KR-Imager STR is a stereo image enhancement audio plugin with unique processing capabilities.

In a conventional stereo image enhancer design, the input audio signal is split into a very small number of frequency bands using time-domain filters, which are then used to distribute the filtered results to the left and right stereo audio channels. KR-Imager STR uses a frequency-domain engine that splits the signal into hundreds of individual frequency components, allowing for a highly detailed expansion of the input audio signal using user-selectable algorithms.

KR-Imager STR is compatible with two stereo image animation methods and an additional freeze function that are used to provide time-varying dynamic stereo images. Primarily, the algorithmic sweep method, while the selected algorithmic 'filter' or transformation changes the frequency response bands according to a user-specified rate of change. In addition, a transformation method, while two different algorithms are combined (transformed) in real time according to a user-specified rate. The KR-Imager STR engine allows the use of stereo image sweep and transformation animation methods individually or simultaneously, which further enriches the variations of the resulting stereo image.

The KR-Imager STR can be used to process MONO stereo image audio signals, as well as to enhance existing STEREO audio material. When used with existing STEREO audio, KR-Imager STR further enhances the existing stereo image by expanding the input audio signal in its output. The KR-Imager STR audio output signal is spectrally neutral and balanced at all times, that is, it does not change the input frequency components (WITHOUT additional coloration of the input audio signal), but only expands the stereo image for a more pleasant listening experience.
