MDW® Hi-Res Parametric EQ


MDW Hi-Res Parametric EQ 3.0 (TDM/RTAS)

Developed by the creator of the parametric EQ, George Massenburg, the Massenburg DesignWorks® Hi-Res Parametric EQ plug-in continues to define the state-of-the-art in equalization. Originally designed exclusively for Pro Tools|HD systems, version 5 offers new AAX DSP and AAX Native 32/64-bit format support, giving you the flexibility to use the EQ across the entire Pro Tools 10 and 11-based product line, including Pro Tools|HDX systems.

With its unprecedented clarity, smoothness, and excellent high-frequency response, MDW Hi-Res Parametric EQ will help you achieve optimal audio definition in your mixes.

  • Process audio in 64-bit floating point resolution using the AAX format (version 5 only)
  • Select frequencies from 10 Hz–41 kHz, with variable Q and a choice of 3- or 5-band EQ
  • Refine sounds using constant shape reciprocal filter curves from the industry-standard reference
  • Quickly solo a target frequency band using the IsoPeak® functionality
  • Compare settings fast with the A/B snapshots capability

Target frequencies with precision

Quickly find frequencies and reshape sounds to achieve better mixes. View the frequency grid in 6, 12, or 24 dB resolution for easier editing. Sweep through the frequency spectrum to quickly isolate a frequency with IsoPeak. Toggle between two EQ band settings using A/B snapshots. Shape sounds with variable Qs (adjustable bandwidths)—from 25.6 (1/18 of an octave) to 0.1 (6-2/3 octaves)—with unmatched precision. And when used with S6, ICON or other Pro Tools-enabled control surface, the EQ organizes the bands into ergonomic groups—right on your channel strips.

High-resolution filtering

MDW Hi-Res Parametric EQ delivers optimal clarity with natural-sounding results—no matter which version you use. Process audio at 64-bit floating-point resolution when using MDW Hi-Res Parametric EQ 5. Or get double-precision 48-bit processing when you use MDW Hi-Res Parametric EQ 3 with Pro Tools|HD (TDM) systems. You get increased headroom, fewer artifacts, and more predictable filter curves—unlike generic EQs—plus full support for up to 192 kHz audio.

Excellent DSP efficiency

When using MDW Hi-Res Parametric EQ 5 with Pro Tools|HDX systems, you can select the 5-band EQ for enhanced efficiency or the 3-band EQ for even greater instance counts. With the 5-band EQ, you can instantiate eight, nine, or four instances of the plug-in at 48 kHz, 96 kHz, and 192 kHz, respectively. With the 3-band EQ, you can instantiate 10, 13, or six instances of the plug-in at 48 kHz, 96 kHz, and 192 kHz, respectively.

If you’re using MDW Hi-Res Parametric EQ 3 (TDM), you can instantiate the 5-band EQ up to four times per DSP chip at 48 kHz and 96 kHz on Pro Tools|HD Accel systems, or up to eight times per DSP chip with the 3-band version.
