TDR Ultrasonic

TDR Ultrasonic by Tokyo Dawn Labs is a specialized utility filter that manages ultrasonic buildup in oversampled production chains. It prevents inaudible high-frequency content from hitting nonlinear processors like limiters, compressors, and distortion units, where it can create intermodulation distortion that muddies your mix. The plugin offers linear-phase filtering with continuously variable slope, a dynamic ultrasonic gate, and a ‘Bat Mode’ for hearing ultrasonic content. An HF noise generator lets you dither ultrasonics instead of filtering them, and the precise analyzer shows exactly what’s happening. Use it on full mixes, mastering chains, or any project where wideband saturation risks turning harsh. It suits hobby producers and engineers working in FL Studio, Ableton, or Logic who want cleaner, more controlled distortion and a transparent top end. The resizable interface and Bypass All function make A/B testing easy.
