im not sure if windows has the ability to 'pipe' like a *nix system does.. but this works to pipe the output of ffmpeg to ffplay instead of a file.. 

hope this helps...

ffmpeg -i test_15kHz.mp3 -filter_complex "volume=1,highpass=f=12000,highpass=f=12000,highpass=f=12000,highpass=f=12000[a0];aevalsrc="sin\(12000*2*PI*t\)":c=stereo:s=44100[a1];[a0][a1]amultiply,lowpass=f=10000,lowpass=f=10000,lowpass=f=10000,lowpass=f=10000" -y -f wav - | ffplay -f wav -
