void AXSetMultiVoiceBiquad(AXMVPB *mv, const AXPBBIQUAD *biquad);
||Pointer to the multi-voice.
||Pointer to the application-initialized
Applies the biquad filter parameters to all voices in the specified multi-voice. To update the coefficients
after the biquad filter has been enabled, use

Due to the difference in PPC and DSP architectures, PPC being a floating-point processor and DSP a fixed
point processor, the output of a voice processed on PPC might sound different than the same voice processed
on DSP. This is especially true when using biquad and LPF filters. DSP has a 16-bit width to represent
coefficients. This limitation imposes restrictions on the realization of stable filters for extreme cut-off
filters. For example, realizing a low pass filter using biquad less than 160Hz, might be difficult for
all inputs. It is up to the developers to make sure that the filters they submit to the DSP are stable for
all the inputs that are processed through such a filter.
