Tokyo Dawn Labs – TDR Special Filters Bundle for WiN

TDR Infrasonic

The TDR Infrasonic targets the largely inaudible low-frequency areas of a mix. This dedicated filter operates in both minimum and mixed phase modes, and features infinitely variable filter tilt, dry mix capability, and a wide range of filter loss compensation methods: a dynamic filter mode and a set of harmonic generators help the operator creatively compensate for any unwanted energy losses associated with the filtering process.

The plug-in is an ideal choice when transferring material to a lower spectral bandwidth medium/media, such as mastering discs, audio tapes, analog broadcasts or PA systems. The creative filter compensation capabilities also make it a valuable tool in all traditional recording, mixing, restoration and mastering applications

The plugin features a modern, resizable user interface. Its low-frequency spectrum analyzer provides exceptionally detailed examination of the lowest mixing registers, down to DC.

Features

• Minimum phase and mixed phase operation
  
• Continuously variable filter tilt
  
• Various power compensation options including dynamic gain mode and harmonic generators
  
• Highly accurate low-frequency spectrum analyzer
  
• Hardware-accelerated user interface with full-screen viewing capability

TDR Elliptical

TDR Elliptical specializes in controlling the width of stereo sound at low frequencies. Elliptical filters operate on the stereo difference channel. They find important applications in disc mastering and in situations where it is necessary to control the amount of location information in a mix.

Unlike traditional elliptical filters, this filter offers smooth slope control, minimum and linear phase modes, and dry mix control. Compensation options ranging from dynamic harmonic generation oscillations to “Haas delays” allow the operator to creatively compensate for the subjective energy losses that occur when filtering and/or summing stereo and mono signals.

The TDR Elliptical features a freely resizable user interface, including a frequency analyzer that allows you to evaluate stereo differences in the lowest registers, down to DC.

Features

• Minimum phase and linear phase operation
• Continuously variable filter tilt angle
• Various filter power compensation options, incl. harmonic generators
• Effective stereo-mono loss compensation
• Hardware-accelerated, resizable user interface that supports full-screen mode
  

Note

Elliptical filters should not be confused with the Elliptical filter specification. The latter is also called Causer or Zolotarev-filter and describes the way to specify “Q” in higher order filters (like Butterworth, Chebichev, Linkwitz-Riley or Bessel filters). Elliptical filters allow ripple in the passband and stopband bands, making them largely unsuitable for use in audio applications.

TDR Ultrasonic

TDR Ultrasonic is a filter designed to control the accumulation of ultrasonic content in oversampled recording, processing or playback chains. The idea is to prevent ultrasound from entering nonlinear systems.

Examples of nonlinear systems include peak limiters, distortion devices, compressors , and other forms of modulation. Analog recording devices such as tape recorders and disc cutting systems also exhibit nonlinear behavior, as do all playback systems (albeit to a lesser extent).

The overall distortion produced by a nonlinear system increases with the bandwidth of the input signal. This is true for both audible and inaudible content, and applies to the entire production process: while a narrowband mono signal such as a guitar or vocal can handle a huge amount of distortion masterfully, a wideband mix can sound disjointed at the slightest degree of saturation.

This is because nonlinearities lead not only to harmonic distortion, but also to intermodulation distortion, a basically non-harmonic type of distortion. This form of distortion results in new frequency distortions based on the sum and difference of the frequencies of the original frequency distortions. As a result, these new partial signals appear outside and below the original frequencies, with the latter possibly falling within the audible range.

TDR Ultrasonic achieves the same effect but on a larger scale. This allows lossless reduction of intermodulation distortion that would otherwise be caused by ultrasound exposure to nonlinear devices.

The freely resizable user interface provides intuitive access to all the traditional filter parameters and a host of exotic features such as a dynamic ultrasonic gate, infinite Nyquist attenuation, and a handy “Bypass All” function for A/B testing the impact of ultrasonic filters on all mixtures. A precise ultrasonic frequency analyzer provides a detailed view of the ultrasonic spectrum and filtering in action.

Features

• Linear phase filtering with smooth tilt angle adjustment
  
• Ultrasonic shutter
  
• Support for sampling rates up to 20 MHz
  
• Hardware-accelerated, freely resizable user interface that supports full-screen mode

TDR Arbiter

TDR Arbiter is a frequency-dependent spectral balancer. This audio plugin, which operates independently of absolute level, is the ideal solution for a wide range of typical audio mixing, restoration and mastering tasks. Whether it is de-essing, dampening blast waves or correcting problems with the overall frequency balance, the level-independent nature of the algorithm allows you to achieve musically convincing results in the shortest possible time and maintain them throughout the entire mix.

Up to three ranges can be specified in the form of a bell, flat top, and traditional shelves. Arbiter supports both positive (ascending) and negative (descending) control ranges, providing intuitive control over the dynamic frequency balance of the signal. A set of harmonic generators allows creative compensation for any losses introduced by filtering, expanding the generally transparent filtering process with a useful set of sonic alternatives.

The plugin features a modern, fully resizable, full-screen user interface. The wideband spectrum analyzer provides insight into the instantaneous magnitude of the filter and how it affects the signal from input to output.

Features

• Musically convincing spectral balance control independent of absolute level
  
• Three freely configurable frequency ranges
  
• Largely preserves the original dynamic structure
  
• Wide operating range
  
• Very low-distortion anti-aliasing algorithm
  
• Support for bell, flat top, low and high shelving shapes
  
• Band-specific and wideband modulation modes
  
• Solo and delta modes
  
• Freely resizable user interface with full-screen capability
