D16 Frontier Free VST Compressor

Available for free

Frontier is available only for registered D16 software users, who have purchased any product in the past or will do it in the future. It is available free of charge.

Multitude of applications

Quality and performance makes Frontier a perfect tool for almost any studio situation. Its simple and clear interface in combination with excellent sound quality will surely be appreciated by any engineer looking for efficient way of controlling dynamics of a channel, bus or even master output. Frontier can be used as very transparent mixing / mastering limiter (at certain settings) with just licking the loudest amplitude peaks, or can be utilized more creatively, as sound shaper, when more extreme settings are at stake.


Algorithm for automatic gain makeup used in Frontier automatically normalizes the signal’s volume after it passes limiting section. It contributes to efficiency boost of setting the plug-in up.

Release your creativity

Mind that Frontier is not just simple a limiter. With selectable Control Input and optional Soft Clipping you get in your hands a quite versatile and creativity-releasing tool. Appropriately configured in your DAW Frontier can act as e.g. mono ducker (using Left or Right channel as control signal for the input feed). Or enabled soft-clip option in combination with more drastic settings will reveal Frontier’s wave-shaping capabilities. Surely with time you’ll find more and more applications for this useful unit.

TDR Kotelnikov

TDR Kotelnikov is a wideband dynamics processor combining high fidelity dynamic range control with deep musical flexibility. As a descendant of the venerable TDR Feedback Compressor product family, Kotelnikov has directly inherited several unique features such as a proven control scheme, individual release control for peak and RMS content, an intuitive user interface, and powerful, state of the art, high-precision algorithms.

Free Compression VST: 5 Must have Plugins With a sonic signature best described as “stealthy”, Kotelnikov has the ability to manipulate the dynamic range by dramatic amounts, while carefully preserving the original tone, timbre and punch of a musical signal. As such, it is perfectly suited to stereo bus compression as well as other critical applications.

The concept is “proudly digital” in the sense that it doesn’t try to emulate any previously existing device. This is the original!

Key specs and features

  • 64bit multi-rate processing structure for highest accuracy
  • “Delta” oversampled signal path (bit transparent at 0dB gain reduction)
  • Super fast, yet natural sounding compression
  • “Crest factor” based control scheme offering independent release controls for peak and RMS events
  • Flexible sidechain highpass filter
  • Advanced stereo linking options optimized for the stereo bus
  • Delta preview mode previews the difference between compressed and original signal
  • Latency compensated, click free bypass (i.e. processing never interrupted)
  • User interface rescaling (100%, 125%, 150%)
