TDR Elliptical 专门用于控制低频立体声宽度。椭圆滤波器作用于立体声差异通道。它们在光盘母版制作以及混音中需要控制大量位置信息时都具有重要的应用。

与传统的椭圆滤波器不同，该滤波器提供连续可变斜率、最小和线性相位模式以及干混音控制。从谐波发生器上的动态凹凸到“Haas 延迟”，各种补偿选项使操作员能够创造性地抵消滤波和/或立体声到单声道叠加带来的主观能量损失。

TDR Elliptical 配备可自由调整大小的用户界面，包括一个频率分析仪，可深入了解最低音域直至直流的立体声差异。

Distinguishing Features:
最小相位和线性相位操作；
Continuously variable filter slopes;
各种滤波器能量补偿选项，包括谐波发生器；
有效的“立体声到单声道”损耗补偿；
可自由调整大小的硬件加速用户界面，支持全屏

显示。注意：椭圆滤波器与椭圆滤波器规格不同。后者也称为 Causer 滤波器或 Zolotarev 滤波器，描述了一种在高阶滤波器（类似于巴特沃斯滤波器、切比雪夫滤波器、林奎茨-莱利滤波器或贝塞尔滤波器）中指定“Q”值的方法。椭圆滤波器在阻带和通带中均能容忍波纹，这使其在音频应用中显得力不从心。

TDR Elliptical specializes in controlling the stereo width at low frequencies. Elliptical filters operate on the stereo difference channel. They have important applications in disk mastering, and whenever the amount of positional information in a mix asks for control.

Contrary to traditional elliptical filters, this filter offers a continuously variable slope, minimum and linear phase modes, and a dry mix control. Various compensation options ranging from Dynamic Bump over harmonic generators to “Haas delays”, permit the operator to creatively counter-act subjective energy losses introduced by the filtering and/or stereo to mono summing.

TDR Elliptical comes with a freely resizable user interface, including a frequency analyzer that offers insight into the stereo difference at lowest registers, down to DC.

Notable Features
Minimum phase and linear phase operation
Continuously variable filter slope
Various filter energy compensation options, incl. Harmonic generators
Effective “stereo to mono” loss compensation
Freely resizable hardware accelerated user interface, full-screen capable

Note: Elliptical filters are not to be confused with Elliptic filter specification. The latter is also called a Causer or Zolotarev-filter, and describes a way to specify “Q” in higher order filters (much like Butterworth, Chebychev, Linkwitz-Riley or Bessel). Elliptic filters tolerate ripple both in the stopband and passband, making them largely inadequate in audio applications.
