Great! By the way, you can really improve the quality of your sound by removing the ''-r8k" from rtl_fm and using sox to lowpass/resample the 16k to 8k. The resampler built into rtl_fm is terrible.

Sorry
when decode AIS, same issue and the last commit change nothing for this command:
rtl_fm -f161.975M -p39 -s25k -g50 -r25k -F9 |c:\sox1441\sox -r25k -t raw -es -b 16 - -traw -r48k -es -b16 -c1 - | c:\sox1441\sox -r48k -traw -es -b16 -c1 -V4 - -t waveaudio 1
A few seconds after start rtl_fm CPU load is 100%

Odd, I that one works fine for me. Though please remove the "-r25k" from the rtl_fm command. Don't use it -r ever. I would have deleted the entire feature from rtl_fm long ago but it is sort of needed for wbfm mode.
