Wireless microphone - JAM, MDA Compact, S100 General

Like most of us probably know, Ateksoft released that Coolcamera program a while ago, which makes it possible to use your very own ppc/pda/mda/whatever as a webcam for your computer. It might not work great and the bluetooth connection isn't really good for the image quality either, but it does deliver 2-5 frames per second which is more than msn can even send through.
If it is possible to push streaming video through the Activesync profile, then an audio profile should be possible, no? As in, the ppc recording audio, encoding it into mp3 and then streaming it to the pc. I've never seen it for real before, I'm just asking if any of you has ever seen it before/considered it before.
I can't code to save my life, so that option is cancelled out.

bluetooth audio from pc to phone

I want to know if it is possible to forward all Pc audio over bluetooth to the phone?
Basically I want to use the phone as a wireless audio link so I can walk around the house with access to my music on the pc. Also in the future, may want to set up the carpc in the same way.
Any info on this? The forum/google search picks up phone->other devices... never pc->phone.
Thanks
"to walk around the house...."
This may not be possible... unless I've gotten hold of completely the wrong end of the stick (which I hope I have), the range of the bluetooth on the pda is EXTREMELY short.. I understand that when streaming to bt headphones people are happy about getting a 50 cm range.
EDIT... actually the bluetooth on the BA is supposed to be a class 2 device which according to specs is supposed to have a 5-10 m range... so I ammend my above statement by saying I'm not really sure.
Can someone confirm either way please.
Thx.
Pardon me, my 'house' is a 1 bedroom tiny apt. A 5-10 m range would more than suffice.
I've heard of bluetooth wireless headphones from logitech... these have a 33 ft range

As long as it's line of sight you should have no problems at all.. as for the range of the headphones.. it all comes down to the range of the pda.. which isn't very good. It turns out that the range of a bt network is better.. so the problem seems to lie with the audio gateway stacks. (which is a big problem)
I don't think you'll be able to do it without a lot of work, (or maybe some 3rd party software) The first approach would be to use the bluetooth headset profile. But neither your phone or your pc has a headset profile. They proably both have audio gateways that can "support bluetooth headset profile" That is, they both want to play the role of the computer, and neither can play the role of the headset. Also, the audio would be narrow band and mono so it wouldn't sound that great.
You would want to have the advance audio distribution bluetooth profile. In order for it to work, one device would have to be the audio source and the other the audio sink. I suspect that neither supports this profile, but perhaps they do. Some newer phones do support it, and many usb dongles for PC's come with profile drivers, but even if you have both I suspect that both will be set up to to be the audio source. (windows before XP service pack 1 didn't support bluetooth at all)

Thanks I was worried about that... It doesn't seem that anyone has thought of this way of using BT and I doubt that there is software to do it out there. I may fiddle around with it later on... but maybe one of those bt headsets would be just fine!

Maybe it is not the solution you are looking for, but why don't you consider using WiFi instead. It's easier to configure, better sound quality, and you can setup as Ad-Hoc if you do not use WiFi AP.
I am doing this in the house and the media pc in my car. It works out just great.
Thanks I'm looking into it...
Any recommendations on cheap but good wifi cards?
Any wifi card from Circuit City / Best Buy will do. All you do is set up an ad-hoc network, install Orb to your PC and you'll be able to browse your media collection on your phone while you walk around. If you're just gonna be in your house/apartment and wanna stream music to your stereo bluetooth headphones, you could just pick up the Motorola DC800 which I've been raving about since day one. I can stream music from my laptop to my headphones and it sounds great no matter what floor of my house I'm in.. the only downside is that I have to create a playlist before I leave my laptop because you can't control what you listen to from the headphones unless you use your phone and Pocket Player with the WM plugin. Hope that helps!
the closest solution i can find

Update on 2007 Sep 8: added test result for Windows Media Encoder 9.

Old laptop = a2dp reciever for PPC stereo?

This may be off topic for the forum, but I'm wondering if I could throw some ideas around in the hopes that perhaps someone from here has done something similar and could offer suggestions.
I've got this old IBM thinkpad attached to my stereo system which I use as a streaming media computer for my music (obsolete laptop, but good for playing internet streams or media files on my home network over the stereo).
I very often attach my pocket pc (HTC Titan) as my music player to the stereo as well, usually using a portable a2dp receiver with a 3.5" port (i.tech r35, to be exact) to stream music wirelessly.
Problem with this is that I constantly need to charge the r35 adapter because it won't charge the battery while playing music (poor design choice).
The obvious solution, since my laptop is always hooked up anyway, would be to add a bluetooth dongle to the laptop and use it at a receiver.
I tried this, but sadly WinXP does not support the A2DP profile in its native stack, and I don't have a valid license for any of the third party ones (broadcomm, Bluesoleil, etc).
Is there a simple way to support a2dp stream receiving from this laptop? An open-source bluetooth stack perhaps?
The truth is, I don't really need *windows* on there for what I use it for, I would be open to installing a linux distro if it had a2dp support built in (and wasn't too complicated to install and use... I've got very limited linux experience).
What do you guys think?
nobody has any pointers?
Wouldnt it be easier to do via wifi? Better range and higher quality than A2DP too?
i've used my wizard to stream to my laptop before with just the native bluetooth stack on the laptop
i'm sure you could just buy a bluetooth dongle and sync it via A2DP that way
Download bluesoleil, it has an A2DP server you can use to send audio from PPC to the laptop.

