TDR Infrasonic focuses on enhancing the low-frequency regions of audio mixes that are often inaudible yet crucial for overall sound quality. It offers flexible filtering options with minimum and mixed phase modes, allowing users to adjust the filter slope continuously for precise control. The plugin includes a dry mix feature and innovative filtering compensation methods such as a dynamic bump mode and harmonic generators, which help restore any energy lost during filtering in a creative manner.

This plugin is particularly useful when preparing audio for mediums or environments with limited spectral bandwidth, including disk mastering, audio cassettes, analog broadcast, or public address systems. Its creative filtering compensation tools also make it a valuable asset across a range of audio production tasks like recording, mixing, restoration, and mastering, ensuring that the low-end content translates well across various playback systems.

Featuring a modern, freely resizable user interface, TDR Infrasonic provides an exceptionally detailed low-frequency spectral analyzer that offers deep insight into the lowest registers of a mix, extending down to DC. The interface is hardware accelerated and full-screen capable, making it both visually accessible and efficient for professional audio workflows.
