Stereo is a huge part of every modern song/mixdown. We all use it and listen to it every day.
However, not many people know that using the wrong kind of stereo widening techniques can severely damage your song.
Techniques such as HAAS effect, Mid Side, Frequency Shifter, pitch shifting and even chorus (if used incorrectly) can cause huge problems in your mixdown. There are even some expensive 3rd party plugins that cause problems right out of the box.
These stereo widening techniques may give you a wide sound, but they have bad mono compatibility, and phase issues.
So, when summed to mono, this can make your song sound soft, mushy, distant, lose punch and lose bass.
This could be happening right now and if so, it's not your fault. You've just been taught the wrong techniques.
That's why I made this free video lesson, and why I made the plugin i demonstrate in the video.
