Could you give these 2 debug builds a try?

These debug builds disable encoding/compression and will dump the raw audio that Android provides into a .wav file.

If it still produces empty files, then either the device doesn't support call recording or the ROM you're running isn't compatible. Call recording requires the modem, kernel, vendor firmware, and ROM to all be compatible for it to work. On some devices, even the original ROM won't work because the manufacturer never bothered to implement the feature.

(Also, thanks for the [edit]. I'll make sure the next version of BCR no longer logs the phone number. EDIT: Unfortunately, while I can stop BCR's logging, Android's MediaProvider ends up logging the filename anyway.)

Hi, thanks for your debug builds, it still produces empty files, I think this is ROM's problem?(sorry, I don't have ability to confirm this) I am trying to contact the ROM's support. Here is the logcat file: logcat.txt logcat.txt

Hi, I tried this call recorder and also failed. (https://gitlab.com/axet/android-call-recorder) The rom maintainer said that "Call recording on custom roms is difficult" And axet said "MOST PHONES DOES NOT SUPPORT CALL RECORDING. Blame Google or your phone manufacturer not me!" on gitlab

I had the same problem (lineageOS 20, magisk 26.1). I first tried Axet Call Recorder app and I got empty recordings. Then I tried this app and also got empty recordings. Then I switched to FLAC as explained by @bolltzain and it's working!

edi:t after switching to FLAC I retried ogg and it also worked.
