TDR Ultrasonic is a filter designed to control the accumulation of ultrasonic content in an oversampled recording, processing or playback link. Its purpose is to prevent ultrasound from entering a nonlinear system.

Examples of nonlinear systems include peak limiters, creative distortion devices, compressors, and other forms of modulation. Analog capture devices (such as tape recorders and platter systems) also exhibit nonlinear behavior, as do all playback systems (albeit to a lesser extent).

The total distortion produced by a non-linear system increases with the bandwidth of the input signal. This applies to both audible and inaudible content, and it applies to the entire production process: while narrowband mono signals (such as guitars or vocals) can artfully handle a large amount of distortion, wideband mixes require only a tiny amount of saturation to collapse aurally.

This is because nonlinearity produces not only harmonic distortion, but also intermodulation distortion, which is a largely nonharmonic distortion. This distortion creates new crossovers at the sum and difference of the original crossover frequencies. As a result, these new crossovers end up either above or below the source frequency, which may end up in the audible bandwidth.

TDR Ultrasound can be controlled over a wider range of the same effect. It non-destructively reduces the intermodulation distortion caused when ultrasonic content enters a non-linear device. It can be

The freely resizable user interface provides intuitive access to all conventional filter parameters and a host of nifty tricks, such as dynamic ultrasonic thresholds, forced infinite attenuation at Nyquist frequencies, and a simple "bypass all" function that allows A/B testing of the ultrasonic filter's effect on the entire mix. A precise ultrasonic frequency analyzer provides detailed insight into the ultrasonic spectrum and filtering effects.

TDR Ultrasonic is a filter designed to control the accumulation of ultrasonic content in oversampled recording, processing, or playback chains. The idea is to prevent ultrasonics from running into nonlinear systems. idea is to prevent ultrasonics from running into nonlinear systems.

Examples of nonlinear systems are peak limiters, creative distortion devices, compressors, and other forms of modulation. Analog capture devices such Analog capture devices such as tape recorders and disc cutting systems also exhibit nonlinear behavior, as do all playback systems (albeit to a lesser degree).

The total distortion produced by a nonlinear system grows with the incoming signal bandwidth. This is true for both audible and inaudible content, and This is true for both audible and inaudible content, and applies throughout production: While a narrow-band monophonic signal such as guitars or vocals can artistically handle huge amounts of distortion, a While a narrow-band monophonic signal such as guitars or vocals can artistically handle huge amounts of distortion, a wideband mix can audibly fall apart with only the slightest amount of saturation.

This is because nonlinearities not only produce harmonic distortion but also intermodulation distortion, a largely non-harmonic type of distortion. This form of distortion produces new partials at the sum and difference of the original partials' frequencies. As a result, these new partials end up beyond and below the source frequencies, with the latter possibly ending up as the source frequencies. This form of distortion produces new partials at the sum and difference of the original partials' frequencies. As a result, these new partials end up beyond and below the source frequencies, with the latter possibly ending up in the audible bandwidth.

TDR Ultrasonic controls the same effect, on a larger scale. It allows for losslessly reducing the amount of intermodulation distortion otherwise It allows for losslessly reducing the amount of intermodulation distortion otherwise provoked by ultrasonic content running into nonlinear devices.

A freely resizable user interface provides intuitive access to all traditional filter parameters and a set of exotic tricks such as a Dynamic Ultrasonic Gate, the enforcement of infinite attenuation at Nyquist, and a neat "Bypass All" function allowing for A/B testing of the Nyquist.
