Roger Nichols Digital Releases SPL-izer

Roger Nichols Digital has released SPL-izer, a multiband signal processor for Mac and Windows. SPL-izer divides an incoming signal into different frequency bands and applies processing to each band individually.

The SPL-IZER is an adjustable 3 band 24db per octave FIR (Finite Impulse Response) frequency splitter that allows the three bands to be isolated and routed to aux or instrument tracks for separate processing. The use of FIR filters ensures that no phase shifting occurs at the frequency split points. With this tool, one can use for example ones favorite single band compressor and make it 3 band.

There is of course a myriad of potential uses. One use we found was to use the Spl-izer in front of the reverb auxes. No reverb on the low end, the original reverb on the mid section and the same reverb but with reduced decay on the high end. Acoustic rhythm guitar track run through the Spl-izer: low end muted, mid section straight through and a short echo/ chorus only on the high end.

Because a keyboard covers such a wide frequency range, you might want to process one frequency range differently. For example, suppose you’ve loaded a cool imitation-Rhodes preset, and you want the lower notes to “bark” more than the upper notes. Apply multiband distortion, and apply subtle amounts of distortion only to the lower frequencies – say, below 200Hz. Now those lower keys will have a gritty character, while the others sound normal.

• Spl-izer features user adjustable frequency split point and audio levels.
• The low to mid split point can be set from 80Hz to 1475 Hz.
• The mid to high split point from 80Hz to 16kHz.
• The user can choose between using Hanning or Blackman windows.
• The various level meters feature RNDigital’s proprietary +8db input meter with peak and RMS level indicators.
• The direct output of the plug-in can be switched between Mute, Sum, Low Band, Mid Band and High Band for instant monitoring.
• The three bands created by the the splitter each have their own level meter and adjustable gain. The plug-in makes these signals available to your DAW as individual busses.

The Spl-izer created buss signals ( SPL-IZER LOW, SPL-IZER MID and SPL-IZER HI) can then be insterted as input on any other track for further processing. A large Band level meter indicates both the crossover points and the audio level of each band.

Roger Nichols Digital’s SPL-izer is available now for $129.00. More information on Roger Nichols Digital SPL-izer.