Um... I'm not sure that you understood the concept here. First of all, when properly configured, a2dp is virtually indistinguishable to wired speakers when dealing with mp3 files (you lose a slight amount since it IS compressing the data, but not any more than a well encoded mp3). Second, range isn't an issue since I plan to control the music from the room I'm in (why would u want to play the music in a room far enough away that u can't hear it?).
Third, unless I haven't heard of a new Wifi audio protocol, I think what you're talking about is TOTALLY different. I stream music to my stereo from networked computers all the time, but thats not what I'm talking about here.
I use my ppc as my personal music player, and sometimes I want my playlist on the ppc to come out of the stereo system in my house. A2dp lets u do that by simply BEING IN THE SAME ROOM AS IT. I frankly don't see how WiFi would be an acceptable alternative to this since there is no audio transport support built in- its designed mostly for just networking.
I'd love to be proved wrong, so please share with me if I'm missing something here, but how would Wifi be better?
thenext1, I actually have bluesoleil, but its not registered to my device so its stuck on a 5mb trial version (5mb of info and it stops). I was thinking of something free / open source, which is why I thought about a linux option. if there is a free windows stack for A2dp, I'd love to try it...
This looks intersting I am about to try this bluesolei
What I'm looking to do is actually route calls to my laptop mic and speakers when my phone is docked in the cradle...
I'm thinking since this is the same principle that it can be accomplished?
Let me know if anyone has done this before...
it is kind of "off-topic" but i think it was relavent to post here because it deals with the same principles

It's not the same principle, A2DP is for hi-quality audio, you are trying to make the handsfree profile work.... It should work, since bluesoleil can also do that

Wow. You have got some aggression issues.
First of all, read through the entire post above and replace A2DP with WiFi and see what comes out. There is no advantage of using A2DP over Wifi if you have wifi on your phone. Set up a simple streaming server on your mobile then stream it over Wifi to your laptop. After the first configuration you run one application on your phone and press play in whichever media player you have on your laptop to start the music. Dead easy. Full quality, no reencoding or anything. Control the music from your PDA etc etc.
Not entirely sure what you are on about with the range? Wifi works perfectly if you're in the same room, what's A2DPs advantage? You dont have to stand 100 m from your stereo just because you're using wifi
Oh, and reencoded A2DP is _not_ indistinguishable from MP3s on normal speakers. Unless you mean laptop speakers. A2DP is a lossy encoding that is limited by the connection speed (and thus signal strength) which means that you have to be right next to the bluetooth receiver to get maximum quality. As you move away from the receiver the signal will drop, thus the speed will drop along with sound quality. Same thing happens with Wifi but the lowest connection speed over Wifi is still way beyond what you need to stream music at decent quality.
And.. ehm.. Both wifi and bluetooth are ways to transfer data, A2DP is just a protocol like FTP or HTTP. No magic there, Bluetooth and Wifi are basically the same thing but with different bandwidth and range capacities. In this case you'd use HTTP to transfer the music over Wifi instead of A2DP over Bluetooth, result is the same.
why isn't it the same principle?
my motorols HT820 headphones are A2DP and it has a microphone on them and i use it as a headset and to play music
...
BTW if you're looking for something free and linuxy why not use VLC over wifi
i'm almost positive they have a mobile client and it would def. be better than a2dp
I have to say I share the thread starter's frustration on this. Perhaps a little clarification is in order.
A2DP is far better suited to the purpose than a stream server on wifi in this case, because was simply designed to do exactly what Dishe is trying to do - connect an audio source to an audio sink without wires. Given the right software stack, all this should involve is a quick pairing procedure.
Streaming audio on the other hand, especially from a mobile device, is somewhat tedious - hacky at best, but certainly not "dead simple". You'd have to set up a stream server, probably third party and definitely not part of standard wifi installs. A audio streaming server on a mobile device could prove to be quite a resource hog as well. Attempting to this so in a time where bluetooth dongles (especially the made in china ones) that come with Bluesoleil go for next to nothing sounds like unnecessary fuss to me.
About a solution, I think picking up a cheap bluetooth dongle with Bluesoleil installed would be the most painless way to go. Linux and bluetooth don't exactly play nice from experience, but I've never actually tried to run an A2DP sink on it. You could do some reading on BlueZ, which is linux's standard stack and see if anyone else has had any luck.
Right now, A2DP sources are more common on PC stacks than A2DP sinks - people usually want to send audio out to a wireless headset or something instead of recieve audio - so google doesn't seem to be of much help. I'm currently trying to get it to work as well, and will test BlueSoleil within the week or so on a Windows computer and post back here if it works. Don't hold your breath, though.

