The 'edge' for this saw variant (1/F amplitude spectrum) is made by integrating the anti-aliased pulse. + +Aliases should be below -80dB for fundamental frequencies below the sample rate / 6 (i.e. up to 8 kHz at Fsamp = 48 kHz). This frequency range includes the fundamental frequencies of all known musical instruments. + +Tests by Matthias Nagorni revealed the output sounded quite 'harsh' when compared to his analogue instruments. Comparing the spectra, it became clear that a mathematically 'exact' spectrum was not desirable from a musical point of view. For this reason, a built-in lowpass filter was added. The default setting (0.5) will yield output identical to that of the Moog Voyager.""" . |
