New Widcomm Bluetooth stack brings audio and video enhancements
Broadcom Corporation announced the Widcomm BTW 4.0, a new release of its Bluetooth software, with enhanced security and adding advanced audio/video (A/V) capabilities to the industry's most widely adopted Bluetooth software. The new software was tested and qualified for native support and seamless operation with Microsoft's recently announced Service Pack 2 upgrade for the Windows XP operating system (Windows XP SP2).
Wireless, high quality stereo audio headsets and speakers enabled by the new WIDCOMM BTW (Bluetooth for Windows) 4.0 software is a new application expected to drive widespread Bluetooth adoption for consumers over the coming years. A/V enhancements built into BTW 4.0 software will bring a new level of audio quality to wireless headsets, enabling a generation of products capable of delivering CD-like stereo sound without the need for wires. The same A/V Bluetooth profile support can be expected to appear in upcoming consumer electronics products like MP3 players, cellular phones, PDAs, and other appliances.
The company sees wireless headsets or speakers enabled with this technology streaming high quality sound while also performing remote control functions such as pausing or stopping play, and selecting tracks. In addition, consumers can utilise wireless speakers, enabling enhanced sound and audio distribution for DVD and CD playback.
Broadcom's WIDCOMM BTW 4.0 incorporates the latest software "profiles," which ensure a common set of features between two Bluetooth devices. Bluetooth profiles are developed and standardized through the Bluetooth Special Interest Group (SIG). BTW 4.0 features many of the latest profiles, which provide advanced multimedia capabilities including:
GAVDP -- Generic Audio Video Distribution Profile
A2DP -- Advanced Audio Distribution Profile
AVRCP -- Audio Video Remote Control Profile
BTW 4.0 also supports the Basic Imaging Profile, which provides the ability to "push" and "pull" images wirelessly between a mobile phone or digital camera and a PC.
"BTW 4.0 answers two distinct needs in the Bluetooth space: enhanced security, and the ability to effectively stream high-quality audio to wireless headphones or speakers. It is changing the dynamics of how consumers will experience multimedia content on their PCs," said Ron Wong, Senior Product Line Manager for Broadcom's Bluetooth software products. "Broadcom's unique ability to design and deliver all the critical technology pieces for next-generation wireless electronic devices enables our partners to bring products to market quickly and with features that hold great appeal for consumer markets."
PC OEMs are already shipping Bluetooth in a large number of their commercial notebook PCs and are expecting continuous growth and accelerated adoption into 2005. With this rapid adoption, large enterprises have expressed growing concerns over security and software virus spreads. The new WIDCOMM BTW4.0 software incorporates enhanced security capability to help address these concerns
The software is currently shipping to Broadcom's early access partners.

