Stereo Width
Definition
The perceived breadth of the stereo image in a mix. Narrow mixes sound focused and mono-compatible; wide mixes create expansive space but may suffer phase cancellation issues in mono playback.
In Simple Terms
How wide your mix sounds—from narrow and focused to spread-out and expansive. Too narrow and the mix sounds small; too wide and it falls apart on mono speakers like phones.
In Practice
A stereo width processor on a synthesizer pad expands the side content, making the pad feel like it extends beyond the speakers while keeping centered elements tight and focused.
Common Confusion
Wider does not equal better. Heavy width enhancement on every element thins the mix, blurs imaging, and creates phase issues that destroy mono compatibility. Width is most effective when used selectively — wide pads and effects, focused vocals and kicks. The ear perceives contrast, not absolute width.
