A network configuration file is generated at a host computer and downloaded to a digital camera. A spectrally smooth canceler equalization is used, reducing artifacts for listeners away from the sweet spot and further enlarging the sweet spot. Bypassing a communication bus to a processor, the direct transfer allows for a faster transfer to the volatile memory. The structure of the polyalkylated arylalkyl sulfonic acids produced using the process described in the present invention is shown below:WhereR1, R2 and R3 are each separately and independently H, alkyl, a, CH2O)b, or cCH2O)d,m+n=8 to 28R4=CH2CH3, CH2CH3Y or YpCHqYp+q=0 to 27a=1 to 30b=1 to 30c+d=2 to 30Y=CH3, COOH, CH2OH, CH2a, CH2CH2O)b, CH2cCH2O)d, aromatic, or substituted aromatic.
