 ffmpeg -i "F:\8.flac" -af
 "pan=7.1|c0=c0|c1=c1|c2=c2|c3=c3|c4=c4|c5=c5|c6=c6|c7=c7" "F:\8.wav"

 ffmpeg -i "F:\8.flac" -af
 "pan=7.1|c0=c0|c1=c1|c2=c2|c3=c3|c4=c4|c5=c5|c6=c6|c7=c7" -c aac
 "F:\8.m4a"

 ffmpeg -i "F:\8.flac" -af
 "pan=7.1|c0=c0|c1=c1|c2=c2|c3=c3|c4=c4|c5=c5|c6=c6|c7=c7" -c dca -strict
 -2 "F:\8.dts"

 flac & wav,LFE is no process,but aac & dca is do EQ and down volume.
 aac & dca,the eq is no same,dca is lower.
