TDR Kotelnikov ~ Wideband Dynamics Processor


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!

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%)

fdkaac ~ Command Line Frontend For libfdk-aac Encoder


dkaac reads linear PCM audio in either WAV, raw PCM, or CAF format,
and encodes it into either M4A / AAC file.

If the input file is "-", data is read from stdin. Likewise, if the
output file is "-", data is written to stdout if one of streamable AAC
transport formats are selected by **-f**.

When CAF input and M4A output is used, tags in CAF file are copied into
the resulting M4A.
