Record uplink/downlink speech streams? (WaveIn, TAPI, RIL?)

Hi,
I'm trying to record both uplink and downlink speech streams of my XDA II during a phone call.
I tried many different things but couldn't get working any of them:
- I first tried the waveIn/waveOut API and thought, in the first place, that I was able to record the incoming and outgoing audio streams, mixed together. But I quickly realise that what I was recording was only the sound from the mike, and that the speech of the downlink speech was going from the speaker through the air to the mike. So I was recording my own voice (from the mike) and the voice of the other part (from the mike too as the sound was going from the speaker to the mike).
- Then I had a look to the TAPI API. I was able to answer calls but it was impossible for me to access to any of the audio streams. I think it's a limitation of the device, and that the TAPI API hasn't been fully implemented on the XDA2. But I can't be sure of that.
- Now I'm trying to use RIL, which seems to be a layer below the other APIs. I believe it might be possible to access to the audio streams, but I have no idea how.
- I also think that the audio data of both streams must be stored in the memory, somewhere in the device. But where?
Any ideas or suggestions on this? Do you think I should keep investigating RIL?
Thanks a lot
Ben

There is 3rd party software that will do this.

Re: Record uplink/downlink speech streams? (WaveIn, TAPI, RI
there is no such a program. The only thing yor program can record is the sound from microphone. This can be tested by connecting a headset to the device and trying to record anything during call. Only ugly devices like Anextek SP230 can record both sides because microphone is wired to the speaker.
You cannot use RIL or TAPI to record calls. It is a limitation of both hardware and OS. Maybe WM2005 would support this.

Yes I don't thinck there is such a program (I've been looking for such a program for the past 2 weeks). All recording softwares you can find don't do much more than using the waveIn/waveOut API and so they record only the sound from the microphone.
Mamaich: Would the Anextek SP230 allow me to record properly both sides even if I use a headset while recording? How come the microphone is wired to the speaker? Does that mean that the sound going to the speaker goes also to the microphone? Wouldn't that introduce a lot of echo in the network during phone calls?
Even if we are limited by the OS there must be a way of getting the speech, because somehow the audio data must be stored somewhere in the device (either the GSM memory or the device memory). And that's what I would like to find out.
Thanks.

Yes. I owned Rover S1 which is based on Anextek and checked this.

There is no echo during phone calls, but when using VoIP and similar programs the echo is terrible.

Call is processed by the GSM module that has its own CPU (some sort of ARM with DSP extensions). You may reverse engeneer its firmware, but it is very complex. On XDAs its OS is based on "Nucleus PLUS - Version 1.0.G1.1" by ATI. In Anextek it is Siemens MC45 module.

Well all the people that claim that Vito sound software and others record both sides of conversation on the forum are lying?
Also it seems this article must be untrue
http://asia.internet.com/news/article.php/1383691
It says that 2 way recording is possible on the xda.
excerpt: Designed for busy people on the move, the device combines a color personal digital assistant (PDA) and General Packet Radio Services (GPRS) handset into one compact unit. Among the things that the users are able to do with the unit include recording a two-way phone conversation or a 'live' conversation, listening to music, watching video clips and reading e-books.
I have now tried vito sound recorder 2005 and it doesnt allow both sides of conversation to be recorded on my xda, I took a look around and it seems the old siemens sx45 had the capability with its recorder software, here is an excerpt.
The sound recorder lets you record from the built in microphone or for ultimate fun, both sides of a phone conversation, which can be played back whilst in conversation. Confuses the hell out of folks when they hear what they’ve just said.

In a sens they are not really lying because you can record both sides of conversation, if you allow the sound from the speaker to go to the microphone. If you don't use a headset and the volume of your speaker is high enough, that will be the case. The voice of the other part will go through the air before being recorded. That's why people claim that you can record both sides of conversation even though the quality of your recording is rubbish.

With vito you get perfect reproduction of the caller but zero from yourself.

Possible to record a phone conversation?

Does anybody know if the Wizard is able to record a phone conversation (as a .wav file or simillar)?
Regards,
Henrik

I use notem on my wallaby, answer/make the call, open notem and press record. I don't see why it would work any differently on another ppc phone.
Two things...
Notem is a great little program that will record in wav or mp3.
#2. I am not aware of the laws of your country, but strongly advise that you not break any laws with my this info. It is only advice and I can't be held responsable for what you do with that info.
WHAT YOU DO IS NOT MY RESPONSABILITY!!!!
Other than that, Good Luck!

Thanks, I will give NoteM a try (as soon as my Qtec 9100 arrives).
BTW, in Denmark it is not illegal to record conversations as long as you are a part in the conversation.

