Here are the sox commands used to make the wave files:
sox -D -r16000 -b 16 -e signed-integer -n sox-5to1_nd.wav synth 10 sine 3200
sox -r16000 -b 16 -e signed-integer -n sox-5to1.wav synth 10 sine 3200
sox -D -r16000 -b 16 -e signed-integer -n sox-4to1_nd.wav synth 10 sine 4000
sox -r16000 -b 16 -e signed-integer -n sox-4to1.wav synth 10 sine 4000
sox -r16000 -b 16 -e signed-integer -n sox-4to1_dsd.wav synth 10 sine 3999 gain -.001
sox -D -r16000 -b 16 -e signed-integer -n sox-4to1_sd.wav synth 10 sine 3999 gain -.001
