Android Question Capture phone call received audio.

[canalrun]

Hello,
I would like to capture the received audio buffers during a phone call to feed into the Microsoft Cognitive Services speech-recognition API.

Looking at the Android documentation, the B4A AudioStreamer, and a previous reply from Erel it appears that it is not possible.

Is that true? It is not possible to capture the phone call received audio buffers?

Thanks,
Barry.
