what’s new! /omnia /
… not in the number of bands. Anyone who thinks adding more bands of clipping and filtering to the system is wasting DSP cycles, or
computer MIPS, along with wasting your time with a lot of marketing rhetoric. The answer lies in understanding the range of frequen-
cies that generate both harmonic and intermodulation distortion, then applying various masking means to suppress both simultane-
ously as they are generated. Much easier said than done! It’s a combination of breaking down the audio spectrum by octaves and
interaction with the Gibbs Phenomenon. Almost explained too much already. Suffice it to say, the prior statement - along with
technology - enables a clipping system that suppresses BOTH harmonic and IMD distortion components when aggressive processing
levels are required. Additionally, and more importantly, this new clipping method does not employ the use of dynamic compressors or
limiters to control depth of clipping in order to minimize clipping induced IMD. There have been, and remain, a few proponents who
utilize this method to reduce generated IMD, but it is at the expense of added dynamic intermod which manifests itself as audio
pumping and hole punching.
It is easy to see. For the exact same amount of clipping employed, midrange, presence, and treble IMD is gone! With the new method,
Kelly Clarkson’s test segment does not possess any of the bacon frying sizzle annoyance as heard prior with all other clipping systems. As
a matter of subjective observance, all audio auditioned through this new method sounds cleaner for the same given level of loudness. It
does not matter if the content source contains deep-rich bass or not: the audio signal is subjectively cleaner for the same level of loudness.
THE ANSWER IS...
PROOF
Figure-9, Clipper Induced IMD: 100 Hz & 5 kHz Figure-10, Clipper Induced IMD: 100 Hz & 7.5 kHz
Figure-11, Clipper Induced IMD: 100 Hz & 10 kHz
Figure-12, Clipper Induced IMD: 100 Hz & 12.5 kHz
Figure-13, Clipper Induced IMD: 100 Hz & 15 kHz
Running the same IMD tests, as mentioned earlier, now offer the following results. Compare figures 9 - 13 to those of figures 4 - 8 of both
the old and new methods.
