How stereo widening works
What width actually is
A stereo file is two channels, and how wide it sounds depends on how much they differ. Content identical in both ears is heard dead centre; content that differs is heard as spread. Widening works on that difference — it turns up what the two channels do not have in common and leaves the shared part alone.
That is why widening a mono file does nothing. There is no difference to amplify.
Check it in mono before you keep it
This is the trap. Widening is usually done by pushing the two channels further apart, and the further apart they get, the more they cancel when something later sums them back together — a phone speaker, a Bluetooth speaker, a club system, a supermarket PA. A mix that sounds huge in headphones can lose its whole centre in mono.
Set the width, then drop the control to 0% and listen. If the vocal disappears or the track suddenly sounds thin, you have gone too far.
Keep the low end centred
Bass carries most of the energy, and spreading it wastes that energy and makes the low end vague. Wide works on cymbals, pads, backing vocals, synths and room ambience. Kick and bass are better left in the middle. Almost every commercial master is arranged this way.
Going the other way
The same control at 0% collapses a stereo file to mono, which is genuinely useful — for a single voice recorded with an accidental channel imbalance, for a sample that has to sit in one place in a mix, or for checking the compatibility described above.
