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.
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)
The improved “Gentleman’s Edition” is available here.
This is one of the first software compressors that doesn't annoy me on program... Very nice!Michael Hynes (mastering engineer)
Wow this plug in compressor is on par with hardware compressors. It is clean and at the same time it sits the mix and everything just sounds better.Glenn Buccy (audio engineer)
It’s safe to say that the new TDR Kotelnikov is quite possibly the most transparent mastering compressor on the freeware market (and beyond).Bedroom Producers Blog
