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.
Hi Guys, If you want to record your phone calls, there is an excellent software for the ATOM-- it is called PM Recorder. I have been using it for the past month and sound quality is very good. However, you have to activate speakerphone in your Atom to record both side of the conversation.Here's the link:

Does anyone has any voice and call recording software for TMO Wing?
Thanks in Advance
vito audio notes is a pretty good program. It auto records calls, but it isn't very clear unless you use the speaker phone. For some reason it used to work alot better on the tmo dash than it does on my wing.
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
I think the most popular VoIP call recording app is Cube ACR. When I tried to record a Messenger call using Cube ACR, I noticed that only my voice is being recorded. When I tried Universal Call Recorder app by SPARKLING APPS and it was recording the calls very well, but the problem is that another person hears me worse (at a lower volume) and he hears the echo of his voice, even when I use the earphones. My mom has Xiaomi Redmi Note 7 and it perfectly records VoIP calls on Cube ACR and there are no side effects. I also tried IntCall recorder from ApkPure and when I try to play my recording, it says that my device probably doesn't support VoIP call recording. Is there any possibility that H990DS could record VoIP calls without any side effects? I use Lineage OS 18.1 BTW.
