The filter state object whose coefficients you wish to update.
An input array of single-precision coefficients.
First section to update in each channel.
First channel to update.
Number of sections to update in each channel.
Number of channels to update.
The existing setup is modified by applying the values in
coeffs to the specified ranges of channels and sections.
This function does not allocate any additional memory.
coeffs array contains only the new coefficients, laid out in the same way as the original array of coefficients – as if laying out original coefficients for
nsec sections in
nchn channels. See discussion for
