But you will need to reduce levels to avoid clipping.

If you want to hear how dramatic the effect is set "Copy: L=0 R=0" to mute the front channels and only hear the surrounds.Īlso because perception of volume is non-linear the correct way to mix 2 channels is to use a factor of 0.7071 (half of sqrt(2)) instead of 0.5. With a Hafler circuit the sound stage is still in front of you but you get ambient audio around you. With your method when listening to music you feel like you are "inside" the band which is unnatural.

On most vocal recordings you will only hear the stereo audio in the rears which makes a dramatic difference in the sound stage. This takes the difference in phase between the left and right channels to create the surrounds. (Replace the filter frequencies with the capabilities of your speakers and sub.) I see that you are merely copying the L and R to SL, SR, RL, RR:Ĭopy: L=L R=R C=0.5*L+0.5*R LFE=0.5*L+0.5*R RL=L RR=R SL=L SR=R
