Native Instruments has just unveiled Spektral Delay ($199), the first in a series of Fast Fourier Transform (FFT)-based processors. Spektral Delay uses FFTs to divide a waveform into 1,024 frequency bands. Each of these frequencies can then be processed individually. Each channel also can be processed separately.
Once the audio is separated into frequency bands, you can perform several types of processing simultaneously on each band. The Input-Amplitude-Matrix lets you attenuate each band by up to 50 dB. The Delay Matrix gives you a maximum of 12 seconds of delay for each band, while the Feedback Matrix lets you control the amount of signal fed back into the delay. An LFO, with a choice of six waveforms, allows you to modulate each band.
All parameters can be controlled via MIDI, and Spektral Delay works either as a VST 2.0 plug-in or as a stand-alone processor.
Spektral Delay is compatible with both Macintosh and Windows, and works with ASIO, Sound Manager, Direct Sound, and MME drivers. RTAS and MAS versions of the plug-in are in development.