If you have a Bluetooth connection on your PC and a BT headset, you could use your PC headset profile to connect to the phone ie. use the pc mic and speakers. Of course this will allow the pc to record the sound, in and out.
If that is annoying, you can then pair your headset with the PC and then it would be as if your headset is paired with your phone, the only diffirence is that the pc would be able to record the entire conversation.
This works fine for the himalaya since the himalaya itself cant record the incomming sound of a phone call. Wel, it can, but it is extreamely faint since it is the mic on the device wich records both the sound from the built in speaker and your voice.
This might be different for some of the newer devices, I dont know.

I live in Virginia, USA, and here, as long as one of the poeple in the conversation knows that it's being recorded, then it's legal too. Just curious, and I'm almost afraid to ask, but what problem are you having that this solution solves?
Good luck!

I have had one bad experience where a salesman and I made a deal on the phone.
Afterwards we disagreed about we actually had agreed on.
In this case I would have liked to have had a recording of the conversation.
But of course I'm not interested in recording each and every conversation (though it would be handy if the phone did this automatically and saved them with a timestamp etc.)

BTW, as far as one-button recording (you just press a button and it starts recording) start is concerned, you may want to check out the "One-button recording? Does it need to show the app window?" row in the article "Everything you may need to know about sound recording on the Pocket PC": http://pocketpcmag.com/blogs/menneisyys/112005SoundRecorderApps.asp
Almost all sound / audio recorder applications know this trick.

Menneisyys:
That's a nice article, but long and involved. I've bookmarked it for a long night in.
What's the short answer? What are the ways to record a phone call conversation? I receive orders and direction several times a day. This would be a fantastic option for me.
Thanks

PMRecorder is a good one.

That looks good, but how/where do you d/l it?

Anyone tried any of these progz? Because I'm afraid that they could record my voice well but have problems with recording voice of person who calls me.

I use Resco Audio Recorder and I turn on the speakerphone - that does it ok. On one or two occasions I have managed to record both sides of the conversation without speakerphone. Haven't been able to do it reliably though, so I still use speakerphone if I need to be sure.
Obviosuly you can only utilize this in a quiet place with little interference.

Don't look at "SP" prefix, it works at qtek 9100, tested.

PMRecorder records calls with a normal quality.

Anyone know how the laws are in Finland about recording a phone call?

PMRecorder does not record the person you're taking to on the wizard, just the audio going into the microphone. Here,s what their support said about it.
"The Wizard does not support the dual audio path. the HTC Tornado and Cingular 2125 both support it, but the PPC Wizard does not. Sorry about that. It is a hardware limitation on the device."

I don't know about support answers. I just record an every call with two way voices.

Your speaker is probably loud enough for some audio from it to be captured by the mic. It does not directly record the audio stream though.

You may also want to read http://www.pocketpcmag.com/blogs/index.php?blog=3&p=513&more=1 on this subject - it gives a nice overview of what you can expect from PPC PE devices and what applications there're to (even automatically) record phone calls.

tried NoteM but when I launch it, my Wizard freezes.
anyone had the same experience?

NoteM gave me all sorts of problems on my wizard. When I uninstalled it, it made my mp3 ringtones stop working entirely. Had to hard reset to get them going again.

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

Skype Bluetooth Audio Problem

Hi
I have installed skype. Audio comes through the loudspeaker, I have tried to route it to bluetooth earpiece ( jawbone prime) or at least use the front speaker.
Unfortunately no results.
I have tried audiorouter V1.0.1, BTaudio and even fring, no results, audio is still coming through speakerphone.
There an option in Bluetooth-> advanced-> play systems sounds through bluetooth but the sound ( my voice ) is distorted to the person I am calling.
Sounds like my voice has been speed up.
Any resoultion ?

Have the same issue
I have a HTC TP2 w/Plantronics Voyager PRO and the same thing I sound like a chipmunk. Skype was no help. Has Anyone figured it out?
Thanks
David

I had a similar problem, and have not found a solution, but instead I started using Skype To Go and instead of using Skype's software. it is just a regular phone call. Sound quality is much better, but it has it's limitations. I use skype almost exclusively for outgoing international calls and therefore it works for me. (it also works for me because I have a lot of unused minutes)

In-Call Recording (ICR)

Has anyone been able to get in-call recording to work on the Tmo US HD2 in full duplex using the handset, speakerphone, and/or Bluetooth headset?
Thx.
James

Nope
I'm also trying different things but so far no success (3rd party programs also don't work)

i have used acr on touch pro 2, will try it out on hd2 and report

i can confirm that auto call record works fine on hd2, records without or without confirmation. you can set it in options if you wish to save the file or not.

Image
What image are you using? Are you sure its the recording is not just echo from speaker?

Audio Notes Touch, it working on hd2