Record a phone call

I've tried VITO Audio Notes and Resco Audio Recorder and neither of these seem to record the other half a phone call. I'd like to be prepared and have something which can record a call if need be, but nothing seems to work. I've read that this can be down to hardware. Has anyone managed to get anything like this working on the Xperia X1?
Thanks
this thread make me remember, I swear there was an in built call record function back there when this phone was previewed, where is it now?
it waz the providers callable mailbox. LOL
dialed by shortcut
i wish this feature, too. long time ago,.... but no htc device can record a live phone call.
but i hope, that a bluetooth wrapper will come in future. (to redirect audio streams. if the bluetooth driver can capture and send audio streams over air, a fake driver could handle like the bt driver. but without bt-hardware-chip is activated, to save power consumption. the recording app commincates with the wrapper/fake driver as BT-protokoll (fake headset device))
try to use the buildin notes application to record, it may help

Bluetooth headphones with no delay for movies

Hello,i want to change my wired earphones to wireless ones, so ive been searching for a bluetooth headphone that would be good not only to listen music but also good at watching movies and i couldnt find any that dosnt have few secs off delay . So anyone knows any bluetooth headphones without the delay?
I've got some dell BH200 bluetooth headphones. They work great; no delay at all.
LOL delay! a Few seconds! Who the hell would buy them?
I been using the much whined about S9(9) motorolla stereo bluetooth headset for almost a year. Got a call in to radio shack now to replace them, (volume is all that dont work- dont leave them in your glove box in 140 degree heat lolz!!)
Ive never experienced any sort of (noticeable) delay with my bluetooth, i use them for everything. Movies of all different formats even.
Im not sure if your implying that after reading the specs you think theres seconds worth the delay, or youve personally experienced it. But This kid never has.
We're talking milli-seconds not full seconds.
Do it the right way like i did, and turn in your 120 dollar receipt at work.

A2DP is designed to have no delay, so no A2DP set should have one... I have one set of BT headphones, an adapter plugged on my hifi set, and a 3rd one on portable speakers, and none have a delay. I'm also using A2DP between my laptop and desktop PC (so that the sound of the laptop goes out on the 5.1 set connected to the desktop) and there's no delay either.
So if you did experience delay, you must have stumbled upon THE rare crappy model.
Did you check the video for delay?

Some video if not properly encoded the audio will be out of sync and will get worse as it progresses into the video. You should compare the same video with the wired and wireless to verify the delay.

Fring video calling between HTC EVO 4G and Nexus One (youtube videos)

I uploaded two videos of the Fring's video test calls between HTC EVO 4G and Nexus One (both phones connected to 3G). I was really impressed with the video quality (not so much the picture quality, but the very small delay in transmitting the video). On the other hand, Fring's audio is not so good imhoa nd needs to improve.
EVO's front facing camera and kick stand make the video calling extremely easy and convinient.

I had a quick test of the Fring’s audio by making audio-only call between Skype on the laptop (built-in mic and speakers) with Android Fring app running on Nexus One (no headset). The delay was noticeable and a bit irritating and the sound was quite distorted. Headsets would help a bit for sure and I will do few audio tests with headsets on both sides. But from the way the sound was coming through, the audio appeared to be over-compressed (as compared to an excellent audio quality of Skype’s PC-to-PC audio calls).
why does the announcer look like an oompa loompa? is it just distortion from the camera looking at a monitor or TV?
Some distortion, but not that kind of a distortion .
Feel free to suggest any other funny videos to test video calling on.

I did few more tests of the fring audio with and without video. Audio quality didn't seem to depend on whether video was on. Headsets on both sides helped as expected. I guess I would call the audio quality acceptable/average. Still way more distorted than PC skype-to-PC skype, but I guess we need to cut some slack to mobile voip calling, since it's going over 3G. It's for sure usable both for audio and video calling. The added bonus is that fring easily accesess skype's contact list.
Two tests were:
1) Nexus One (headset) connected to EVO 4G (headphones)
2) Nexus One (headset) connected to Thinkpad laptop (headphones)
Phones connected over 3G.
The first test actually had a better sound quality (since EVO 4G probably has a better mic than thinkpad).
Did more extensive testing of fring’s video/audio calling and my impressions remained roughly the same: very reliable video transmission, but audio needs improvement. Did a number of calls from Android Fring over 3G to skype running on PC (DSL). Headsets on both sides, cameras on both sides.
- Skype contacts integration is really good.
- Didn’t have any problems with the video.
- Audio is quite distorted (as compared to skype or regular cellphone).
- Occasionally some horrible loud noises interrupt the audio (once every 5-10 mins).
- Audio delay is about 2-3 seconds.
- With the video off, audio quality doesn’t improve.
