If my memory is not totally messed up, it must be like this: (L is original left signal, R is original right signal) Signal Left Right Mono 0.5*(L+R) 0.5*(L+R) Normal L R Variable k*L+(1-k)*R (1-k)*L+k*R with 0.5< k <1 (mono is k=0.5 and normal is k=1) but if you go over one with k, you see negative amounts of the other channel. If L=R (mono source) then nothing changes. mr.escape At 13:43 19.11.2003, you wrote: >I have just one question concerning this issue: what difference would I >hear/see on a scope if the stereo separation was wider (e.g. with the two >different frequencies on left and right)?
