TDR Elliptical is designed to manage stereo width specifically at low frequencies, focusing on the stereo difference channel. This technique is essential in mastering and mixing scenarios where precise control over spatial information is required. By targeting the low-end stereo image, it helps maintain clarity and balance without compromising the overall mix.

Unlike traditional elliptical filters, this plugin offers a continuously adjustable slope, along with minimum and linear phase modes for flexible processing. It includes a dry mix control and various compensation options such as dynamic bump, harmonic generation, and Haas delays. These features enable users to creatively address any perceived energy loss or phase issues caused by filtering or stereo to mono conversion, preserving the integrity of the audio.

The user interface is fully resizable and hardware accelerated, featuring a detailed frequency analyzer that visualizes the stereo difference down to the lowest frequencies. This visual feedback allows for precise adjustments and deeper insight into the stereo field. TDR Elliptical stands out by providing effective compensation for stereo to mono losses and offering both minimum and linear phase operation, making it a powerful tool for mastering engineers and producers.
