The NI-SPEKTRAL DELAY differs from the many other audio effects in that it uses real-time FFT (Fast Fourier Transformation) to split each channel of a stereo signal into as many as 160 separately modifiable frequency bands (even up to 1024 bands internally). The level, delay time and feedback amount for each of this bands can be set separately. Additionally, various modulation effects can be applied to the signal in the frequency domain, which allows for even further sound manipulation.

The NI-SPEKTRAL DELAY offers more than exceptionally great possibilities for creative sound design - from subtle corrections and rich effects to the total alienation of the input signal. Never the less, the NI-SPEKTRAL DELAY is easy to use since all parameters are controlled intuitively and comfortably from a sophisticated graphical user interface. The NI-SPEKTRAL DELAY runs either stand-alone or as a plug-in. It offers professional sound quality and can be fully controlled by MIDI.

Edit Graphs which are intuitive to use and packed with comfortable edit functions are used to set up the delay times and feedback levels for the bands: each of the up to 160 bands per side can be delayed separately and fed back to the delay input with an individual amount. The delay times can be set freely or according to the rhythm via a selectable note grid. The maximum delay time is 12 seconds. The effects achievable with this band delay include rather subtle colorings as well as rhythmic courses of the partial tones and dense, atmospheric sound textures.

The modulation effects of the NI-SPEKTRAL DELAY, which are expandable by plug-ins, are applied in the frequency domain of the audio signal and offer many unusual processing options - such as rotation of the frequency bands or reverb simulation by smearing the amplitude courses of the bands. The modulation effects make a big contribution to the unique sound possibilities of the NI-SPEKTRAL DELAY.

The amplitudes of the bands are also controlled intuitively by drawing in an Edith Graph with the mouse. In contrast to those of conventional filters, the filter curves resulting from this can have any shape and therefore make possible even very extreme filter settings and sweeps. For example, it is possible to completely filter all frequencies while some very narrow frequency bands are still audible. The filter curves can be drawn together or separately for the two channels of a stereo signal.

Separate feedback delays for up to 160 bands per stereo side, unique modulation effects and freely drawable filter curves make the NI-SPEKTRAL DELAY an exceptional flexible, powerful and creative effects tool. All parameters such as filter, delay and feedback settings can be modulated with an integrated LFO or via MIDI. This makes it possible to create very organic and lively effects which can easily be played live.
