The TDR Special Filters Bundle Black Friday deal puts four Tokyo Dawn Labs filter plugins into one purchase at $49, which is 51% off, with the offer ending Nov 19, 2026.
The bundle covers TDR Arbiter, TDR Elliptical, TDR Infrasonic and TDR Ultrasonic. Each one targets a different job: spectral balance, low-frequency stereo width, sub-bass control and ultrasonic build-up.
Arbiter is a frequency-selective spectral balancer. It works on a relative basis, so the effect does not depend on the input level, and the maker says that leaves the original dynamic structure largely intact.
That makes it a fit for de-essing, plosive control or broad frequency balance fixes. You get up to six bands in bell, flat top, low shelf and high shelf shapes, with both upward and downward control ranges.
Harmonic generators can put back some of what the filtering takes out. A wideband spectral analyzer shows the filter magnitude and how it changes the signal from input to output.
TDR Elliptical works on the stereo difference channel to control width at low frequencies. It can act on either stereo difference or stereo correlation, and it offers minimum and linear phase modes, a continuously variable slope and a dry mix control.
Compensation options include Dynamic Bump, harmonic generators and Haas delays. They are there to counter the perceived energy loss from filtering or from summing to mono. The maker points to disk mastering as a key use.
TDR Infrasonic handles the lowest registers of a mix. It has a continuously variable slope, minimum and mixed phase modes, a dry mix option and subwoofer channel creation.
Its analyzer reads down to DC. The maker lists disk mastering, audio cassettes, analogue broadcast and P.A. systems as targets when material moves to a medium with less spectral bandwidth.
Ultrasonic is built for oversampled chains where nonlinear processors such as limiters, distortion devices and compressors can react to content above the audible range. The maker's reasoning is that distortion grows with signal bandwidth, and that includes intermodulation distortion.
It uses linear phase filtering with a continuously variable slope. It also has a Dynamic Ultrasonic Gate, enforced infinite attenuation at Nyquist and a Bypass All switch for A/B tests across a whole mix.
"Bat Mode" lets you hear the ultrasonic content, and an HF noise generator can dither it as an alternative to filtering. Sample rates up to 20MHz are supported.
All four plugins share a freely resizable, full-screen capable interface, with a built-in analyzer in each.
Yes. The Black Friday deal on the TDR Special Filters Bundle is 51% off, bringing it to $49, and it runs until Nov 19, 2026. One purchase gets you all four Tokyo Dawn Labs filters.
The bundle holds four Tokyo Dawn Labs plugins: TDR Arbiter, a spectral balancer; TDR Elliptical, an elliptical equalizer; TDR Infrasonic, a low-frequency filter; and TDR Ultrasonic, a filter for ultrasonic content.
It filters the stereo difference channel to control low-frequency width. You can target stereo difference or stereo correlation, work in minimum or linear phase, and use compensation such as harmonic generators or Haas delays to offset the loss.
Up to six bands, each set as a bell, flat top, low shelf or high shelf shape. It handles upward and downward control, and its relative process works independently of input level, which suits de-essing and plosive control.
