 Premiere Ensembles Nietszche Delay
Spektral DelayNovember 19, 2008 This unusual audio effect splits incoming audio into any number of frequency bands, then applies a modulating filter delay to each band! Nietszche (Click image for bigger view)  For this spectral delay, multiple Low Frequency Oscillators (LFOs) can modulate the delay, overdrive, feedback, and pan across the spectrum by diffrerent amounts for each band. The Frequency, symmetry, and phase of the LFOs can also be set to different amounts for each band. The number of bands and the band separation is selectable. There are multiple versions of the effect to provide low CPU utilization or more control. There are also mono and stereo versions. Some ExamplesThis is a demonstration of modulation parameters for creating mobile comb-like striations in a string sound. The instrument is Hume4, but the delay can be applied as a plugin to any effect. Nietzsche spectral delay is superb for overlaying unusual disco scratch and sound effects on rhythms, as shown in this extended example. The effect is first played dry, then various presets applied. Some DetailsThere are various clever ways to modulate the signal and delays and other characteristics separately for each band. The singly poly-display unit changes view to show different parameters changing across all the bands, depending which you wish to tweak. All the knobs labeled Spectral adjust the parameter across the filter delay bank--you can adjust +/- values to linearly scale the parameter up or down the bank of filter delays just by moving one knob. This creates unique raking and warbling effects. Try the spectral delay knob first, it should be obvious after that. All the Grouping knobs quantize the fixed spectral delay values into sets. You can then move the sets up and up and down the filter delay bank with the "rotate" knob. This is an excellent effect for live performance. The Spectral LFO can also provide varying amplitude up and down the spectral bands. If you adjust its parameters and you will see many types of modulation possibilities. Additionally there is Q modulation for the filters; and on the output, a 4-band Equalizer and 4-band Limiter with individual limiting on each band. Because spectral delays isolate and enhance individual bands, the harmonic spread can become centered in a particular region. The output section allows balancing across the spectra, or enhancing of a particular spectral zone, and also of course, saving of the EQ curve with the snapshot. You can change the number of frequency taps by changing the instrument's number of voices. By default it's set to 32 voices. I'd be grateful for feedback on how well it runs on your machines with 100 voices. I have been able to use the effect on a 1.6GHz Pentium with 100 voices. The ensemble arrives hooked up to a drum sequencer for demo. (Turn on the Reaktor clock after opening the ensemble for instant gratification.) After the snaps, the easiest way to make sense of it is to turn the LFO amplitude to 0 and twiddle the DELAY knobs. (The GROUP and ROTATE only have effect if Spectral value is not zero). It sounds great with Carbon. Carbon2's default patches play with >100 voices on a 2.66ghz P4 and Windows XP. Obtaining Nietszche Spectral DelayHope you have fun with it! I am only asking $30 for this design, and customers are entitled to feature requests and free upgrades. At each upgrade, the cost may also rise, so purchasing this ensemble now could save you at least twice as much in the long term! |