I've long been looking for a solution to record my phone calls (for archiving for my electronic diary database - it's just fun to listen to, say, calls you've made twenty years ago. Yeah, I've archived my calls back even then - then, onto audio tapes, with my self-built automatic call recorder circuitry and automatic tape recorder controller).
As you may already know, except for some (in Europe / the States, rare, Asia-only Gigabyte models) NONE of the current Windows Mobile Pocket PC's (and only some MS Smartphone models) support this. It's just not possible to record the other party, let alone directly saving the GSM-based encoded stream to greatly preserve sound quality while keeping the same low speed (without recompressing it), just like how the vast majority of non-Windows Mobile-based call recorders do on both Symbian and in many "dumb" phones like the Sony-Ericsson t68i and the t610.
Yeah, sure, there're some software titles capable of recording conversations (most importantly, the brand new, 4.x series of Resco Audio Recorder, superseding PMRecorder, the, before the new release of the new Resco app, best phone call recorder app), but, as the restriction is hardware / OS-based, they can't lift the restriction either.
I've bought a Nokia N-Gage (got it for comparatively cheap with several original game cards - they're far better than I've previously imagined, particularly when you play multiplayer games at Nokia Arena! Highly recommended if you're into mobile phone-based multiplayer games - many titles are far better than anything else multiplayer-enabled on any other mobile platform) some days ago and played a lot with the current, compatible audio recorder solutions, most importantly, Ultimate Voice Recorder For Series 60. (The other, well-known solutions like ALON MP3 Dictaphone for S60 (2nd / 3rd), Total Recall (which, BTW, according to the homepage, will soon receive a Windows Mobile 5+ version too), LivePVR for Symbian Series-60 etc. are all Symbian S60 2nd / 3rd edition only and, therefore, don't run on the first-generation S60 OS of the N-Gage.) It worked just great (in automatic mode) and offered everything one may want to except from a decent automatic call recorder, except for the hardware-initiated beeps, which seem to be a non-fixable issue with the latest N-Gage firmware, unlike with some other Nokia models like the Nokia 6680, 6681, 6630 and N70 (and some more). (BTW, if you're interested, also see this thread on the beeping issue. Note that Beep Off can be found here for $20. Unfortunately, it doesn't have a trial version so you can't check for yourself whether it really eliminates in-call beeping during calls.)
Guys, Microsoft, hardware manufacturers, why do you want us to go for a Symbian device (or, for that matter, any "dumb" phone like the above-mentioned t610) for making phone calls? Can't you understand a LOT of people want flawless call recording capabilities? Why can't you enable this feature?
BTW, many ask whether it's legal to record phone calls at all. Please refer to this page - it's really useful. Well worth a read, particularly if you're in the United States (it lists all the states that allow for free call recording, and the ones that don't.) In Europe, to my knowledge, you're allowed to record calls in all countries without letting the other party know.
(Please do check out my already-mentioned PMRecorder article for more info on call recording issues. You may also want to explicitly check out the Windows Mobile Audio Recording Bible for alternative sound recorders. Note that, currently, I recommend the brand new, 4.x series of Resco Audio Recorder for call recording. Follow the link for a (linked series of) comparative reviews.)
Finally, I need to point out that it's the same issue that makes it impossible to implement a local voice mail / answering machine application for Windows Mobile, another highly demanded functionality. (There are several similar solutions for Symbian and Linux, where the hardware / API's allow for directly accessing and recording the incoming voice channel.) Just make a search for the words "answering machine" at XDA-Developers and HowardForums (the two most active Windows Mobile Pocket PC Phone Edition boards) and you'll see these kinds of applications are in high demand too. Also impossible to implement on Windows Mobile. Check out for example THIS ARTICLE for more info on this question.

In Germany that would be illegal. You HAVE to inform the other party. And that could lead to the situation, that nobody calls you anymore...
We had some troubles with recorded phonecalls in the past (especially eastern Germany for about 40 years... ), that would make such a product hard to sell here.
As nice as it may be to listen to past phonecalls, it would make a lot of people highly uncomfortable to know every word ist recorded.

Recording/playing sound from any analogue source is trivial with an AK4641-based
phone ( universal, hermes, athena, etc.) on the hardware level. Don't know about wince, but i've
done some tests on linux/universal and it works.
let alone directly saving the GSM-based encoded stream

It's a hardware design decision made by HTC,
and you can't override that without soldering and (most probably) heavy radio ROM patching.
The raw input/output phone sound is mono and analogue.
I wud like to add.All e-ten devices does record the calls.Also, imate PDAL, a bit of atom, Dopod P800w,D600,U1000.
All tested with Vito Audio Recorder.
We r at par with Symbian

Thanks for the info. (BTW, are you absolutely sure they directly tap into the voice stream, and make a flawless recording of the other party, even in a very noisy enviroment OR when you use a Bluetooth headset)?
you could wait for q60 t600 from gigabyte and or get the i300 which is getting also a wm6 upgrade \o/
Why I Secretary can’t mute the microphone of my xperia x1 and why the caller can’t hear my answer message
How can I fix this using registry or any tweak tool for windows mobile 6.1

