm trying to link it but I might be spamming. Will update after more posts. You can find it on Amazon.
Hope you guys like it too!
