What is mid side encoding?
Mid/side (sometimes called sum/difference) is an alternative way of using two channels of audio to represent stereo information. In that sense, it's actually got a bit in common with left/right stereo. In fact, the connection between mid/side and left/right goes even further.
How does Mid Side stereo work?
In the digital era, mid/side processing plug-ins work by converting a stereo track into two signals. The Mid signal contains the information that shows up in both speakers, while the Side signal contains the information that is unique to the left and right speakers.
What is the formula used to calculate the mid of mid side?
Creating the Mid Channel
If the “sides” channel is created by taking the difference between “left” and “right,” the “mid” channel is created by taking the sum of “left” and “right,” or mid = 0.5*(left + right).