TekSoft: "the MS BT stack can not be hacked to enable flawless call recording"
TekSoft, one of the most excellent newcomers to the Windows Mobile developer scene but already being Bluetooth experts (see for example their excellent BlueMouse and BlueMusic applications), have just announced in THIS thread that it's, unfortunately, not possible to "hack" the Microsoft Bluetooth implementation of Windows Mobile to "capture" speech packets and record them:
"We had another attempt of making PhoneREC possible - by intercepting the voice flowing through the BT driver when a Bluetooth headset is connected:
1) when a call is established, the software would have enabled voice routing to Bluetooth headset
2) if a headset was not present, it would have been emulated (to be able to use the device without headsets with phonerec too)
3) voice data over Bluetooth would have been in the form of SCO packets
4) our software would have intercepted the SCO packets, extract the voice data, record it to a file, and play it on the device's speaker (so no need of using the headset to hear the other party in the call)
Unfortunately this failed too, as the SCO packets are handled in the hardware, so we found no way of capturing those from a software program.
The only remaining option is to use a custom made wired headset with PhoneREC. This works and assures high fidelity sound for both parties, but the phoneREC user can only record the phone call by using the special wired headset."
This is certainly very bad news for anyone not having a call recording-capable model.
For the time being, you have only few choices if you want to record your phone conversations. These are as follows:
If you want to stay with Pocket PC's, go for either the Gigabyte gSmart. According to the user comments HERE, the O2 Atom Exec and, HERE, the Asus P525 and P535 are also call recording-enabled. Unfortunately, the availability of (some of) these models can be restricted (for example, it's pretty hard to get the gSmart in the non-Asian / Australian region and when it's available at all - through, for example, ordering via Expansys -, it is pretty expensive.)
If you prefer MS Smartphones (in the Windows Mobile 6 parlance, WM6 Standard devices) or, are ready for returning to the two-device approach (one for phone calls and basic stuff like, say, playing emulated games via SmartGear / MasterAll's emulators or quickly browsing the Web via Opera Mobile or Opera Mini, another for anything other requiring a decent Pocket PC or Smartphone), with the HTC Oxygen (HTC s310). I'm absolutely sure it DOES support call recording - it makes excellent recordings, even when a BT headset is used. Note that I have an Orange rebranded Oxygen localized to Central-Eastern Europe (I've bought mine from a Slovakian guy to keep the costs down and it has Polish / Slovakian / Hungarian localization), SPV C100. However, I don't think the original HTC Oxygen wouldn't support call recording and it's just because the given countries' allowing for call recording that my Oxygen supports it. (To make sure HTC supports it in the "basic", non-localized models, I couldn't reflash it to a generic HTC ROM discussed HERE because there are no CID unlocking solutions for the model.)
Note that some? many? other Smartphone models do NOT support call recording. One of them, unfortunately, is the HTC Vox (s710), which is by far the best Smartphone available today. It does not, I repeat, NOT support recording the other party and yes, I've tested this VERY thoroughly.
If you don't want to get the above-listed PPC / Smartphone models but is ready to keep a non-Windows Mobile phone with you, you may want to read for example THIS article on the Symbian alternatives and what call recorder applications the platform has. Note that UIQ-based Sony-Ericsson phones, according to this thread, aren't capable of recording calls, only Nokia models. Also note that it's not with ALL Nokia models that you can get rid of the constant beeping.
If Symbian isn't your favorite, you may want to stick to "dumb" phones like the (Sony-)Ericsson t610/t618 (and, probably, later models). If you assign the call recording functionality to be started by quickly pushing the joystick to the left, you can easily emulate the (missing) auto-recording functionality. Unfortunately, the t610 doesn't support saving the other party's number / name along with the recording, unlike the call recording-capable predecessors of the t610. An example of the latter are the t68(i) and the, now, seven-year-old r520m. Note that the latter only supports recording one party and the former, while it stores both the timestamp and the other party's identity, doesn't let for transferring these recordings to anything via a cabled / IR / BT connection - that is, the recordings must be played back on the t68(i). Furthermore, on the t68(i), it takes slightly more button presses to start recording (there are no auto-recording capabilities either), unlike on the successor, the t610.
Siemens' old "dumb" models (for example, the SL-45) are also stated to be able to make flawless recordings. I don't know whether it's easy to make them automatic, whether the recordings are correctly timestamped or whether the other party's number / name is also stored along with the recording.
Finally, if always switching your phone to speakerphone mode is OK with you (and your environment: co-workers / family members etc.) and you never use wired / Bluetooth headsets (which would make recordings entirely impossible), make sure you always do so. It'll deliver definitely worse recording quality than recording with a phone that does support recording, but is still better than in the non-speakerphone mode. Note that if you need automatic speakerphone activation (as opposed to the manual one), you'll want to take a closer look at VITO AudioNotes - currently, it's the only audio / call recorder application to support auto speakerphone activation (and is, in general, an excellent call recorder for both the Pocket PC and the Smartphone).
Please DO read my related articles for more information on all these questions; they may answer all your questions.
Windows Mobile device manufacturers & Microsoft, we DO need phone recording capabilities!
Review: decent phone call (!) / note / MP3 recorder VITO AudioNotes 1.3 out!
How can I record phone conversations on my Pocket PC Phone Edition device?
The more recent releases of the Bluez bluetooth stack for linux
(the one used in the Android codebase) incorporate nearly all
the full features of bluetooth:
Provided by BlueZ:
A2DP 1.2
AVRCP 1.3
DI 1.3
HDP 1.0
HID 1.0
HFP 1.5
PAN 1.0
SPP 1.1
