The Double Wide plugin interface — stereo width control
Simple by design

One knob does it all

Turn left to narrow. Turn right to widen. The plugin handles M/S encoding, bass protection, and smoothing automatically.

Narrow

  • +Check mono compatibility before bouncing
  • +Focus bass-heavy elements to the center
  • +Tighten up a loose stereo image

Wide

  • +Open up pads, synths, and ambient layers
  • +Create space around the vocal without EQ
  • +Add dimension to a flat mix bus
Features

Small plugin, serious engineering

The same DSP principles behind our flagship plugins, distilled into a single control.

M/S Processing

True mid-side encoding and decoding. Not a simple pan trick. The stereo field is manipulated at the signal level for clean, phase-coherent width changes.

Bass Mono-izing

The low end is automatically kept centered, even when widening. Your bass stays tight and translation-safe on every playback system.

Smoothed Automation

50 ms parameter smoothing on the width control. Automate freely without clicks, pops, or zipper noise. Smooth transitions guaranteed.

Zero CPU Overhead

Lightweight M/S math with no oversampling, no FFT, no convolution. Use it on every track without thinking about CPU. Zero latency, zero compromise.

Next step: add tone, depth and low-end control

The Double Wide fixes stereo width. The full Buchert Audio bundle adds the other mix dimensions: Tonality EQ for focus, Warmth Engine for tone and glue, Mass Engine for low-end weight, and Depth Engine for front-back placement.

If The Double Wide becomes a regular part of your mix checks, the bundle gives you the complete Buchert Audio chain in one purchase.
