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

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

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.

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.
Hi,
I used to use a Symbian App on my E71 called Total Recall - Recorder. It recorded all incoming/outgoing calls and then sent them via FTP or email for storage.
I cannot find anything similar that works well for WinMo. Does anyone know of such an app?
Just had an email from Killer Mobile Software who make TRR and they said they are currently woking on a WinMo version
Resco Audio Recorder, ACR 1.2.1 (search forum) and many more... But NOW possible only 1-way recording (mic + speaker echo). I wait for solution for 2-way recording
read this http://forum.xda-developers.com/showthread.php?p=4973398#post4973398
Well it's here now since march I think. But it doesn't seem to work on my HD2. Killer Mobile has a trial available on their site. When I install that, and try to start the app, the screen goes gray for a moment and then the app shuts down to my home screen ..
currently none of the recorders work as you expect them to, because htc changed how the audio is routed. they only record the other person when loudspeaker is active. you can sometimes make out the other person when it isn't activated, but that is the earpiece noise carrying through the phone to the mic.
i use audio notes touch, and just remember to activate loudspeaker for ones i wanna save.
Hello everyone,
I am going to buy HTC HD2 from O2 soon. I've just spent a couple of
minutes in the shop playing with the phone and it's great.
The only thing keeping me away from buying it is the lack of call recording
application. I need to record my incoming and outgoing calls.
So, my question is: Have you come across any application to record the calls
if not, is anything like that in the pipeline?
Thanks,
Laurentius26 ROMS have Automatic Call recording, application which record phone calls automatically and after the call, ask you if you want to save them or not... it is call ACR... I have not managed to find the application that same application that works on the HD2 outside Lau's rom... maybe if we ask him?....
Anyway, yes there is an application..

this version..well
"Devices that only work one way
Touch HD2
HTC XDA2
Xperia X1"
Apparently ACR suffers from very low caller volume and I've just tried Audio Notes Touch v1.03 and its the same.. really would be nice to find a fully working set of software that will work on our HD2's..
Hi Terry,
I ve noticed you are with O2. Did you have any problem
using ANT 1.3 in the UK, as it says its "These applications are not legal in all countries".
You said:"suffers from very low caller volume", cld u tell me more pls.
Can you hear the conversation well when re-listen? (does it help if u plug your headphones in to re-listen?)
Is there any noise in the background? Is it enough clear to understand the talk?
I am not a native speaker thats why I am asking about the details.
Thanks
This works on some depending how the mic is wired.

To be honest I did forget to mention one important thing which is I always use a bluetooth headset which may well have an effect so I'll have to try it again without it..
With the bluetooth it records my voice perfectly but the caller can hardly be heard as they are very quiet...(this is by playing it back with bluetooth switched off and listening to the phones speaker..if I playback a recording while still connected to bluetooth I hear nothing at all!) Sorry but I dont use plug in headphones of any sort at all as I don't like getting tangled up in wires
There is no problem with background hiss or static but you would need to be somewhere really quiet to be able to hear the recorded callers voice (in fact on my second test call,I couldn't hear it at all) no need to applogise for your language..this is the only one I know so it's me who should be blushing from ignorance.
Now going to try again but without bluetooth...
Well,if you use the phone without bluetooth it seems to work perfectly...my voice was crystal clear and the other voice was as clear as it was when I was speaking to them (obviously if you have poor reception due to your connection, quality of the recorded voice will be at the same level)
I've also just found some other recorders that I'm going to test out ,when I can, to see if any of them offer bluetooth support!
i would like to know what is the best call recorder (automatic) for xperia arc....
that record two voices withot handsfree on..
thank you
I'm in need of this software too, but unfortunately, for now, there's no software that works right! I've tried Ultimate Call Recorder, Call Recorder, CallRecord, Killer Mobile Call Record... And just one of those are work: It's CallRecorder. But it's not good, the sound of your side is loud but on the other side, it's too low that you're hardly hear anything!
When I was in X10 with 2.1, Ultimate Call Recorder does the job well (though it's still uncomparable with Symbian about loud and clear, but it's acceptable). I think it's because of the OS 2.3.2. Hopefully, those programmers will update their software to work with 2.3.2 soon!
Oh, in additional, I don't think any of those softwares are works with your headset on (bluetooth headset as well).
thak u very much.
i'm looking for an android new phone that support call recorder (2 sides)

Hi there,
Can you please try the app Total Recall Android by Killer Mobile Software for recording calls?
They claim it records calls on Xperia Arc without any modifications or root needed.
I would like to buy this phone to replace a SGS that can record only with 2.2.1 FW...but I would like to know if this realy records bouth sides of the conversation without speaker phone enabled on the actual firmware versions.
Thank you in advance!

Hi, I tried with original, official rom, unrooted phone, and didn't work properly.
The only thing I want to do a 2-way call recording. Now the call recorders doesn't record the called contact's sound.
I read this program's details: CallRecorder - skvalex on market
It says I need root my phone and get another kernel. But which? Can somebody help me?
Does anyone uses a kernel and tested 2-way call recording? Does it work correctly? Pls help me.