Of most pressing interest to me right now is AVRCP or Audio/Video
Remote Control Profile. This is what is used by remote devices
controlling what is playing on our phones. Currently gingerbread
(and therefore our sensations) are using AVRCP 1.0 - this is for basic
pause/play, skip/back functionality.
The newer profile AVRCP 1.3 allows the phone to send the remote
control the track metadata as well, so your car or bluetooth headset will
show the 'Now Playing' track name instead of being annoyingly blank or
just saying 'bluetooth'.
So as this blankness has started to really annoy me I am
desperate to know if there are any kernels or Roms where people
have integrated the new Bluez stack (or just have AVRCP 1.3
enabled)?
If there are no existing roms, are there any projects to develop
this for the sensation?
Restoring some functionality that was present in my old nokia
phones (smart & dumb), even in the old WinMo HD2 and most
annoyingly - the iPhone, would hopefully benefit all users of the
sensation.
I noticed that the new Motorola RAZR actually supports AVRCP 1.4,
so is there any way to port that back to us?
Thanks
Bump! I am also interested to know if anything is being developed / updated for the Sensation's BT stack.
Also curious about this as well. I've got a rooted Vizio vtab1008 with Gingerbread, and development on that platform is pretty quiet. The Bluetooth stack it has is terrible (although not nearly as bad as the one on my LG Ally) - it simply can't keep its bearings about itself when trying to use a Motorola Bluetooth stereo headset. Audio skips and stutters annoyingly much of the time (rare to get a "clean" session), and almost completely loses its mind if the device goes to sleep and wakes up while the headset is connected - the connection integrity breaks down so bad it often disconnects itself completely or locks up the Bluetooth stack.
So... that said...
I was interested in finding a way to make this work, if it hasn't yet already been done or proven impossible. Not intimately familiar with the Linux platform inside-and-out, but I've gotten pretty good at it (*almost* had a working build environment compiled on the device itself once - just forgot about it). First thing I can think might be a barrier is if the updated version needs to have all the app-interface core libraries or interfaces to be recompiled under the new BlueZ version's libraries - which may be a PITA, though if I understand the architecture correctly, there's only a handful of higher layers in the stack that would be "touching" BlueZ and be affected. Or am I way off? :/
bump ....
this would be sooo awesome
just buyed an sony ericson mw600 an get the the title information shown up with the CM7 ROM.
Only works with the stock player, but it has AVRCP 1.3
Bump!
AVRCP is ROM reliant? or music player?
Cause I would like to use BT audio streaming between my Sensation (ARHD6.6.3 with faux123 6b5) and my car kit (VW).
Thanks!
I have an HTC Sensation 4G on TMOUS, and I am looking for the same solution here. I am rooted with a stock rom, latest ICS.
Does anyone know how to get AVRCP 1.3 on my phone, or a ROM that supports that profile?
Also, does anyone know if JB will support this newer profile?
Thanks!
bump
For those of you not familiar with Rogue Amoeba they are the developers of a very popular iOS/OS X and now Windows application called Airfoil that is capable of streaming any audio source to any Airplay capable device or any device with their "Airspeaker" app installed on it.
As you can imagine they have had great success with this app. Unfortunately they have no plans to develop a version for android. This was made clear in a post in February located here:
rogueamoeba.com/utm/2012/02/18/sending-any-audio-to-android-devices-via-airplay-with-airfoil/
I also contacted Paul Kafasis (CEO of RA) and his response was the same explaining further that Android actively prevents access to it's audio making it nearly impossible to develop an app for android. I've included our conversation below as well.
ME:
I would like to officially submit my request to have the Airfoil app developed for Android.
With over 300,000,0000 android devices sold worldwide as of February 2012 (over 10 times the amount of iOS devices despite a 16 month head start) and another 850,0000 activated every day the potential here is absolutely enormous.
Please seriously reconsider your decision to not develop for android at this time.
PAUL:
Hi Drew,
It's an interesting idea, but at this time, I'm afraid we have no plans for Airfoil for Android. While Android allows for more access than iOS, it's still nearly impossible to grab another application's audio to send it out. As such, Airfoil for Android is a difficult proposition at best.
Perhaps more likely is an Airfoil Speakers client for Android, enabling you to *receive* audio on Android. We don't have any announced plans for that either, but it's likely what you'd see first, before an Airfoil for Android.
Anyhow, we'll keep our eye on the platform, and see what happens!
ME:
Paul,
Thanks for the quick response. I am not a programmer so I won't pretend to know the complexities involved with grabbing the audio output of the device and redirecting it but I wouldn't think it would be extremely difficult to redirect all audio on the device no different than when you plug in a set of headphones or send your audio over Bluetooth. This is what I believe to be the primary feature of your software. Being able to set each app individually to use airplay as a receiver would be nice but certainly not necessary for initial releases. I would hate to see someone beat you to it since you've done such a great job on your iOS, OS X and Windows applications.
PAUL:
Drew,
You wouldn't think so, no, but it is. Android simply does not make this functionality possible, and actively prevents it.
Anyway,
Where I'm getting with all this is that a lot of people would like to see an app with this capability developed for android. Especially now that a large number of devices (receivers, speakers, etc.) in recent years have started to come with airplay compatibility out of the box. People have been requesting this from Airfoil for over 2 years with no response. I was hoping to get the following answered from someone with an intimate knowledge of the capabilities of android:
1. Is it possible to develop an app that is capable of routing all audio on an android device to an Airplay device?
2. If not possible on a locked device, is it possible on a unlocked/rooted device?
3. Is this something anyone on here would be capable or interested in developing?
Thanks for all the help.
Anyone have any opinion or feedback on this? Is it possible is it not?

