Tokyo Dawn Labs TDR Infrasonic v1.0.9

Tokyo Dawn Labs TDR Infrasonic is a low-frequency filtering effect for controlling subsonic content that can be difficult to hear but still needs attention in a mix. It suits producers, mixing engineers and mastering users who want to manage the lowest frequencies while retaining a sense of bass weight.

A continuously adjustable filter slope lets you tailor the filtering, with minimum-phase and mixed-phase modes providing different approaches. The dry mix control allows you to blend in the unfiltered signal. If removing deep lows leaves the result feeling lighter, Dynamic Bump and harmonic generators offer ways to compensate for that perceived loss of energy.

The detailed low-frequency spectrum analyzer extends down to DC, helping you inspect the bottom of the spectrum rather than relying on listening alone. A resizable, hardware-accelerated interface with full-screen support gives the display room to work.

Beyond everyday mixing, Infrasonic is useful for restoration and preparing audio for bandwidth-limited playback or delivery, including cassettes, analogue broadcast and PA systems. This Windows version supports VST2, VST3 and AAX, making it suitable for compatible hosts such as FL Studio and Ableton Live.
