Step-by-Step Guide

  1. Keep kick, bass, snare, and lead vocal dead center and mono. These elements anchor the mix.
  2. Pan rhythm guitars, synths, and percussion to create a stereo field. Use complementary panning (e.g., guitar left, keyboard right).
  3. Use stereo reverbs and delays to create depth. Different pre-delay times on left and right add natural width.
  4. Boost highs on the sides (8-12 kHz) for air. High-pass sides at 100-200 Hz to keep bass centered.
  5. Sum to mono and listen. Nothing should disappear. Use a correlation meter and keep readings above 0.5.
  6. Apply width plugins to specific elements, not the entire mix. 20-30% width increase is usually enough.

Frequently Asked Questions

Why does my mix sound narrow compared to commercial tracks?
Commercial mixes use multiple width techniques: doubled performances, stereo reverbs, M/S processing, and careful panning. They also have more elements filling the stereo field. Start by adding complementary panning and stereo reverb to your mix.
Can I make a mono recording sound stereo?
Yes, but with limitations. Use the Haas effect, chorus, or stereo reverb to add width. For best results, re-record with stereo microphones or double the performance and pan the takes left and right.
What is the Haas effect and when should I use it?
The Haas effect creates width by delaying one side of a stereo signal by 10-30ms. It works well on background elements but can cause phase issues. Always check mono compatibility when using Haas delays.
How do I keep my bass mono while making everything else wide?
Use mid-side EQ to high-pass the side channel at 100-200 Hz. This removes bass frequencies from the sides while leaving them in the center. Also, keep bass synths and kick drums in mono.
Do width plugins work on the master bus?
They can, but use them sparingly on the master. 10-15% width increase is usually enough. Excessive master bus widening causes phase issues and makes mastering difficult.
What is a correlation meter and how do I read it?
A correlation meter measures phase relationship between left and right channels. +1 means fully mono-compatible. 0 means maximum width. Below 0 indicates phase cancellation. Keep your mix above 0.5 for good mono compatibility.
