The NI-SPEKTRAL DELAY differs from the many other audio effects in that it uses real-time FFT (Fast Fourier Transformation) to split up each channel of a stereo signal in up to 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 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 int
