Title: Missing SR and SL Channels Upmixing 2 channel mono songs
Post by: eascart on December 27, 2016, 12:23:47 AM
I noticed that AC3Filter creates SR and SL Channels in auto matrix by adding 0.5 and -0.5 from L/R channels so in case of original mono files recorded as stereo (2 channels mono) the two waves are the same as the result returns zero. Is there any workaround insted of turning off auto matrix and setting both values positive? Could the creatores of AC3Filter make it recognize the null channels correcting and creating the rear channels? One soluction I tried was using Musereo to create a fake stereo so L and R would become different waves, but I want to preserve the original recording sound.
