Any Call Recorders that are digital - not using my microphone to listen to what is said in the other end?

What about recording calls over Bluetooth?

(It seems most most of these applications record what goes into my microphone, and listen to the other side through my microphone, often turning up the speaker to do that)

No its not a duplicate because most of these apps are using the microphone – Olav Mar 15 '12 at 22:02
- I think they work by recording anything going into the mic, and they turn on the speakerphone, to listen to the other side. – Olav Mar 16 '12 at 9:20
I'm confused about what you're asking for. Are you looking for an app that only records one side of the conversation? – Mr. Buster Mar 22 '12 at 20:53
No, but the difficult thing is the other side. – Olav Mar 23 '12 at 8:04

Sorry to inform you: But that's a limitation in the system itself. Android simply doesn't allow this, and offers no API to record the "remote side" -- which is the reason it's hard to find any app doing so satisfactory. You will find several developer discussions on this topic, and it seems it turned out "being hard to work around that limitation" is a big euphemism.

I still find it bewildering how old Nokia phones can and has the option to record voice calls built-in to the phone whereas, something as advanced as an Android would fall short of such feature. – Propeller Aug 3 '12 at 15:04
It's clearly not a hardware issue, and I agree with you: every old-fashioned analog fixed-line can record calls, so this can't be some legal issue either. To not spy on you, there could be some permission used (the permission system IMHO could also use some overhaul -- e.g. permission.INTERNET could be a bit more finegrained) -- so I really see no reason to completely block this. Unfortunately, I have no say in this area -- I'm not important enough to make Google listen... – Izzy Aug 3 '12 at 15:17
We should start a petition then :) – Propeller Aug 3 '12 at 16:33
Which one? Just take a look at all the tickets currently open on Androids bug tracker. There already have been plenty, and for years -- but they simply get closed with the argument "works as designed"... – Izzy Aug 3 '12 at 18:00

This is something that has to be enabled in the kernel. Some custom kernels do implement this, depending on your device.

This is the most correct answer here. With proper custom kernel support, you very much can have 2-way call recording, often abbreviated as 2WCR. – Harsha K Apr 27 at 20:06
