KResearch

KR-Space is a modular multi-effect plug-in which can produce a multitude of different types of effects

From traditional echoes and reverbs, to very complex soundscapes, modulation and filtering effects, resonating echoes and reflections, saturation effects and other types of unusual effects.

To achieve this wide range of effect creation KR-Space uses a proprietary design and a flexible modular architecture where the different available modules can be switched on and off or routed in various combinations allowing more flexibility in effect design.

The modular architecture also allows more efficient CPU utilization since only the modules that are switched on contribute to the CPU overhead.

KR-Space introduces the Animated Object Space Emulator (AOSE) where the user has control over a number of spherical objects which are placed in the virtual environment and affect the sound output in a multitude of ways. These objects have various user controlled characteristics like size, resonance, oscillation frequency, reflection characteristics, etc. and can be animated (moved) in the virtual environment affecting the sound output.

Additionally, the main reverberation engine features separate damping controls for early and late reflections allowing more detail filtering control, thus expanding the total range of available effects. It also introduces KResearch’s Asymmetric Reflection Scheme for more realistic reverb and echoes creation.

KR-Image STR – Stereo Image Enhancer audio plug-in

In a conventional stereo imager enhancer design the input audio signal is divided 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 which divides the signal in hundreds of individual frequency components allowing a very detailed expansion of the input signal.

The KR-Imager STR supports two stereo image methods and an additional freeze morph function which are used to provide dynamic time variable stereo imaging. Changing the selected algorithm results in different frequency responses according to a user spcified change rate. The morph method provides a setting that combines two different algorithms in realtime. The KR-Imager STR engine allows for the use of sweeps and stereo image animations, further enriching the resulting stereo image.

The KR-Imager STR output is spectrally neutral and balanced at all times, i.e. it does not change the inputs frequency components (NO additional coloring of input audio signal), instead it only widens the stereo image for more pleasant listening. To achieve this, KR-Imager STR uses Spectral Transformation Resynthesis (STR) processing – a frequency depended DSP technique.

Features

• Primary and Secondary “Shape”algorithm selection control
• Effect “Depth” control
• Algorithm “Sweep” speed control
• Morph enable control
• Morph speed control
• Morph Freeze enable control
• Morph algorithm mix control for freezed morphing.
• Left/Right/Both input channel selector

KR-Fatter STR is a modular hybrid plug-in processor using two different proprietary time and frequency domain DSP platforms in a single unit.

KR-Fatter STR can be used to enhance the spectral content of audio signals containing vocal, instrument or synthesized sound recordings. By using different combinations of the available modules KR-Fatter STR allows the creation of different effects like Fattening, Spectral Coloring, Imaging, Harmonizing, Pitch Shifting, Delay, Modulation and other Special effects.

Special attention was given in the design of this processor in the use of “Naturally perceived” randomization of the available functions in order to produce a spectrally evolving output. These randomizations implemented using Fractal algorithms can transform dull static audio signals into vibrant, rich and natural sounding recordings.

The available modules and functions can be employed in both serial and parallel fashion to achieve different results. KR-Fatter STR can create up to an additional 4 stereo copies of the input signal which can be processed individually by applying modular effects and mixed together in a final master stereo output bus.

Features

• Generic pitch-shifter: generate pitch related variations of the original audio signal.
• Animated pitch variation: produce animated pitch variations.
• STR color (STR transform filter): design thousands of different spectral color variations of the original input audio spectrum.
• Low frequency oscillator (LFO) modulation: give vibrato effect.
• Phase: add naturally perceived phase related variations.
• Amplifier: add naturally perceived amplitude related variations.
• Shelving equalizer (EQ): use to spectrally balance individual channels and/or the whole mix.
• Delay: use to create delayed copies of the input.
• Panning: use to create imaging effects or expansion.