I would LOVE to see an app like that! My whole house is wired for airplay with 6 zones and speakers in all ceilings. Iphones can play music in any room. Only app for Android is Honey Player and that is terribly buggy
It would be awesome if it was just possible to send ALL audio like bluetooth A2DP !!!
I just wanted to add my desire for such an app as well. I have airfoil all set up so I can stream from my laptop to my HTPC but it would be awesome if I could do it from my Android phone and tablet.
There must be a developer on here that could do such a thing and I for one would be willing to donate.
The last thing i want is to propagate the Apple jail cell.. they are the only kid on the block that does not want to play with others... and yes, i own an iPad.
I USED to want to get airplay running in my house but i realised that my Samsung Galaxy Note, Blackberry BB9930, Dell PC, HP desktop, HP laptop, Gateway Netbook and Sony TV ALL support DLNA and so i have stopped caring about my iPad and its audio...
A DLNA app for Ios and an itunes plug-in would be the way to get universality here

DLNA is fine for streaming media files from one device to another but it is not capable of streaming media from a streaming service. I.e. streaming Google music or Tune In via airplay to your home stereo. Really the only solution to date is airplay or bluetooth and bluetooth just doesn't have the range. AM I missing some other solution?
iMediaShare has Airplay capabilities, I use it to stream to my AppleTV(s).
iMediaShare is not compatible with Airport Express at the moment...I tool would be willing to pay for an "Airfoil for android" type application the key being that it can send ANY audio source to the Airport Express.
Plus 1!
I am still looking for this! My apple days are over, but I still own 3 Airport Express devices and 1 appleTV.
JB has ability to do USB audio. Are we getting any closer to "airfoil-like" app for android. I too have 4 zones set up in whole house audio, and hate my first gen ipad these days. Whoever makes this app will make some serious money on the market.
Any news regarding this...?
Seriously... this would be a gold mine for the developer. There are so many Airplay speakers out there that would make playing music to your speakers so much easier.
Isn't it possible to root your device and send all sound output directly to an airplay device?
Sincerely
L
Airplay for Android? I think i'll try that!
i'll attempt this. If i start now, i think i can have a beta version out by february. I'll keep updated for links and progress.

