audioiirfilter implements a generic audio IIR filter. Before usage the "a" and "b" properties have to be set to the filter coefficients that should be used.
The filter coefficients describe the numerator and denominator of the transfer function.
To change the filter coefficients whenever the sampling rate changes the "rate-changed" signal can be used. This should be done for most IIR filters as they're depending on the sampling rate.
