Page 4: Introduction
Introduction Re-synthesizing second and third harmonics separately Improving clarity, intelligibi- lity and depth without introducing harshness Warm and smooth sounding harmonic re-synthesis Easy and intuitive operation SPL digital audio processors are designed in cooperation with Spectral Design of Bremen, Germany, who are responsible for the DSP programming. -

the small timing glitches that would otherwise occur when switching the process in and out. Up to 99 presets can be stored and changed using a MIDI program change command. isplay: The S is equipped with two PPM-meters PECTRALIZER that feature high resolution in the important region immedia- tely before 0dB. -
Page 6: Connections, Installing Updates
Connections Before connecting the S PECTRALIZER connected units. The rear panel provides AES/EBU- and S/P-DIF-inputs and outputs. Any additional channel, status and user-bits are passed through unaltered, and the outputs can be used at the same time if required. The S operates with 24 bit word width. -

Page 9: Frequency
sets the starting frequency of the highpass filter. REQUENCY Above this frequency second and third harmonics are being generated. The highpass filter can be varied between 1 kHz and 7 kHz in steps of 500 Hz. controls the mix level between the processed and the unprocessed signal. -

3rd Harmonic Diagram 3: ARMONIC The illustration shows the FFT spectrums of the odd harmonics for a measuring signal of 3 kHz. Diagram 4: If two frequencies are fed into the Spectralizer (here 3 and 4 kHz) also the diffe- rential tone (here 7 kHz) are being produced All measurements at:... -
Page 11: Density
increases the loudness of the generated harmonics by ENSITY applying different “compression ratios”. The control offers six positions. Adjustment: If D is set to 0, the generated harmonics ENSITY have low intensity even at high values for 2 . The increase in high frequencies is mostly created by ARMONIC the highpass filtering, which applies a shelving equalizing above the adjusted F... -

In order to increase operation safety only send the necessary MIDI data to the S . Unnecessary information might PECTRALIZER lead to system failure. You can use MIDI to create a MIDI fade out, if you are working with a digital console that does not provide master inserts. -