It may be a bit late now that miracast has been established and is starting to go into devices. It pretty much does the same thing as airplay except a little better. However it's still brand new so there aren't many devices that support it yet.

While I agree that Miracast duplicates some of the features of AirPlay, that doesn't change the fact that many people already have AirPlay devices (eg AirPort Express) and don't want to buy new hardware if/when it's available.
I would love a "Airfoil for Android"-type app.
However, as a workaround, does this sound like something feasible?
1. Connect Android device to PC via Bluetooth.
2. Setup PC as a Bluetooth speaker for the Android device. (Is this possible?)
3. Use Airfoil to route audio: Android > Bluetooth > PC > Airfoil > AirPort Express (I've never used Airfoil, so I don't know if this is possible.)
Just wanted to add my support for something like this. I would gladly pay money for this app. I have a Galaxy S2 skyrocket and a Nexus 7. I would love to be able to use my nexus 7 as an audio receiver and stream music from my phone (Play Music / Pandora / Songza / etc) to it. I realize I could set up these apps on the n7 itself and play directly that way, but the key is having the ability to control the music from my phone. Additionally, my friends who have Android phones and the app should be able to do the same with relative ease.
Currently I have AirFoil on my laptop and Android HiFi installed on my n7 and stream music that way. That is less than ideal. I don't understand why this is so difficult? But then again, I'm not a programmer.

I guess that works. I feel like it's kind of overkill and it sucks that you'd have to daisy-chain using both bluetooth and a laptop/desktop. But in the absence of anything else, we have to make due, right?
Airfoil can't intercept audio from the bluetooth stack server, I've tried.
I am also interested in such app

We all are. It is shocking nothing has come of this.
It is indeed shocking. I'm guessing there's not a lot of work being done because it is too difficult (though I don't quite understand why that is). I am hoping Google blesses us with miracast in the next release.
