WIDE / learning path

widening your mix without losing mono

from understanding stereo perception to psychoacoustic expansion. seven stages covering panning, M/S, Haas effect, and correlation-safe widening.

1 6 min

what is stereo width

stereo is not just left and right. it is timing, phase, and frequency differences that your brain assembles into a spatial image.

2 8 min

how stereo perception works

interaural time differences, level differences, and spectral cues. the psychoacoustics behind why stereo processing works or fails.

3 7 min

M/S processing explained

mid is what both speakers share. side is what differs. M/S processing lets you manipulate the stereo field in ways panning cannot.

4 9 min

Haas effect and allpass decorrelation

short delays and frequency-dependent phase shifts create width without changing the spectrum. the trade-offs of each approach.

5 8 min

stereo widening on individual tracks

when to widen and when to leave things narrow. practical techniques for vocals, guitars, synths, and drums.

6 10 min

how to widen stereo without phase issues

mono compatibility, correlation meters, and why your wide mix sounds thin on a phone speaker. fixing it before it ships.

7 12 min comparison

stereo imaging plugins compared

from free Ozone Imager to iZotope and beyond. what each tool does differently and which approach suits your workflow.
