Universal Audio Precision K-Stereo Ambience Recovery & Shadow Hills Mastering Compressor plugins announced

Universal Audio UAD-2

Universal Audio has announced the upcoming Precision K-Stereo Ambience Recovery and Shadow Hills Mastering Compressor plugins for its UAD-2 platform.

Created by Universal Audio in collaboration with famed mastering engineer Bob Katz, the K-Stereo Ambience Recovery plug-in extracts ambient cues from source recordings — allowing users to precisely enhance the stereo depth and imaging of mixes without unnatural artifacts.

“The K-Stereo plug-in gives mastering engineers an easy, organic-sounding solution for excessively small mixes or mixes that need more space and depth — from classical to jazz, rock, or hip-hop,” said Bob Katz. “Because we’re effectively ‘pulling out’ the ambience that’s already in the recording, the results sound much more natural. I’m happy to be working with UA to bring K-Stereo to the UAD platform.”

Designed for critical 2-track mastering or post-production applications, the K-Stereo plug-in offers a “do-no-harm” approach to adding depth and width to busy or narrow-sounding mixes. Using elements of the Haas effect and other psychoacoustic principles, the plug-in transparently enhances existing ambience and early reflections without adding artificial reverb or changing the ratio of center elements to side elements.

Precision K-Stereo Ambience Recovery Plug-In features:

  • Unique ambience recovery and stereo processing tool, created and patented by famed mastering engineer Bob Katz.
  • Extracts ambient cues from the source material, naturally adding depth and width to the stereo field.
  • Perfect for fixing busy or “narrow” mixes at the mastering stage.
  • 3-band Ambience Filter EQ for further shaping the effect.
  • Mid/Side gain controls available to adjust the center-to-side balance.
  • Left/Right Gain controls for final stereo image balancing and leveling.
  • Custom user presets created by Bob Katz.

Created by UAD Direct Development partner Brainworx and Shadow Hills Industries founder Peter Reardon, this true-to-life plug-in emulation of the hallmark Mastering Compressor expertly tempers dynamics and tames transients like no other device on the market.

“The Shadow Hills Mastering Compressor hardware is capable of delivering so much character and color, from subtle to very dramatic. It was important to me that any plug-in emulation provided the same sonic experience,” said Shadow Hills’ Peter Reardon. “Thankfully, the team at Brainworx and Universal Audio have faithfully brought this hardware product to life in the digital world.”

As the go-to compressor on recordings by Muse, Gnarls Barkley, Coldplay, John Mayer, Regina Spektor, and more, the Shadow Hills Mastering Compressor features a world-class signal path, controlling music dynamics in two stages — first with an Optical section, then with a Discrete (VCA) section. Both sections can be bypassed, providing a variety of compression sounds (Optical, Discrete, and combined) from a velvet touch to an iron fist.

Like the hardware version, the Shadow Hills Mastering Compressor plug-in offers selection of three distinct output transformers (Nickel, Iron, and Steel) — taking the signal from “clean” to “colored” and “dirty” — as if selecting from the output stages of three distinct classic analog consoles.

Whether employed on a vocal chain, drum buss, or on the master fader, the Shadow Hills Mastering Compressor’s unique control and character will inspire creativity.

Shadow Hills Mastering Compressor Plug-In features

  • Meticulous emulation of the Shadow Hills Mastering Compressor, licensed and endorsed by Peter Reardon.
  • Created by Brainworx, developed exclusively for the UAD Powered Plug-Ins platform.
  • Separate Optical and Discrete (VCA) dynamics sections for two-stage serial dynamics control.
  • Transformer matrix switches between Nickel, Iron, and Steel output transformers — like selecting between 3 distinct vintage console outputs.
  • 90Hz sidechain filtering for musical compression of low-frequency program material.
  • Large, accurate VU meters provide Optical, Discrete, or Output gain views.
  • Custom presets created by Shadow Hills founder and designer Peter Reardon.

Both plug-in are available as part of the upcoming UAD Software v6.3.2 release, scheduled for early November. The Precision K-Stereo Ambience Recovery Plug-In will be $199 USD, the Shadow Hills Mastering Compressor will be $299 USD.
